Input: What is (are) Causes of Diabetes ?

Output:
Diabetes is a complex group of diseases with a variety of causes. People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.

Diabetes is a disorder of metabolismthe way the body uses digested food for energy. The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose, a form of sugar that enters the bloodstream. With the help of the hormone insulin, cells throughout the body absorb glucose and use it for energy. Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both.

Insulin is made in the pancreas, an organ located behind the stomach. The pancreas contains clusters of cells called islets. Beta cells within the islets make insulin and release it into the blood.

If beta cells dont produce enough insulin, or the body doesnt respond to the insulin that is present, glucose builds up in the blood instead of being absorbed by cells in the body, leading to prediabetes or diabetes. Prediabetes is a condition in which blood glucose levels or A1C levelswhich reflect average blood glucose levelsare higher than normal but not high enough to be diagnosed as diabetes. In diabetes, the bodys cells are starved of energy despite high blood glucose levels.

Over time, high blood glucose damages nerves and blood vessels, leading to complications such as heart disease, stroke, kidney disease, blindness, dental disease, and amputations. Other complications of diabetes may include increased susceptibility to other diseases, loss of mobility with aging, depression, and pregnancy problems. No one is certain what starts the processes that cause diabetes, but scientists believe genes and environmental factors interact to cause diabetes in most cases.

The two main types of diabetes are type 1 diabetes and type 2 diabetes. A third type, gestational diabetes, develops only during pregnancy. Other types of diabetes are caused by defects in specific genes, diseases of the pancreas, certain drugs or chemicals, infections, and other conditions. Some people show signs of both type 1 and type 2 diabetes. </s>


Input: What causes Causes of Diabetes ?

Output:
Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells in the pancreas. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells. In type 1 diabetes, beta cell destruction may take place over several years, but symptoms of the disease usually develop over a short period of time.

Type 1 diabetes typically occurs in children and young adults, though it can appear at any age. In the past, type 1 diabetes was called juvenile diabetes or insulin-dependent diabetes mellitus.

Latent autoimmune diabetes in adults (LADA) may be a slowly developing kind of type 1 diabetes. Diagnosis usually occurs after age 30. In LADA, as in type 1 diabetes, the bodys immune system destroys the beta cells. At the time of diagnosis, people with LADA may still produce their own insulin, but eventually most will need insulin shots or an insulin pump to control blood glucose levels.

Genetic Susceptibility

Heredity plays an important part in determining who is likely to develop type 1 diabetes. Genes are passed down from biological parent to child. Genes carry instructions for making proteins that are needed for the bodys cells to function. Many genes, as well as interactions among genes, are thought to influence susceptibility to and protection from type 1 diabetes. The key genes may vary in different population groups. Variations in genes that affect more than 1 percent of a population group are called gene variants.

Certain gene variants that carry instructions for making proteins called human leukocyte antigens (HLAs) on white blood cells are linked to the risk of developing type 1 diabetes. The proteins produced by HLA genes help determine whether the immune system recognizes a cell as part of the body or as foreign material. Some combinations of HLA gene variants predict that a person will be at higher risk for type 1 diabetes, while other combinations are protective or have no effect on risk.

While HLA genes are the major risk genes for type 1 diabetes, many additional risk genes or gene regions have been found. Not only can these genes help identify people at risk for type 1 diabetes, but they also provide important clues to help scientists better understand how the disease develops and identify potential targets for therapy and prevention.

Genetic testing can show what types of HLA genes a person carries and can reveal other genes linked to diabetes. However, most genetic testing is done in a research setting and is not yet available to individuals. Scientists are studying how the results of genetic testing can be used to improve type 1 diabetes prevention or treatment.

Autoimmune Destruction of Beta Cells

In type 1 diabetes, white blood cells called T cells attack and destroy beta cells. The process begins well before diabetes symptoms appear and continues after diagnosis. Often, type 1 diabetes is not diagnosed until most beta cells have already been destroyed. At this point, a person needs daily insulin treatment to survive. Finding ways to modify or stop this autoimmune process and preserve beta cell function is a major focus of current scientific research.

Recent research suggests insulin itself may be a key trigger of the immune attack on beta cells. The immune systems of people who are susceptible to developing type 1 diabetes respond to insulin as if it were a foreign substance, or antigen. To combat antigens, the body makes proteins called antibodies. Antibodies to insulin and other proteins produced by beta cells are found in people with type 1 diabetes. Researchers test for these antibodies to help identify people at increased risk of developing the disease. Testing the types and levels of antibodies in the blood can help determine whether a person has type 1 diabetes, LADA, or another type of diabetes.

Environmental Factors

Environmental factors, such as foods, viruses, and toxins, may play a role in the development of type 1 diabetes, but the exact nature of their role has not been determined. Some theories suggest that environmental factors trigger the autoimmune destruction of beta cells in people with a genetic susceptibility to diabetes. Other theories suggest that environmental factors play an ongoing role in diabetes, even after diagnosis.

Viruses and infections. A virus cannot cause diabetes on its own, but people are sometimes diagnosed with type 1 diabetes during or after a viral infection, suggesting a link between the two. Also, the onset of type 1 diabetes occurs more frequently during the winter when viral infections are more common. Viruses possibly associated with type 1 diabetes include coxsackievirus B, cytomegalovirus, adenovirus, rubella, and mumps. Scientists have described several ways these viruses may damage or destroy beta cells or possibly trigger an autoimmune response in susceptible people. For example, anti-islet antibodies have been found in patients with congenital rubella syndrome, and cytomegalovirus has been associated with significant beta cell damage and acute pancreatitisinflammation of the pancreas. Scientists are trying to identify a virus that can cause type 1 diabetes so that a vaccine might be developed to prevent the disease.

Infant feeding practices. Some studies have suggested that dietary factors may raise or lower the risk of developing type 1 diabetes. For example, breastfed infants and infants receiving vitamin D supplements may have a reduced risk of developing type 1 diabetes, while early exposure to cows milk and cereal proteins may increase risk. More research is needed to clarify how infant nutrition affects the risk for type 1 diabetes.

Input: What causes Causes of Diabetes ?

Output:
Type 2 diabetesthe most common form of diabetesis caused by a combination of factors, including insulin resistance, a condition in which the bodys muscle, fat, and liver cells do not use insulin effectively. Type 2 diabetes develops when the body can no longer produce enough insulin to compensate for the impaired ability to use insulin. Symptoms of type 2 diabetes may develop gradually and can be subtle; some people with type 2 diabetes remain undiagnosed for years.

Type 2 diabetes develops most often in middle-aged and older people who are also overweight or obese. The disease, once rare in youth, is becoming more common in overweight and obese children and adolescents. Scientists think genetic susceptibility and environmental factors are the most likely triggers of type 2 diabetes.

Genetic Susceptibility

Genes play a significant part in susceptibility to type 2 diabetes. Having certain genes or combinations of genes may increase or decrease a persons risk for developing the disease. The role of genes is suggested by the high rate of type 2 diabetes in families and identical twins and wide variations in diabetes prevalence by ethnicity. Type 2 diabetes occurs more frequently in African Americans, Alaska Natives, American Indians, Hispanics/Latinos, and some Asian Americans, Native Hawaiians, and Pacific Islander Americans than it does in non-Hispanic whites.

Recent studies have combined genetic data from large numbers of people, accelerating the pace of gene discovery. Though scientists have now identified many gene variants that increase susceptibility to type 2 diabetes, the majority have yet to be discovered. The known genes appear to affect insulin production rather than insulin resistance. Researchers are working to identify additional gene variants and to learn how they interact with one another and with environmental factors to cause diabetes.

Studies have shown that variants of the TCF7L2 gene increase susceptibility to type 2 diabetes. For people who inherit two copies of the variants, the risk of developing type 2 diabetes is about 80 percent higher than for those who do not carry the gene variant.1 However, even in those with the variant, diet and physical activity leading to weight loss help delay diabetes, according to the Diabetes Prevention Program (DPP), a major clinical trial involving people at high risk.

