Bariatric surgery (or weight loss surgery) includes a variety of procedures performed on people who are obese. Long term weight loss through Standard of Care procedures (Roux en Y Bypass, Sleeve Gastrectomy, and Biliopancreatic Diversion with Duodenal Switch) is largely achieved by altering gut
hormone levels that are responsible for hunger and satiety, leading to a new hormonal weight set point.[1] Bariatric surgery is a hormonal surgery in these procedures, for which the alteration in gut
hormones develops as a result of the procedure's restriction and malabsorption.
