Gastric Roux-en-Y Bypass

In this operation a small stomach pouch is created to restrict food intake. Next, the small intestine is reconfigured and attached to the pouch to allow food to bypass the lower stomach,the duodenum (the first segment of the small intestine) and the first portion of the jejunum (the second segment of the small intestine). This bypass reduces the absorption of food and thereby reduces the calorie intake.
