Gastric bypass surgery is an operative procedure to reduce the size of the stomach and bypassing a part of small intestine. The reduction in the size of the stomach will make a person feel that their stomach is full more quickly than before the procedure. This will lead to an incredible reduction in the consumption of food by that person. The process of bypassing the small intestine will reduce the absorption of the calories into the body. The combination of these two procedures, i.e. the lesser intake of food and lesser absorption of food will lead to reduction of body weight of an obese person. Gastric bypass surgery is done only after ruling out all other methods of weight reduction.