Genes can also increase the risk of diabetes by increasing a persons tendency to become overweight or obese. One theory, known as the thrifty gene hypothesis, suggests certain genes increase the efficiency of metabolism to extract energy from food and store the energy for later use. This survival trait was advantageous for populations whose food supplies were scarce or unpredictable and could help keep people alive during famine. In modern times, however, when high-calorie foods are plentiful, such a trait can promote obesity and type 2 diabetes.

Obesity and Physical Inactivity

Physical inactivity and obesity are strongly associated with the development of type 2 diabetes. People who are genetically susceptible to type 2 diabetes are more vulnerable when these risk factors are present.

An imbalance between caloric intake and physical activity can lead to obesity, which causes insulin resistance and is common in people with type 2 diabetes. Central obesity, in which a person has excess abdominal fat, is a major risk factor not only for insulin resistance and type 2 diabetes but also for heart and blood vessel disease, also called cardiovascular disease (CVD). This excess belly fat produces hormones and other substances that can cause harmful, chronic effects in the body such as damage to blood vessels.

The DPP and other studies show that millions of people can lower their risk for type 2 diabetes by making lifestyle changes and losing weight. The DPP proved that people with prediabetesat high risk of developing type 2 diabetescould sharply lower their risk by losing weight through regular physical activity and a diet low in fat and calories. In 2009, a follow-up study of DPP participantsthe Diabetes Prevention Program Outcomes Study (DPPOS)showed that the benefits of weight loss lasted for at least 10 years after the original study began.2

Insulin Resistance

Insulin resistance is a common condition in people who are overweight or obese, have excess abdominal fat, and are not physically active. Muscle, fat, and liver cells stop responding properly to insulin, forcing the pancreas to compensate by producing extra insulin. As long as beta cells are able to produce enough insulin, blood glucose levels stay in the normal range. But when insulin production falters because of beta cell dysfunction, glucose levels rise, leading to prediabetes or diabetes.

Abnormal Glucose Production by the Liver

In some people with diabetes, an abnormal increase in glucose production by the liver also contributes to high blood glucose levels. Normally, the pancreas releases the hormone glucagon when blood glucose and insulin levels are low. Glucagon stimulates the liver to produce glucose and release it into the bloodstream. But when blood glucose and insulin levels are high after a meal, glucagon levels drop, and the liver stores excess glucose for later, when it is needed. For reasons not completely understood, in many people with diabetes, glucagon levels stay higher than needed. High glucagon levels cause the liver to produce unneeded glucose, which contributes to high blood glucose levels. Metformin, the most commonly used drug to treat type 2 diabetes, reduces glucose production by the liver.

The Roles of Insulin and Glucagon in Normal Blood Glucose Regulation

A healthy persons body keeps blood glucose levels in a normal range through several complex mechanisms. Insulin and glucagon, two hormones made in the pancreas, help regulate blood glucose levels:

- Insulin, made by beta cells, lowers elevated blood glucose levels.  - Glucagon, made by alpha cells, raises low blood glucose levels.

- Insulin helps muscle, fat, and liver cells absorb glucose from the bloodstream, lowering blood glucose levels.  - Insulin stimulates the liver and muscle tissue to store excess glucose. The stored form of glucose is called glycogen.  - Insulin also lowers blood glucose levels by reducing glucose production in the liver.

- Glucagon signals the liver and muscle tissue to break down glycogen into glucose, which enters the bloodstream and raises blood glucose levels.  - If the body needs more glucose, glucagon stimulates the liver to make glucose from amino acids.

Metabolic Syndrome

Metabolic syndrome, also called insulin resistance syndrome, refers to a group of conditions common in people with insulin resistance, including

- higher than normal blood glucose levels  - increased waist size due to excess abdominal fat  - high blood pressure  - abnormal levels of cholesterol and triglycerides in the blood

Cell Signaling and Regulation

Cells communicate through a complex network of molecular signaling pathways. For example, on cell surfaces, insulin receptor molecules capture, or bind, insulin molecules circulating in the bloodstream. This interaction between insulin and its receptor prompts the biochemical signals that enable the cells to absorb glucose from the blood and use it for energy.

Problems in cell signaling systems can set off a chain reaction that leads to diabetes or other diseases. Many studies have focused on how insulin signals cells to communicate and regulate action. Researchers have identified proteins and pathways that transmit the insulin signal and have mapped interactions between insulin and body tissues, including the way insulin helps the liver control blood glucose levels. Researchers have also found that key signals also come from fat cells, which produce substances that cause inflammation and insulin resistance.

This work holds the key to combating insulin resistance and diabetes. As scientists learn more about cell signaling systems involved in glucose regulation, they will have more opportunities to develop effective treatments.

Beta Cell Dysfunction

Scientists think beta cell dysfunction is a key contributor to type 2 diabetes. Beta cell impairment can cause inadequate or abnormal patterns of insulin release. Also, beta cells may be damaged by high blood glucose itself, a condition called glucose toxicity.

Scientists have not determined the causes of beta cell dysfunction in most cases. Single gene defects lead to specific forms of diabetes called maturity-onset diabetes of the young (MODY). The genes involved regulate insulin production in the beta cells. Although these forms of diabetes are rare, they provide clues as to how beta cell function may be affected by key regulatory factors. Other gene variants are involved in determining the number and function of beta cells. But these variants account for only a small percentage of type 2 diabetes cases. Malnutrition early in life is also being investigated as a cause of beta cell dysfunction. The metabolic environment of the developing fetus may also create a predisposition for diabetes later in life.

Risk Factors for Type 2 Diabetes

People who develop type 2 diabetes are more likely to have the following characteristics:

- age 45 or older  - overweight or obese  - physically inactive  - parent or sibling with diabetes  - family background that is African American, Alaska Native, American Indian, Asian American, Hispanic/Latino, or Pacific Islander American  - history of giving birth to a baby weighing more than 9 pounds  - history of gestational diabetes  - high blood pressure140/90 or aboveor being treated for high blood pressure  - high-density lipoprotein (HDL), or good, cholesterol below 35 milligrams per deciliter (mg/dL), or a triglyceride level above 250 mg/dL  - polycystic ovary syndrome, also called PCOS  - prediabetesan A1C level of 5.7 to 6.4 percent; a fasting plasma glucose test result of 100125 mg/dL, called impaired fasting glucose; or a 2-hour oral glucose tolerance test result of 140199, called impaired glucose tolerance  - acanthosis nigricans, a condition associated with insulin resistance, characterized by a dark, velvety rash around the neck or armpits  - history of CVD

The American Diabetes Association (ADA) recommends that testing to detect prediabetes and type 2 diabetes be considered in adults who are overweight or obese and have one or more additional risk factors for diabetes. In adults without these risk factors, testing should begin at age 45. </s>

Output:
Insulin Resistance and Beta Cell Dysfunction

Hormones produced by the placenta and other pregnancy-related factors contribute to insulin resistance, which occurs in all women during late pregnancy. Insulin resistance increases the amount of insulin needed to control blood glucose levels. If the pancreas cant produce enough insulin due to beta cell dysfunction, gestational diabetes occurs.

As with type 2 diabetes, excess weight is linked to gestational diabetes. Overweight or obese women are at particularly high risk for gestational diabetes because they start pregnancy with a higher need for insulin due to insulin resistance. Excessive weight gain during pregnancy may also increase risk.

Family History

Having a family history of diabetes is also a risk factor for gestational diabetes, suggesting that genes play a role in its development. Genetics may also explain why the disorder occurs more frequently in African Americans, American Indians, and Hispanics/Latinos. Many gene variants or combinations of variants may increase a womans risk for developing gestational diabetes. Studies have found several gene variants associated with gestational diabetes, but these variants account for only a small fraction of women with gestational diabetes.

