What Is Gastric Bypass? How Is It Performed? Gastric bypass is one of the surgical procedures used to treat obesity. During the operation, a small stomach pouch is created and the small intestine is rearranged, changing the route food takes through the digestive system. This allows patients to feel full with smaller portions and may lead to significant long-term weight loss. How Is Gastric Bypass Surgery Performed? The operation is usually performed laparoscopically (minimally invasively) under general anesthesia. A small pouch is created in the upper part of the stomach and connected to a section farther along the small intestine. As a result, food bypasses most of the stomach and the initial section of the small intestine. Who Is Eligible for Gastric Bypass?
