BPD/DS: Biliopancreatic Diversion with Duodenal Switch

The biliopancreatic diversion with duodenal switch (BPD/DS) procedure combines a reduction in stomach size with a bypass of some of the small intestine. Therefore, you can eat less and absorb less of the food you eat.

Type of Procedure: Combination

It is a combination of gastric restrictive and malabsorptive procedures, and is highly-effective in causing significant weight loss. This is the most complex of the weight loss procedures. Part of the stomach is removed and food is routed around most of the intestines. This usually results in the largest loss: 70 to 90 percent of excess weight.

All malabsorptive procedures including BPD/DS procedures cause significant permanent changes to digestion. Patients will need to monitor vitamin and protein intakes carefully, and there will be changes in the elimination of waste. Patients can learn about these changes in detail at one of our free weight loss information sessions.

The BPD/DS procedure is perhaps the most effective form of weight loss surgery. The majority of people who have this surgery lose between 70 percent and 90 percent of their excess weight within five years. These patients often report great satisfaction with the result of their surgeries. Typically, they feel the digestive complications the BPD/BS procedure causes are minor compared to the active life their new weight provides.
