Gastric bypass is a surgical procedure that achieves rapid weight loss by ``rerouting'' digestion from the entire stomach to a smaller pouch, and from the upper intestine to the middle part of the small intestines. The most common form of this procedure is the Roux-en-Y bypass. The stomach pouch is created by stapling or placing an elastic band just below where the esophagus enters the stomach, and is then connected to the middle part of the small intestines. This procedure reduces the size of the stomach and bypasses portions of the digestive tract where most calories are processed and absorbed.
