Laparoscopic Roux-en-Y Gastric Bypass
Gastric bypass surgery makes the stomach smaller and causes food to bypass part of the small intestine. You will feel full more quickly than when your stomach was its original size. This reduces the amount of food you can eat at one time. Bypassing part of the intestine reduces how much food and nutrients are absorbed. This leads to weight loss. One type of gastric bypass surgery is a Roux-en-Y gastric bypass.
