Bariatric surgery, including gastric bypass, sleeve gastrectomy, and adjustable gastric banding, is a highly effective treatment for obesity and metabolic disorders. Minimally invasive and robotic-assisted approaches improve safety, reduce complications, and accelerate recovery. Preoperative evaluation, nutritional counseling, and postoperative support are critical for success. Ongoing innovations in surgical techniques, patient monitoring, and enhanced recovery protocols continue to optimize outcomes and quality of life for patients undergoing bariatric surgery.
