Bariatric surgery

Gastric bypass and other weight-loss surgeries make changes to your digestive system to help you lose weight by limiting how much you can eat or by reducing the absorption of nutrients, or both. Gastric bypass and other weight-loss surgeries are done when diet and exercise haven't worked or when you have serious health problems because of your weight. There are many types of weight-loss surgery, known collectively as bariatric surgery. Many surgeons prefer gastric bypass surgery because it generally has fewer complications than do other weight-loss surgeries. Still, all forms of weight-loss surgery, including gastric bypass, are major procedures that can pose serious risks and side effects.
