Roux-en-Y gastric bypass is a bariatric surgery that creates a small gastric pouch (typically 15-30ml) and bypasses most of the stomach and proximal small intestine. The procedure has two mechanisms: restriction (small pouch reduces meal volume) and malabsorption (bypassed proximal small bowel reduces nutrient absorption). RYGB produces typically greater weight loss than sleeve gastrectomy in many series, better resolution of type 2 diabetes and reflux disease, and a more durable long-term result — at the cost of technical complexity, higher early-complication rate, more demanding lifelong nutritional supplementation, and a small ongoing risk of internal hernia.
View Roux-en-Y Gastric Bypass pageBariatric surgery is a group of surgical procedures used to manage obesity and related conditions. Long-term weight loss with bariatric surgery may be achieved through alteration of gut hormones, physical reduction of stomach size, reduction of nutrient absorption, or a combination of these.