Future Risk of Type 2 Diabetes

Because a womans hormones usually return to normal levels soon after giving birth, gestational diabetes disappears in most women after delivery. However, women who have gestational diabetes are more likely to develop gestational diabetes with future pregnancies and develop type 2 diabetes.3 Women with gestational diabetes should be tested for persistent diabetes 6 to 12 weeks after delivery and at least every 3 years thereafter.

Also, exposure to high glucose levels during gestation increases a childs risk for becoming overweight or obese and for developing type 2 diabetes later on. The result may be a cycle of diabetes affecting multiple generations in a family. For both mother and child, maintaining a healthy body weight and being physically active may help prevent type 2 diabetes. </s>

Other types of diabetes have a variety of possible causes.

Genetic Mutations Affecting Beta Cells, Insulin, and Insulin Action

Some relatively uncommon forms of diabetes known as monogenic diabetes are caused by mutations, or changes, in a single gene. These mutations are usually inherited, but sometimes the gene mutation occurs spontaneously. Most of these gene mutations cause diabetes by reducing beta cells ability to produce insulin.

The most common types of monogenic diabetes are neonatal diabetes mellitus (NDM) and MODY. NDM occurs in the first 6 months of life. MODY is usually found during adolescence or early adulthood but sometimes is not diagnosed until later in life. More information about NDM and MODY is provided in the NIDDK health topic, Monogenic Forms of Diabetes.

Other rare genetic mutations can cause diabetes by damaging the quality of insulin the body produces or by causing abnormalities in insulin receptors.

Other Genetic Diseases

Diabetes occurs in people with Down syndrome, Klinefelter syndrome, and Turner syndrome at higher rates than the general population. Scientists are investigating whether genes that may predispose people to genetic syndromes also predispose them to diabetes.

The genetic disorders cystic fibrosis and hemochromatosis are linked to diabetes. Cystic fibrosis produces abnormally thick mucus, which blocks the pancreas. The risk of diabetes increases with age in people with cystic fibrosis. Hemochromatosis causes the body to store too much iron. If the disorder is not treated, iron can build up in and damage the pancreas and other organs.

Damage to or Removal of the Pancreas

Pancreatitis, cancer, and trauma can all harm the pancreatic beta cells or impair insulin production, thus causing diabetes. If the damaged pancreas is removed, diabetes will occur due to the loss of the beta cells.

Endocrine Diseases

Endocrine diseases affect organs that produce hormones. Cushings syndrome and acromegaly are examples of hormonal disorders that can cause prediabetes and diabetes by inducing insulin resistance. Cushings syndrome is marked by excessive production of cortisolsometimes called the stress hormone. Acromegaly occurs when the body produces too much growth hormone. Glucagonoma, a rare tumor of the pancreas, can also cause diabetes. The tumor causes the body to produce too much glucagon. Hyperthyroidism, a disorder that occurs when the thyroid gland produces too much thyroid hormone, can also cause elevated blood glucose levels.

Autoimmune Disorders

Rare disorders characterized by antibodies that disrupt insulin action can lead to diabetes. This kind of diabetes is often associated with other autoimmune disorders such as lupus erythematosus. Another rare autoimmune disorder called stiff-man syndrome is associated with antibodies that attack the beta cells, similar to type 1 diabetes.

Medications and Chemical Toxins

Some medications, such as nicotinic acid and certain types of diuretics, anti-seizure drugs, psychiatric drugs, and drugs to treat human immunodeficiency virus (HIV), can impair beta cells or disrupt insulin action. Pentamidine, a drug prescribed to treat a type of pneumonia, can increase the risk of pancreatitis, beta cell damage, and diabetes. Also, glucocorticoidssteroid hormones that are chemically similar to naturally produced cortisolmay impair insulin action. Glucocorticoids are used to treat inflammatory illnesses such as rheumatoid arthritis, asthma, lupus, and ulcerative colitis.

Many chemical toxins can damage or destroy beta cells in animals, but only a few have been linked to diabetes in humans. For example, dioxina contaminant of the herbicide Agent Orange, used during the Vietnam Warmay be linked to the development of type 2 diabetes. In 2000, based on a report from the Institute of Medicine, the U.S. Department of Veterans Affairs (VA) added diabetes to the list of conditions for which Vietnam veterans are eligible for disability compensation. Also, a chemical in a rat poison no longer in use has been shown to cause diabetes if ingested. Some studies suggest a high intake of nitrogen-containing chemicals such as nitrates and nitrites might increase the risk of diabetes. Arsenic has also been studied for possible links to diabetes.

Lipodystrophy

Lipodystrophy is a condition in which fat tissue is lost or redistributed in the body. The condition is associated with insulin resistance and type 2 diabetes. </s>

Input: What is (are) Diabetes, Heart Disease, and Stroke ?

Output:
Diabetes is a disorder of metabolismthe way our bodies use digested food for energy. Most of the food we eat is broken down into glucose, the form of sugar in the blood. Glucose is the body's main source of fuel.

After digestion, glucose enters the bloodstream. Then glucose goes to cells throughout the body where it is used for energy. However, a hormone called insulin must be present to allow glucose to enter the cells. Insulin is a hormone produced by the pancreas, a large gland behind the stomach.

In people who do not have diabetes, the pancreas automatically produces the right amount of insulin to move glucose from blood into the cells. However, diabetes develops when the pancreas does not make enough insulin, or the cells in the muscles, liver, and fat do not use insulin properly, or both. As a result, the amount of glucose in the blood increases while the cells are starved of energy.

Over time, high blood glucose levels damage nerves and blood vessels, leading to complications such as heart disease and stroke, the leading causes of death among people with diabetes. Uncontrolled diabetes can eventually lead to other health problems as well, such as vision loss, kidney failure, and amputations. </s>

If you have diabetes, you are at least twice as likely as someone who does not have diabetes to have heart disease or a stroke.

Women who have not gone through menopause usually have less risk of heart disease than men of the same age. But women of all ages with diabetes have an increased risk of heart disease because diabetes cancels out the protective effects of being a woman in her child-bearing years.

People with diabetes who have already had one heart attack run an even greater risk of having a second one. In addition, heart attacks in people with diabetes are more serious and more likely to result in death. High blood glucose levels over time can lead to increased deposits of fatty materials on the insides of the blood vessel walls. These deposits may affect blood flow, increasing the chance of clogging and hardening of blood vessels (atherosclerosis). </s>

Input: Who is at risk for Diabetes, Heart Disease, and Stroke? ?

Output:
Diabetes itself is a risk factor for heart disease and stroke. Also, many people with diabetes have other conditions that increase their chance of developing heart disease and stroke. These conditions are called risk factors. One risk factor for heart disease and stroke is having a family history of heart disease. If one or more members of your family had a heart attack at an early age (before age 55 for men or 65 for women), you may be at increased risk.

You can't change whether heart disease runs in your family, but you can take steps to control the other risk factors for heart disease listed here:

- Having central obesity. Central obesity means carrying extra weight around the waist, as opposed to the hips. A waist measurement of more than 40 inches for men and more than 35 inches for women means you have central obesity. Your risk of heart disease is higher because abdominal fat can increase the production of LDL (bad) cholesterol, the type of blood fat that can be deposited on the inside of blood vessel walls.  - Having abnormal blood fat (cholesterol) levels.      - LDL cholesterol can build up inside your blood vessels, leading to narrowing and hardening of your arteriesthe blood vessels that carry blood from the heart to the rest of the body. Arteries can then become blocked. Therefore, high levels of LDL cholesterol raise your risk of getting heart disease.    - Triglycerides are another type of blood fat that can raise your risk of heart disease when the levels are high.    - HDL (good) cholesterol removes deposits from inside your blood vessels and takes them to the liver for removal. Low levels of HDL cholesterol increase your risk for heart disease.    - Having high blood pressure. If you have high blood pressure, also called hypertension, your heart must work harder to pump blood. High blood pressure can strain the heart, damage blood vessels, and increase your risk of heart attack, stroke, eye problems, and kidney problems.  - Smoking. Smoking doubles your risk of getting heart disease. Stopping smoking is especially important for people with diabetes because both smoking and diabetes narrow blood vessels. Smoking also increases the risk of other long-term complications, such as eye problems. In addition, smoking can damage the blood vessels in your legs and increase the risk of amputation. </s>

Input: How to prevent Diabetes, Heart Disease, and Stroke ?

