The American Diabetes Association (ADA) since 2003 uses a slightly different range for impaired fasting glucose of 5.6 to 6.9 mmol/L (100 to 125 mg/dL).Glycated hemoglobin is better than fasting glucose for determining risks of cardiovascular disease and death from any cause. Prevention
There is no known preventive measure for type 1 diabetes. Type 2 diabetes—which accounts for 85–90% of all cases worldwide—can often be prevented or delayed by maintaining a normal body weight, engaging in physical activity, and eating a healthy diet. Higher levels of physical activity (more than 90 minutes per day) reduce the risk of diabetes by 28%. Dietary changes known to be effective in helping to prevent diabetes include maintaining a diet rich in whole grains and fiber, and choosing good fats, such as the polyunsaturated fats found in nuts, vegetable oils, and fish. Limiting sugary beverages and eating less red meat and other sources of saturated fat can also help prevent diabetes. Tobacco smoking is also associated with an increased risk of diabetes and its complications, so smoking cessation can be an important preventive measure as well.The relationship between type 2 diabetes and the main modifiable risk factors (excess weight, unhealthy diet, physical inactivity and tobacco use) is similar in all regions of the world. There is growing evidence that the underlying determinants of diabetes are a reflection of the major forces driving social, economic and cultural change: globalization, urbanization, population aging, and the general health policy environment.
However, these subgroups do not affect how the disease is diagnosed or treated. Treatment
Prostaglandins
If the diagnosis is made prenatally, prostaglandin E1 (PGE1) is started after birth to avoid closure of the ductus arteriosus. Prostaglandin therapy is performed via a continuous infusion, due to how quickly prostaglandins are metabolized in the body. However, the diagnosis may go undetected, delaying treatment until closure of the ductus arteriosus produces symptoms. Surgery
Curative treatment consists of open heart surgery soon after birth, preferably immediately after diagnosis. Often, a synthetic patch is used to recreate the lost section of aorta. Recent research has revealed that an initial single-stage repair using direct anastomoses and repair of any existing cardiac defects is the preferred surgical technique, as opposed to a two-stage surgical repair.Awaiting surgery, prostaglandin can be administered to keep the ductus arteriosus open, thereby allowing blood flow to the lower body. After successful treatment, the patient is monitored for the rest of their life by a specialist to ensure that problems do not occur. Prognosis
Failure to treat the condition yields a mortality rate of 90% at a median age of 4 days. Death occurs due to increased blood flow from the left side of the heart (oxygenated blood) to the right side (deoxygenated blood), inducing heart failure; pulmonary edema; and eventual closing of the ductus arteriosus. For an infant with an interrupted aortic arch, a patent (open) ductus arteriosus allows for blood to bypass the "interruption," without which blood will be unable to reach the lower half of the body.
