Bariatric Surgery is a type of surgery done for weight loss in extremely obese people. Generally this surgery is done by modifying the normal size or pathway of the digestive system, especially the stomach. In the normal digestive system, the food goes into the stomach where it begins being digested, then passes to the small intestine (where nutrients are absorbed) then proceeds to the large intestine (where water is absorbed) then the waste products subsequently pass out of the bottom as stool. Duodenal switch (also known as Biliopancreatic Diversion with Pancreatic Switch) is a type of bariatric surgery that is similar to the very very long limb Roux-en-Y gastric bypass. Duodenal switch involves bypassing a large section of the small intestines (which absorbs food and nutrients) by connecting the end of the small intestine directly to the stomach. The duodenal switch leaves more of the stomach in place including the pyloric valve, which opens and closes to control the outlet of food into the small intestine. Due to bypassing a large section of the small intestine, this type of bariatric surgery runs the risk of nutrient deficiencies.