Output:
Even if you are at high risk for heart disease and stroke, you can help keep your heart and blood vessels healthy. You can do so by taking the following steps:

- Make sure that your diet is "heart-healthy." Meet with a registered dietitian to plan a diet that meets these goals:      - Include at least 14 grams of fiber daily for every 1,000 calories consumed. Foods high in fiber may help lower blood cholesterol. Oat bran, oatmeal, whole-grain breads and cereals, dried beans and peas (such as kidney beans, pinto beans, and black-eyed peas), fruits, and vegetables are all good sources of fiber. Increase the amount of fiber in your diet gradually to avoid digestive problems.    - Cut down on saturated fat. It raises your blood cholesterol level. Saturated fat is found in meats, poultry skin, butter, dairy products with fat, shortening, lard, and tropical oils such as palm and coconut oil. Your dietitian can figure out how many grams of saturated fat should be your daily maximum amount.    - Keep the cholesterol in your diet to less than 300 milligrams a day. Cholesterol is found in meat, dairy products, and eggs.    - Keep the amount of trans fat in your diet to a minimum. It's a type of fat in foods that raises blood cholesterol. Limit your intake of crackers, cookies, snack foods, commercially prepared baked goods, cake mixes, microwave popcorn, fried foods, salad dressings, and other foods made with partially hydrogenated oil. In addition, some kinds of vegetable shortening and margarines have trans fat. Check for trans fat in the Nutrition Facts section on the food package.    - If you smoke, quit. Your doctor can help you find ways to quit smoking.  - Ask your doctor whether you should take aspirin. Studies have shown that taking a low dose of aspirin every day can help reduce the risk of heart disease and stroke. However, aspirin is not safe for everyone. Your doctor can tell you whether taking aspirin is right for you and exactly how much to take.  - Get prompt treatment for transient ischemic attacks (TIAs). Early treatment for TIAs, sometimes called mini-strokes, may help prevent or delay a future stroke. Signs of a TIA are sudden weakness, loss of balance, numbness, confusion, blindness in one or both eyes, double vision, difficulty speaking, or a severe headache. </s>

Output:
You can keep track of the ABCs of diabetes to make sure your treatment is working. Talk with your health care provider about the best targets for you.

A stands for A1C (a test that measures blood glucose control). Have an A1C test at least twice a year. It shows your average blood glucose level over the past 3 months. Talk with your doctor about whether you should check your blood glucose at home and how to do it.

A1C target        Below 7 percent, unless your doctor sets a different target

Blood glucose targets        Before meals    90 to 130 mg/dL        1 to 2 hours after the start of a meal    Less than 180 mg/dL

B is for blood pressure. Have it checked at every office visit.

Blood pressure target        Below 140/80 mm Hg, unless your doctor sets a different target

C is for cholesterol. Have it checked at least once a year.

Blood fat (cholesterol) targets        LDL (bad) cholesterol    Under 100 mg/dL        Triglycerides    Under 150 mg/dL        HDL (good) cholesterol For men: above 40 mg/dL For women: above 50 mg/dL

Control of the ABCs of diabetes can reduce your risk for heart disease and stroke. If your blood glucose, blood pressure, and cholesterol levels aren't on target, ask your doctor what changes in diet, activity, and medications can help you reach these goals. </s>


Input: What is (are) Diabetes, Heart Disease, and Stroke ?

Output:
Two major types of heart and blood vessel disease, also called cardiovascular disease, are common in people with diabetes: coronary artery disease (CAD) and cerebral vascular disease. People with diabetes are also at risk for heart failure. Narrowing or blockage of the blood vessels in the legs, a condition called peripheral arterial disease, can also occur in people with diabetes.

Coronary Artery Disease

Coronary artery disease, also called ischemic heart disease, is caused by a hardening or thickening of the walls of the blood vessels that go to your heart. Your blood supplies oxygen and other materials your heart needs for normal functioning. If the blood vessels to your heart become narrowed or blocked by fatty deposits, the blood supply is reduced or cut off, resulting in a heart attack.

Cerebral Vascular Disease

Cerebral vascular disease affects blood flow to the brain, leading to strokes and TIAs. It is caused by narrowing, blocking, or hardening of the blood vessels that go to the brain or by high blood pressure.

Stroke

A stroke results when the blood supply to the brain is suddenly cut off, which can occur when a blood vessel in the brain or neck is blocked or bursts. Brain cells are then deprived of oxygen and die. A stroke can result in problems with speech or vision or can cause weakness or paralysis. Most strokes are caused by fatty deposits or blood clotsjelly-like clumps of blood cellsthat narrow or block one of the blood vessels in the brain or neck. A blood clot may stay where it formed or can travel within the body. People with diabetes are at increased risk for strokes caused by blood clots.

A stroke may also be caused by a bleeding blood vessel in the brain. Called an aneurysm, a break in a blood vessel can occur as a result of high blood pressure or a weak spot in a blood vessel wall.

TIAs

TIAs are caused by a temporary blockage of a blood vessel to the brain. This blockage leads to a brief, sudden change in brain function, such as temporary numbness or weakness on one side of the body. Sudden changes in brain function also can lead to loss of balance, confusion, blindness in one or both eyes, double vision, difficulty speaking, or a severe headache. However, most symptoms disappear quickly and permanent damage is unlikely. If symptoms do not resolve in a few minutes, rather than a TIA, the event could be a stroke. The occurrence of a TIA means that a person is at risk for a stroke sometime in the future. See page 3 for more information on risk factors for stroke.

Heart Failure

Heart failure is a chronic condition in which the heart cannot pump blood properlyit does not mean that the heart suddenly stops working. Heart failure develops over a period of years, and symptoms can get worse over time. People with diabetes have at least twice the risk of heart failure as other people. One type of heart failure is congestive heart failure, in which fluid builds up inside body tissues. If the buildup is in the lungs, breathing becomes difficult.

Blockage of the blood vessels and high blood glucose levels also can damage heart muscle and cause irregular heart beats. People with damage to heart muscle, a condition called cardiomyopathy, may have no symptoms in the early stages, but later they may experience weakness, shortness of breath, a severe cough, fatigue, and swelling of the legs and feet. Diabetes can also interfere with pain signals normally carried by the nerves, explaining why a person with diabetes may not experience the typical warning signs of a heart attack.

Peripheral Arterial Disease

Another condition related to heart disease and common in people with diabetes is peripheral arterial disease (PAD). With this condition, the blood vessels in the legs are narrowed or blocked by fatty deposits, decreasing blood flow to the legs and feet. PAD increases the chances of a heart attack or stroke occurring. Poor circulation in the legs and feet also raises the risk of amputation. Sometimes people with PAD develop pain in the calf or other parts of the leg when walking, which is relieved by resting for a few minutes. </s>

Output:
At the first sign of a stroke, you should get medical care right away. If blood vessels to your brain are blocked by blood clots, the doctor can give you a "clot-busting" drug. The drug must be given soon after a stroke to be effective. Subsequent treatment for stroke includes medications and physical therapy, as well as surgery to repair the damage. Meal planning and physical activity may be part of your ongoing care. In addition, you may need medications to lower your blood glucose, blood pressure, and cholesterol and to prevent blood clots.

Input: What is (are) Diarrhea ?

Output:
Diarrhea is loose, watery stools. Having diarrhea means passing loose stools three or more times a day. Acute diarrhea is a common problem that usually lasts 1 or 2 days and goes away on its own.

Diarrhea lasting more than 2 days may be a sign of a more serious problem. Chronic diarrheadiarrhea that lasts at least 4 weeksmay be a symptom of a chronic disease. Chronic diarrhea symptoms may be continual or they may come and go.

