Risks of Gastric Banding Surgery

All surgical procedures have risks, and they are real, but the risk of serious complications from gastric banding is quite low. The risk of complications following gastric band surgery is similar to the risks following any major surgery on your digestive tract. Morbidly obese patients face added risks because of their body size.
