Gastric bypass surgery is performed in most cases on people in danger of severe health problems related to obesity. The surgery makes the stomach smaller, making the person feel full quicker after eating, thus reducing the amount of food consumed. The procedure also allows food to bypass part of the intestine, causing fewer calories to be absorbed.
Common side effects of gastric bypass surgery include:
- Infection from the incision
- Leaking from the stomach into the abdominal cavity
- Blood clots
