The RNY both restricts food intake and interferes with absorption, resulting in more consistent weight loss. But because of the complexity, gastric bypass contains a higher risk of complications or side effects.


The complications of gastric bypass surgery are much less severe than those of intestinal bypass surgeries and are usually easily handled by a competent medical staff and patient compliance.

All surgical procedures have risks, and they are real. The risk of complications following gastric bypass 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.