Diarrhea of any duration may cause dehydration, which means the body lacks enough fluid and electrolyteschemicals in salts, including sodium, potassium, and chlorideto function properly. Loose stools contain more fluid and electrolytes and weigh more than solid stools.

People of all ages can get diarrhea. In the United States, adults average one bout of acute diarrhea each year,1 and young children have an average of two episodes of acute diarrhea each year.2 </s>


Input: What causes Diarrhea ?

Output:
Acute diarrhea is usually caused by a bacterial, viral, or parasitic infection. Chronic diarrhea is usually related to a functional disorder such as irritable bowel syndrome or an intestinal disease such as Crohns disease.

The most common causes of diarrhea include the following:

- Bacterial infections. Several types of bacteria consumed through contaminated food or water can cause diarrhea. Common culprits include Campylobacter, Salmonella, Shigella, and Escherichia coli (E. coli).  - Viral infections. Many viruses cause diarrhea, including rotavirus, norovirus, cytomegalovirus, herpes simplex virus, and viral hepatitis. Infection with the rotavirus is the most common cause of acute diarrhea in children. Rotavirus diarrhea usually resolves in 3 to 7 days but can cause problems digesting lactose for up to a month or longer.  - Parasites. Parasites can enter the body through food or water and settle in the digestive system. Parasites that cause diarrhea include Giardia lamblia, Entamoeba histolytica, and Cryptosporidium.  - Functional bowel disorders. Diarrhea can be a symptom of irritable bowel syndrome.  - Intestinal diseases. Inflammatory bowel disease, ulcerative colitis, Crohns disease, and celiac disease often lead to diarrhea.  - Food intolerances and sensitivities. Some people have difficulty digesting certain ingredients, such as lactose, the sugar found in milk and milk products. Some people may have diarrhea if they eat certain types of sugar substitutes in excessive quantities.  - Reaction to medicines. Antibiotics, cancer drugs, and antacids containing magnesium can all cause diarrhea.

Some people develop diarrhea after stomach surgery, which may cause food to move through the digestive system more quickly.

People who visit certain foreign countries are at risk for travelers diarrhea, which is caused by eating food or drinking water contaminated with bacteria, viruses, or parasites. Travelers diarrhea can be a problem for people traveling to developing countries in Africa, Asia, Latin America, and the Caribbean. Visitors to Canada, most European countries, Japan, Australia, and New Zealand do not face much risk for travelers diarrhea.

In many cases, the cause of diarrhea cannot be found. As long as diarrhea goes away on its own within 1 to 2 days, finding the cause is not usually necessary. </s>


Input: What are the symptoms of Diarrhea ?

Output:
Diarrhea may be accompanied by cramping, abdominal pain, nausea, an urgent need to use the bathroom, or loss of bowel control. Some infections that cause diarrhea can also cause a fever and chills or bloody stools.

Dehydration

Diarrhea can cause dehydration. Loss of electrolytes through dehydration affects the amount of water in the body, muscle activity, and other important functions.

Dehydration is particularly dangerous in children, older adults, and people with weakened immune systems. Dehydration must be treated promptly to avoid serious health problems, such as organ damage, shock, or comaa sleeplike state in which a person is not conscious.

Signs of dehydration in adults include

- thirst  - less frequent urination than usual  - dark-colored urine  - dry skin  - fatigue  - dizziness  - light-headedness

Signs of dehydration in infants and young children include

- dry mouth and tongue  - no tears when crying  - no wet diapers for 3 hours or more  - sunken eyes, cheeks, or soft spot in the skull  - high fever  - listlessness or irritability

Also, when people are dehydrated, their skin does not flatten back to normal right away after being gently pinched and released.

Anyone with signs of dehydration should see a health care provider immediately. Severe dehydration may require hospitalization.

Although drinking plenty of water is important in preventing dehydration, water does not contain electrolytes. Adults can prevent dehydration by also drinking liquids that contain electrolytes, such as fruit juices, sports drinks, caffeine-free soft drinks, and broths. Children with diarrhea should be given oral rehydration solutions such as Pedialyte, Naturalyte, Infalyte, and CeraLyte to prevent dehydration. </s>


Input: How to diagnose Diarrhea ?

Output:
If acute diarrhea lasts 2 days or less, diagnostic tests are usually not necessary. If diarrhea lasts longer or is accompanied by symptoms such as fever or bloody stools, a doctor may perform tests to determine the cause.

Diagnostic tests to find the cause of diarrhea may include the following:

- Medical history and physical examination. The doctor will ask about eating habits and medication use and will perform a physical examination to look for signs of illness.  - Stool culture. A sample of stool is analyzed in a laboratory to check for bacteria, parasites, or other signs of disease and infection.  - Blood tests. Blood tests can be helpful in ruling out certain diseases.  - Fasting tests. To find out if a food intolerance or allergy is causing the diarrhea, the doctor may ask a person to avoid foods with lactose, carbohydrates, wheat, or other ingredients to see whether the diarrhea responds to a change in diet.  - Sigmoidoscopy or colonoscopy. These tests may be used to look for signs of intestinal diseases that cause chronic diarrhea. For sigmoidoscopy, the doctor uses a thin, flexible, lighted tube with a lens on the end to look at the inside of the rectum and lower part of the colon. Colonoscopy is similar to sigmoidoscopy, but it allows the doctor to view the entire colon. </s>


Input: What are the treatments for Diarrhea ?

Output:
In most cases of diarrhea, the only treatment necessary is replacing lost fluids and electrolytes to prevent dehydration.

Over-the-counter medicines such as loperamide (Imodium) and bismuth subsalicylate (Pepto-Bismol and Kaopectate) may help stop diarrhea in adults. However, people with bloody diarrheaa sign of bacterial or parasitic infectionshould not use these medicines. If diarrhea is caused by bacteria or parasites, over-the-counter medicines may prolong the problem, so doctors usually prescribe antibiotics instead.

Medications to treat diarrhea in adults can be dangerous for infants and children and should only be given with a doctors guidance. </s>


Input: What to do for Diarrhea ?

Output:
Until diarrhea subsides, avoiding caffeine and foods that are greasy, high in fiber, or sweet may lessen symptoms. These foods can aggravate diarrhea. Some people also have problems digesting lactose during or after a bout of diarrhea. Yogurt, which has less lactose than milk, is often better tolerated. Yogurt with active, live bacterial cultures may even help people recover from diarrhea more quickly.

As symptoms improve, soft, bland foods can be added to the diet, including bananas, plain rice, boiled potatoes, toast, crackers, cooked carrots, and baked chicken without the skin or fat. For children, the health care provider may also recommend a bland diet. Once the diarrhea stops, the health care provider will likely encourage children to return to a normal and healthy diet if it can be tolerated. Infants with diarrhea should be given breast milk or full-strength formula as usual, along with oral rehydration solutions. Some children recovering from viral diarrheas have problems digesting lactose for up to a month or more. </s>


Input: How to prevent Diarrhea ?

Output:
Two types of diarrhea can be preventedrotavirus diarrhea and travelers diarrhea.

Rotavirus Diarrhea

Two oral vaccines have been approved by the U.S. Food and Drug Administration to protect children from rotavirus infections: rotavirus vaccine, live, oral, pentavalent (RotaTeq); and rotavirus vaccine, live, oral (Rotarix). RotaTeq is given to infants in three doses at 2, 4, and 6 months of age. Rotarix is given in two doses. The first dose is given when infants are 6 weeks old, and the second is given at least 4 weeks later but before infants are 24 weeks old.

Parents of infants should discuss rotavirus vaccination with a health care provider. For more information, parents can visit the Centers for Disease Control and Prevention rotavirus vaccination webpage at www.cdc.gov/vaccines/vpd-vac/rotavirus.

