Bariatric surgery

Surgical procedure for management of obesity

Bariatric surgery (also known as metabolic surgery or weight loss surgery) is a group of surgical procedures used to manage obesity and related conditions. Long-term weight loss with bariatric surgery may be achieved through alteration of gut hormones, physical reduction of stomach size, reduction of nutrient absorption, or a combination of these. Standard of care procedures include Roux en-Y bypass, sleeve gastrectomy, and biliopancreatic diversion with duodenal switch, from which weight loss is largely achieved by altering gut hormone levels responsible for hunger and satiety, leading to a new hormonal weight set point.
