Roux-en-Y Gastric Bypass Was the initial surgery used to help people with weight loss
Roux-en-Y (pronounced “ROO-en-why”) gastric bypass surgery restricts food intake by creating a small pouch at the top of the stomach. The rest of the stomach stays in your body.
The formed pouch is then connected to a section of the small intestine, allowing food to bypass the lower stomach and the first two parts of the small intestine.
Most gastric bypasses are performed using laparoscopy, a minimally invasive surgical technique performed through very small incisions in the abdomen.
