Gastric bypass, also simply known as “gastric bypass,” is the most common type of bariatric surgery in the United States.
The surgical procedure is designed to help obese patients, who failed at losing weight using other non-surgical options. The procedure is conducted in two phases as the surgeon begins by stapling the stomach to create a small pouch in the upper part of the organ. The surgeon will then connect the newly-created pouch to the middle of the small intestine.
The purpose of gastric bypass surgery is to transport food directly from the pouch to the middle of the small intestine, without passing through the other part of the stomach and the first part of the small intestine. The procedure increases satiety so that the patient feels full faster with smaller amounts of food. However, it is not always successful and there are cases of failed gastric bypass. Failure occurs either when patients experience severe side effects or when they are unable to lose weight.
