Roux-en-Y Gastric Bypass
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). Randomised trials show weight loss broadly similar to sleeve gastrectomy, with no clear difference in diabetes outcomes and reflux improving after bypass in one trial — at the cost of technical complexity, a higher early-complication rate in some series, more demanding lifelong nutritional supplementation, and a small ongoing risk of internal hernia.

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.
