Weight Loss Surgery
Weight Loss Surgery Procedures
Bariatric surgical procedures cause weight loss by restricting the amount of food the stomach can hold, causing malabsorption of nutrients, or by a combination of both gastric restriction and malabsorption. Bariatric procedures also often cause hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery).
The most common bariatric surgery procedures are gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch. Each surgery has its own advantages and disadvantages.
Revision bariatric surgery is the repair, modification, or changing of any of the operations listed above. The most commonly performed revision is the conversion of the Lap-Band to a sleeve gastrectomy, or the sleeve to a gastric bypass.
