Lactose intolerance is a common condition caused by a decreased ability to digest lactose, a sugar found in dairy products. Those affected vary in the amount of lactose they can tolerate before symptoms develop. Symptoms may include abdominal pain, bloating, diarrhea, flatulence, and nausea. These symptoms typically start thirty minutes to two hours after eating or drinking milk-based food. Their severity typically depends on the amount a person eats or drinks. Lactose intolerance does not cause damage to the gastrointestinal tract.Lactose intolerance is due to the lack of the enzyme lactase in the small intestines to break lactose down into glucose and galactose. There are four types: primary, secondary, developmental, and congenital. Primary lactose intolerance occurs as the amount of lactase declines as people age. Secondary lactose intolerance is due to injury to the small intestine. Such injury could be the result of infection, celiac disease, inflammatory bowel disease, or other diseases. Developmental lactose intolerance may occur in premature babies and usually improves over a short period of time. Congenital lactose intolerance is an extremely rare genetic disorder in which little or no lactase is made from birth. The onset of primary lactose intolerance, the most common type, is typically in late childhood or early adulthood, but prevalence increases with age.Diagnosis may be confirmed if symptoms resolve following eliminating lactose from the diet. Other supporting tests include a hydrogen breath test and a stool acidity test. Other conditions that may produce similar symptoms include irritable bowel syndrome, celiac disease, and inflammatory bowel disease.
Signs and symptoms
Most Bartholins cysts do not cause any symptoms, although some may cause pain during walking, sitting, or sexual intercourse (dyspareunia). They are usually between 1 and 4 cm, and are located just medial to the labia minora. Most Bartholins cysts only affect the left or the right side (unilateral). While small cysts are usually not painful, larger cysts can cause significant pain. Pathophysiology
A Bartholins gland cyst develops when the duct that drains the gland becomes blocked. Blockage may be caused by an infection or a mucus plug. The secretions from the Bartholins gland are retained, forming a cyst. Diagnosis
Other conditions that may present similarly include hidradenoma papilliferum, lipomas, epidermoid cysts and Skenes duct cysts, among others conditions. In women who are more than 40 years, a biopsy may be recommended to rule out cancer. Treatment
If the Bartholins cysts is not painful or uncomfortable, treatment may not be necessary. Small, asymptomatic cysts can be observed over time to assess their development. In cases that require intervention, a catheter may be placed to drain the cyst, or the cyst may be surgically opened to create a permanent pouch (marsupialization). Intervention has a success rate of 85%, regardless of the method used, to alleviate swelling and discomfort.Catheterization is a minor procedure that can be performed locally as an outpatient procedure. A small tube with a balloon on the end (known as a Word catheter) may be inserted into the cyst. The balloon is then inflated to keep it in place.
