What is Duodenal Switch Surgery?
Duodenal switch surgery, also called Biliopancreatic Diversion with Duodenal Switch or Gastric Reduction Duodenal Switch, is a weight loss surgery.
The Duodenal switch procedure involves a restrictive aspect and a malabsorptive aspect. The restrictive aspect limits food intake by reducing stomach size and the malabsorptive aspect means fat absorption is reduced by making your food bypass part of the small intestine, resulting in fewer calories and weight loss.

Who is a suitable candidate for the Duodenal Switch Surgery?
