Gastric Bypass Surgery
Gastric Bypass is a major surgery aimed at drastic weight loss to treat morbid obesity which can bring about life-threatening health problems such as cardiovascular diseases, diabetes type 2, obstructive sleep apnea, diseases of the liver and gallbladder and degenerative diseases of the disc and weight-bearing joints. Although gastric bypass is a surgical procedure that is accompanied by significant risks and side effects and necessitates permanent changes to one's lifestyle, it can provide long-term, consistent weight loss and lower the risks of medical problems associated with obesity. The gastric bypass surgery, in its various forms, is designed to reduce the food intake of the patient and also prohibits the food from entering a part of the small intestine. The surgical procedure is extremely complex and performed under general anesthesia. The surgery is lengthy and can take up to four hours and patients can expect to stay in hospital for a week. The various procedures are performed through open surgery. Depending on the type of procedure either a long incision or multiple long incisions are made on the stomach. Fat, muscles and tissues are pulled back and the stomach lining divided and stapled to create a small upper pouch (to limit food intake) and a larger lower pouch. The surgeon then re-arranges the small intestine and connects both pouches to it. The bypasses of the small intestine are formed to decrease the absorption of food nutrients. After surgery, most people will require two to five weeks of recovery before they can return to their normal activities. The patient is put on a strict dietary program with vitamin supplements along with regular exercise. Weight loss can be seen quickly following the surgery and many people continue to lose weight for up to more than a year after surgery.
