Lower abdominal mass in a neonate or child

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.