Travelers Diarrhea

To prevent travelers diarrhea, people traveling from the United States to developing countries should avoid

- drinking tap water, using tap water to brush their teeth, or using ice made from tap water  - drinking unpasteurized milk or milk products  - eating raw fruits and vegetables, including lettuce and fruit salads, unless they peel the fruits or vegetables themselves  - eating raw or rare meat and fish  - eating meat or shellfish that is not hot when served  - eating food from street vendors

Travelers can drink bottled water, soft drinks, and hot drinks such as coffee or tea.

People concerned about travelers diarrhea should talk with a health care provider before traveling. The health care provider may recommend that travelers bring medicine with them in case they develop diarrhea during their trip. Health care providers may advise some peopleespecially people with weakened immune systemsto take antibiotics before and during a trip to help prevent travelers diarrhea. Early treatment with antibiotics can shorten a bout of travelers diarrhea. </s>

Input: What is (are) Biliary Atresia ?

Output:
Biliary atresia is a life-threatening condition in infants in which the bile ducts inside or outside the liver do not have normal openings.

Bile ducts in the liver, also called hepatic ducts, are tubes that carry bile from the liver to the gallbladder for storage and to the small intestine for use in digestion. Bile is a fluid made by the liver that serves two main functions: carrying toxins and waste products out of the body and helping the body digest fats and absorb the fat-soluble vitamins A, D, E, and K.

With biliary atresia, bile becomes trapped, builds up, and damages the liver. The damage leads to scarring, loss of liver tissue, and cirrhosis. Cirrhosis is a chronic, or long lasting, liver condition caused by scar tissue and cell damage that makes it hard for the liver to remove toxins from the blood. These toxins build up in the blood and the liver slowly deteriorates and malfunctions. Without treatment, the liver eventually fails and the infant needs a liver transplant to stay alive.

The two types of biliary atresia are fetal and perinatal. Fetal biliary atresia appears while the baby is in the womb. Perinatal biliary atresia is much more common and does not become evident until 2 to 4 weeks after birth. Some infants, particularly those with the fetal form, also have birth defects in the heart, spleen, or intestines. </s>


Input: Who is at risk for Biliary Atresia? ?

Output: Biliary atresia is rare and only affects about one out of every 18,000 infants.1 The disease is more common in females, premature babies, and children of Asian or African American heritage. </s>


Input: What are the symptoms of Biliary Atresia ?

Output:
The first symptom of biliary atresia is jaundicewhen the skin and whites of the eyes turn yellow. Jaundice occurs when the liver does not remove bilirubin, a reddish-yellow substance formed when hemoglobin breaks down. Hemoglobin is an iron-rich protein that gives blood its red color. Bilirubin is absorbed by the liver, processed, and released into bile. Blockage of the bile ducts forces bilirubin to build up in the blood.

Other common symptoms of biliary atresia include

- dark urine, from the high levels of bilirubin in the blood spilling over into the urine  - gray or white stools, from a lack of bilirubin reaching the intestines  - slow weight gain and growth </s>


Input: What causes Biliary Atresia ?

Output:
Biliary atresia likely has multiple causes, though none are yet proven. Biliary atresia is not an inherited disease, meaning it does not pass from parent to child. Therefore, survivors of biliary atresia are not at risk for passing the disorder to their children.

Biliary atresia is most likely caused by an event in the womb or around the time of birth. Possible triggers of the event may include one or more of the following:

- a viral or bacterial infection after birth, such as cytomegalovirus, reovirus, or rotavirus  - an immune system problem, such as when the immune system attacks the liver or bile ducts for unknown reasons  - a genetic mutation, which is a permanent change in a genes structure  - a problem during liver and bile duct development in the womb  - exposure to toxic substances </s>


Input: How to diagnose Biliary Atresia ?

Output:
No single test can definitively diagnose biliary atresia, so a series of tests is needed. All infants who still have jaundice 2 to 3 weeks after birth, or who have gray or white stools after 2 weeks of birth, should be checked for liver damage.2

Infants with suspected liver damage are usually referred to a

- pediatric gastroenterologist, a doctor who specializes in childrens digestive diseases  - pediatric hepatologist, a doctor who specializes in childrens liver diseases  - pediatric surgeon, a doctor who specializes in operating on childrens livers and bile ducts

The health care provider may order some or all of the following tests to diagnose biliary atresia and rule out other causes of liver problems. If biliary atresia is still suspected after testing, the next step is diagnostic surgery for confirmation.

Blood test. A blood test involves drawing blood at a health care providers office or commercial facility and sending the sample to a lab for analysis. High levels of bilirubin in the blood can indicate blocked bile ducts.

Abdominal x rays. An x ray is a picture created by using radiation and recorded on film or on a computer. The amount of radiation used is small. An x ray is performed at a hospital or outpatient center by an x-ray technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Anesthesia is not needed, but sedation may be used to keep infants still. The infant will lie on a table during the x ray. The x-ray machine is positioned over the abdominal area. Abdominal x rays are used to check for an enlarged liver and spleen.

Ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted a radiologist. Anesthesia is not needed, but sedation may be used to keep the infant still. The images can show whether the liver or bile ducts are enlarged and whether tumors or cysts are blocking the flow of bile. An ultrasound cannot be used to diagnose biliary atresia, but it does help rule out other common causes of jaundice.

Liver scans. Liver scans are special x rays that use chemicals to create an image of the liver and bile ducts. Liver scans are performed at a hospital or outpatient facility, usually by a nuclear medicine technician. The infant will usually receive general anesthesia or be sedated before the procedure. Hepatobiliary iminodiacetic acid scanning, a type of liver scan, uses injected radioactive dye to trace the path of bile in the body. The test can show if and where bile flow is blocked. Blockage is likely to be caused by biliary atresia.

Liver biopsy. A biopsy is a procedure that involves taking a piece of liver tissue for examination with a microscope. The biopsy is performed by a health care provider in a hospital with light sedation and local anesthetic. The health care provider uses imaging techniques such as ultrasound or a computerized tomography scan to guide the biopsy needle into the liver. The liver tissue is examined in a lab by a pathologista doctor who specializes in diagnosing diseases. A liver biopsy can show whether biliary atresia is likely. A biopsy can also help rule out other liver problems, such as hepatitisan irritation of the liver that sometimes causes permanent damage.

Diagnostic surgery. During diagnostic surgery, a pediatric surgeon makes an incision, or cut, in the abdomen to directly examine the liver and bile ducts. If the surgeon confirms that biliary atresia is the problem, a Kasai procedure will usually be performed immediately. Diagnostic surgery and the Kasai procedure are performed at a hospital or outpatient facility; the infant will be under general anesthesia during surgery. </s>


Input: What are the treatments for Biliary Atresia ?

Output:
Biliary atresia is treated with surgery, called the Kasai procedure, or a liver transplant.

Kasai Procedure

The Kasai procedure, named after the surgeon who invented the operation, is usually the first treatment for biliary atresia. During a Kasai procedure, the pediatric surgeon removes the infants damaged bile ducts and brings up a loop of intestine to replace them. As a result, bile flows straight to the small intestine.

While this operation doesnt cure biliary atresia, it can restore bile flow and correct many problems caused by biliary atresia. Without surgery, infants with biliary atresia are unlikely to live past age 2. This procedure is most effective in infants younger than 3 months old, because they usually havent yet developed permanent liver damage. Some infants with biliary atresia who undergo a successful Kasai procedure regain good health and no longer have jaundice or major liver problems.

If the Kasai procedure is not successful, infants usually need a liver transplant within 1 to 2 years. Even after a successful surgery, most infants with biliary atresia slowly develop cirrhosis over the years and require a liver transplant by adulthood.

Liver Transplant

Liver transplantation is the definitive treatment for biliary atresia, and the survival rate after surgery has increased dramatically in recent years. As a result, most infants with biliary atresia now survive. Progress in transplant surgery has also increased the availability and efficient use of livers for transplantation in children, so almost all infants requiring a transplant can receive one.

