Biliopancreatic Diversion With Duodenal Switch (BPD/DS)

The Biliopancreatic Diversion with Duodenal Switch (BPD/DS) procedure combines a reduction in your stomach size with a bypass of some of your small intestine. The effect is that you can eat less, and absorb less from the food you do eat. It’s a combination gastric restrictive and malabsorptive procedure, and is highly effective in causing significant weight loss. This is the most complex of the weight loss procedures. Part of your stomach is removed and food is routed around most of the intestines. This usually results in the largest loss: 70-90% of excess weight.

All malabsorptive procedures including BPD/DS procedures cause significant permanent changes in your digestion. You’ll need to monitor your vitamin and protein intakes carefully, and there will be changes in your elimination of waste. You can learn about these changes in detail at one of our free Weight Loss Information Sessions.

On the plus side, the BPD/DS procedure is perhaps the most effective form of weight loss (bariatric) surgery. The majority of people who have this surgery lose between 70% and 90% of their excess weight within five years. These people 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.
