Sewing the small stomach together is known as "stomach stapling," notes WebMD. The surgeon then detaches the small stomach from the first portion of the small intestine and moves it farther down. Doing so prevents the absorption of calories and enhances weight loss, which is also known as "malabsorptive." The small stomach pouch only holds around a cup of food at most. Patients who undergo gastric bypass surgery lose 60 percent of their excess weight. Many aliments associated with being obese or overweight dissipate or improve over time. Some of these diseases include diabetes, high blood pressure, sleep apnea and asthma. However, patients need to maintain a healthy lifestyle to keep off the weight.

The procedure is usually prescribed for patients who suffer from hypertension or Type 2 diabetes, claims Wikipedia. Those who are morbidly obese also qualify for gastric bypass surgery. WebMD adds that complications from the procedure include ulcers, bleeding, infections and digestive problems, but these side effects are considered minor. A small number of people may experience serious complications in the form of blood clots or heart attacks.