In years past, the size of the transplanted liver had to match the size of the infants liver. Thus, only livers from recently deceased small children could be transplanted into infants with biliary atresia. New methods now make it possible to transplant a portion of a deceased adults liver into an infant. This type of surgery is called a reduced-size or split-liver transplant.

Part of a living adult donors liver can also be used for transplantation. Healthy liver tissue grows quickly; therefore, if an infant receives part of a liver from a living donor, both the donor and the infant can grow complete livers over time.

Infants with fetal biliary atresia are more likely to need a liver transplantand usually soonerthan infants with the more common perinatal form. The extent of damage can also influence how soon an infant will need a liver transplant. </s>

After the Kasai procedure, some infants continue to have liver problems and, even with the return of bile flow, some infants develop cirrhosis. Possible complications after the Kasai procedure include ascites, bacterial cholangitis, portal hypertension, and pruritus.

Ascites. Problems with liver function can cause fluid to build up in the abdomen, called ascites. Ascites can lead to spontaneous bacterial peritonitis, a serious infection that requires immediate medical attention. Ascites usually only lasts a few weeks. If ascites lasts more than 6 weeks, cirrhosis is likely present and the infant will probably need a liver transplant.

Bacterial cholangitis. Bacterial cholangitis is an infection of the bile ducts that is treated with bacteria-fighting medications called antibiotics.

Portal hypertension. The portal vein carries blood from the stomach, intestines, spleen, gallbladder, and pancreas to the liver. In cirrhosis, scar tissue partially blocks and slows the normal flow of blood, which increases the pressure in the portal vein. This condition is called portal hypertension. Portal hypertension can cause gastrointestinal bleeding that may require surgery and an eventual liver transplant.

Pruritus. Pruritus is caused by bile buildup in the blood and irritation of nerve endings in the skin. Prescription medication may be recommended for pruritus, including resins that bind bile in the intestines and antihistamines that decrease the skins sensation of itching. </s>


Input: What to do for Biliary Atresia ?

Output:
Infants with biliary atresia often have nutritional deficiencies and require special diets as they grow up. They may need a higher calorie diet, because biliary atresia leads to a faster metabolism. The disease also prevents them from digesting fats and can lead to protein and vitamin deficiencies. Vitamin supplements may be recommended, along with adding medium-chain triglyceride oil to foods, liquids, and infant formula. The oil adds calories and is easier to digest without bile than other types of fats. If an infant or child is too sick to eat, a feeding tube may be recommended to provide high-calorie liquid meals.

After a liver transplant, most infants and children can go back to their usual diet. Vitamin supplements may still be needed because the medications used to keep the body from rejecting the new liver can affect calcium and magnesium levels. </s>


Input: What to do for Biliary Atresia ?

Output: - Biliary atresia is a life-threatening condition in infants in which the bile ducts inside or outside the liver do not have normal openings.  - The first symptom of biliary atresia is jaundicewhen the skin and whites of the eyes turn yellow. Other symptoms include dark urine, gray or white stools, and slow weight gain and growth.  - Biliary atresia likely has multiple causes, though none is yet proven.  - No single test can definitively diagnose biliary atresia, so a series of tests is needed, including a blood test, abdominal x ray, ultrasound, liver scans, liver biopsy, and diagnostic surgery.  - Initial treatment for biliary atresia is usually the Kasai procedure, an operation where the bile ducts are removed and a loop of intestine is brought up to replace them.  - The definitive treatment for biliary atresia is liver transplant.  - After a liver transplant, a regimen of medications is used to prevent the immune system from rejecting the new liver. Health care providers may also prescribe blood pressure medications and antibiotics, along with special diets and vitamin supplements. </s>


Input: What is (are) Pyelonephritis: Kidney Infection ?

Output: Pyelonephritis is a type of urinary tract infection (UTI) that affects one or both kidneys. </s>


Input: What is (are) Pyelonephritis: Kidney Infection ?

Output: The urinary tract is the bodys drainage system for removing wastes and extra water. The urinary tract includes two kidneys, two ureters, a bladder, and a urethra. The kidneys are two bean-shaped organs, each about the size of a fist. They are located near the middle of the back, just below the rib cage, one on each side of the spine. Every day, the two kidneys process about 200 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra water. Children produce less urine than adults. The amount produced depends on their age. The urine flows from the kidneys to the bladder through tubes called the ureters. The bladder stores urine until releasing it through urination. When the bladder empties, urine flows out of the body through a tube called the urethra at the bottom of the bladder. </s>


Input: What causes Pyelonephritis: Kidney Infection ?

Output: Pyelonephritis is caused by a bacterium or virus infecting the kidneys. Though many bacteria and viruses can cause pyelonephritis, the bacterium Escherichia coli is often the cause. Bacteria and viruses can move to the kidneys from the bladder or can be carried through the bloodstream from other parts of the body. A UTI in the bladder that does not move to the kidneys is called cystitis. </s>


Input: Who is at risk for Pyelonephritis: Kidney Infection? ?

Output: People most at risk for pyelonephritis are those who have a bladder infection and those with a structural, or anatomic, problem in the urinary tract. Urine normally flows only in one directionfrom the kidneys to the bladder. However, the flow of urine may be blocked in people with a structural defect of the urinary tract, a kidney stone, or an enlarged prostatethe walnut-shaped gland in men that surrounds the urethra at the neck of the bladder and supplies fluid that goes into semen. Urine can also back up, or reflux, into one or both kidneys. This problem, which is called vesicoureteral reflux (VUR), happens when the valve mechanism that normally prevents backward flow of urine is not working properly. VUR is most commonly diagnosed during childhood. Pregnant women and people with diabetes or a weakened immune system are also at increased risk of pyelonephritis. </s>


Input: What are the symptoms of Pyelonephritis: Kidney Infection ?

Output:
Symptoms of pyelonephritis can vary depending on a persons age and may include the following:

- fever  - vomiting  - back, side, and groin pain  - chills  - nausea  - frequent, painful urination

Children younger than 2 years old may only have a high fever without symptoms related to the urinary tract. Older people may not have any symptoms related to the urinary tract either; instead, they may exhibit confusion, disordered speech, or hallucinations. </s>


Input: What are the complications of Pyelonephritis: Kidney Infection ?

Output:
Most people with pyelonephritis do not have complications if appropriately treated with bacteria-fighting medications called antibiotics.

In rare cases, pyelonephritis may cause permanent kidney scars, which can lead to chronic kidney disease, high blood pressure, and kidney failure. These problems usually occur in people with a structural problem in the urinary tract, kidney disease from other causes, or repeated episodes of pyelonephritis.

Infection in the kidneys may spread to the bloodstreama serious condition called sepsisthough this is also uncommon. </s>


Input: How to diagnose Pyelonephritis: Kidney Infection ?

