Roux-en-Y gastric bypass surgery for weight loss. The procedure reduces the stomach to a small pouch, bypasses the duodenum and part of the small intestine, and alters gut hormone signals. It is performed laparoscopically using keyhole surgery. Patients may be considered for surgery with a BMI of 30 or over, following review of lifestyle, psychological and obesity-related health factors. Post-surgery dietary and lifestyle changes are required, with nutritionist or dietitian support recommended. Potential risks include dumping syndrome, leaks, nutritional deficiencies, strictures or blockages, ulcers and weight regain.
