Sleeve gastrectomy removes approximately 80% of the stomach laparoscopically, creating a tube-shaped stomach that restricts food intake and reduces hunger hormones. It is one of the most commonly performed bariatric procedures worldwide. The procedure is irreversible and requires lifelong dietary changes.
View Gastric Sleeve (Sleeve Gastrectomy) pageRoux-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.