Output:
The tests used to diagnose pyelonephritis depend on the patients age, gender, and response to treatment and include the following:

- Urinalysis. Urinalysis is testing of a urine sample. The urine sample is collected in a special container in a health care providers office or commercial facility and can be tested in the same location or sent to a lab for analysis. The presence of white blood cells and bacteria in the urine indicate infection.  - Urine culture. A urine culture is performed by placing part of a urine sample in a tube or dish with a substance that encourages any bacteria present to grow. The urine sample is collected in a special container in a health care providers office or commercial facility and sent to a lab for culture. Once the bacteria have multiplied, which usually takes 1 to 3 days, they can be identified. The health care provider can then determine the best treatment.  - Ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging; anesthesia is not needed. The images can show obstructions in the urinary tract. Ultrasound is often used for people who do not respond to treatment within 72 hours.  - Computerized tomography (CT) scan. CT scans use a combination of x rays and computer technology to create three-dimensional (3-D) images. A CT scan may include the injection of a special dye, called contrast medium. CT scans require the person to lie on a table that slides into a tunnel-shaped device where the x rays are taken. The procedure is performed in an outpatient center or hospital by an x-ray technician, and the images are interpreted by a radiologist. Anesthesia is not needed. CT scans can show obstructions in the urinary tract. The test is often used for people who do not respond to treatment within 72 hours.  - Voiding cystourethrogram (VCUG). A VCUG is an x-ray image of the bladder and urethra taken while the bladder is full and during urination, also called voiding. The procedure is performed in an outpatient center or hospital by an x-ray technician supervised by a radiologist, who then interprets the images. Anesthesia is not needed, but sedation may be used for some people. The bladder and urethra are filled with contrast medium to make the structures clearly visible on the x-ray images. The x-ray machine captures images of the contrast medium while the bladder is full and when the person urinates. This test can show abnormalities of the inside of the urethra and bladder and is usually used to detect VUR in children.  - Digital rectal examination (DRE). A DRE is a physical exam of the prostate that is performed in the health care providers office. Anesthesia is not needed. To perform the exam, the health care provider asks the person to bend over a table or lie on his side while holding his knees close to his chest. The health care provider slides a gloved, lubricated finger into the rectum and feels the part of the prostate that lies in front of the rectum. Men with suspected pyelonephritis may have a DRE to determine whether a swollen prostate may be obstructing the neck of the bladder.  - Dimercaptosuccinic acid (DMSA) scintigraphy. DMSA scintigraphy is an imaging technique that relies on the detection of small amounts of radiation after injection of radioactive material. Because the dose of radioactive material is small, the risk of causing damage to cells is low. The procedure is performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologist. Anesthesia is not needed. Radioactive material is injected into a vein in the persons arm and travels through the body to the kidneys. Special cameras and computers are used to create images of the radioactive material as it passes through the kidneys. The radioactive material makes the parts of the kidney that are infected or scarred stand out on the image. DMSA scintigraphy is used to show the severity of kidney infection or kidney damage, such as scarring. </s>


Input: What are the treatments for Pyelonephritis: Kidney Infection ?

Output:
Pyelonephritis is treated with antibiotics, which may need to be taken for several weeks. While a urine sample is sent to a lab for culture, the health care provider may begin treatment with an antibiotic that fights the most common types of bacteria. Once culture results are known and the bacteria is clearly identified, the health care provider may switch the antibiotic to one that more effectively targets the bacteria. Antibiotics may be given through a vein, orally, or both. Urinary tract obstructions are often treated with surgery.

Severely ill patients may be hospitalized and limited to bed rest until they can take the fluids and medications they need on their own. Fluids and medications may be given intravenously during this time.

In adults, repeat urine cultures should be performed after treatment has ended to make sure the infection does not recur. If a repeat test shows infection, another 14-day course of antibiotics is prescribed; if infection recurs again, antibiotics are prescribed for 6 weeks. </s>

Input: What is (are) Primary Sclerosing Cholangitis ?

Output:
PSC is a disease that damages and blocks bile ducts inside and outside the liver. Bile is a liquid made in the liver. Bile ducts are tubes that carry bile out of the liver to the gallbladder and small intestine. In the intestine, bile helps break down fat in food.

In PSC, inflammation of the bile ducts leads to scar formation and narrowing of the ducts over time. As scarring increases, the ducts become blocked. As a result, bile builds up in the liver and damages liver cells. Eventually, scar tissue can spread throughout the liver, causing cirrhosis and liver failure. </s>


Input: What causes Primary Sclerosing Cholangitis ?

Output:
The causes of PSC are not known. Genes, immune system problems, bacteria, and viruses may play roles in the development of the disease.

PSC is linked to inflammatory bowel disease (IBD). About three out of four people with PSC have a type of IBD called ulcerative colitis. The link between PSC and IBD is not yet understood. </s>


Input: Who is at risk for Primary Sclerosing Cholangitis? ?

Output: Most people with PSC are adults but the disease also occurs in children. The average age at diagnosis is 40. PSC is more common in men than women. Having family members with PSC may increase a person's risk for developing PSC. </s>


Input: What are the symptoms of Primary Sclerosing Cholangitis ?

Output: The main symptoms of PSC are itching, fatigue, and yellowing of the skin or whites of the eyes. An infection in the bile ducts can cause chills and fever. PSC progresses slowly, so a person can have the disease for years before symptoms develop. </s>


Input: What are the complications of Primary Sclerosing Cholangitis ?

Output:
PSC can lead to various complications, including

- deficiencies of vitamins A, D, E, and K  - infections of the bile ducts  - cirrhosisextensive scarring of the liver  - liver failure  - bile duct cancer </s>


Input: How to diagnose Primary Sclerosing Cholangitis ?

Output:
Blood tests to check levels of liver enzymes are the first step in diagnosing PSC. Doctors confirm the diagnosis using cholangiography, which provides pictures of the bile ducts.

Cholangiography can be performed in the following ways:

-  Endoscopic retrograde cholangiopancreatography (ERCP). ERCP uses an endoscopea long, flexible, lighted tubethat goes down the mouth, beyond the stomach, and into the duodenum to reach an area in the digestive tract where dye can be injected into the bile ducts. X rays are taken when the dye is injected. ERCP also can be used to take a tissue sample or to treat blocked ducts. More information about ERCP is provided in the NIDDK health topic, ERCP (Endoscopic Retrograde Cholangiopancreatography).  -  Percutaneous transhepatic cholangiography. This procedure involves inserting a needle through the skin and placing a thin tube into a duct in the liver. Dye is injected through the tube and x rays are taken.  -  Magnetic resonance cholangiopancreatography (MRCP). MRCP uses magnetic resonance imaging (MRI) to obtain pictures of the bile ducts. MRI machines use radio waves and magnets to scan internal organs and tissues. MRCP does not involve using x rays or inserting instruments into the body. This safe and painless test is increasingly used for diagnosis.

Other testing may include ultrasound exams and a liver biopsy. Ultrasound uses sound waves to create images of organs inside the body. A biopsy involves removal of a small piece of tissue for examination with a microscope. </s>


Input: What are the treatments for Primary Sclerosing Cholangitis ?

Output:
Although researchers have studied many treatments, none has been shown to cure or slow the progress of PSC. Treatment of PSC aims to relieve symptoms and manage complications. Medical treatment may include various medications to relieve itching, antibiotics to treat infections, and vitamin supplements. Instruments passed through an endoscope during ERCP can help open blocked bile ducts.

Liver transplantation may be an option if the liver begins to fail. </s>

Input: What is (are) Kidney Failure: Eat Right to Feel Right on Hemodialysis ?

Output:
You already know you need to watch how much you drink. Any food that is liquid at room temperature also contains water. These foods include soup, Jell-O, and ice cream. Many fruits and vegetables contain lots of water, too. They include melons, grapes, apples, oranges, tomatoes, lettuce, and celery. All these foods add to your fluid intake.

Fluid can build up between dialysis sessions, causing swelling and weight gain. The extra fluid affects your blood pressure and can make your heart work harder. You could have serious heart trouble from overloading your system with fluid.

Control Your Thirst   The best way to reduce fluid intake is to reduce thirst caused by the salt you eat. Avoid salty foods like chips and pretzels. Choose low-sodium products.   You can keep your fluids down by drinking from smaller cups or glasses. Freeze juice in an ice cube tray and eat it like a popsicle. (Remember to count the popsicle in your fluid allowance!) The dietitian will be able to give you other tips for managing your thirst.

Your dry weight is your weight after a dialysis session when all of the extra fluid in your body has been removed. If you let too much fluid build up between sessions, it is harder to get down to your proper dry weight. Your dry weight may change over a period of 3 to 6 weeks. Talk with your doctor regularly about what your dry weight should be.

My dry weight should be _____________.

Talk With a Dietitian   Even though you are on hemodialysis, your kidneys may still be able to remove some fluid. Or your kidneys may not remove any fluid at all. That is why every patient has a different daily allowance for fluid. Talk with your dietitian about how much fluid you can have each day.   I can have _____ ounces of fluid each day.
