Mini gastric bypass
Mini gastric bypass Treatment
Mini gastric bypass (also called one-anastomosis gastric bypass) is a type of bariatric surgery used for weight loss. In this procedure, the stomach is made smaller and connected directly to a part of the small intestine, reducing both food intake and calorie absorption. It is simpler and quicker than traditional gastric bypass.
