Biliopancreatic Diversion


Biliopancreatic diversion (BPD) is an aggressive form of metabolic surgery intended for individuals who are severely obese and/or suffering from type 2 diabetes and other obesity-related illnesses. When performed on its own, without the duodenal switch (DS), BPD is a malabsorptive surgery: it works by limiting the amount of energy the body can absorb from the food you eat. When BPD is performed in conjunction with the duodenal switch (BPD/DS), it is a combination malabsorptive/restrictive procedure that both limits your food intake and the amount of energy your body can absorb. Both BPD and BPD/DS are associated with rapid, significant weight loss. Moreover, this procedure has been shown to produce an extremely rapid improvement of obesity-related health problems like type 2 diabetes, often in advance of significant weight loss.*

In many cases, BPD/DS can be performed laparoscopically, greatly improving its record of safety and effectiveness in recent years. The application of cutting-edge surgical techniques, coupled with aggressive weight loss results and immediate impact on obesity-related health problems, means that BPD/DS is an excellent option for many patients when it is performed by a highly-trained surgeon with years of experience performing metabolic surgeries. As lead surgeon at The Center for Metabolic and Obesity Surgery in Altamonte Springs, Florida, Dr. Wiljon Beltre is a fellowship-trained, Board Certified surgeon who has the years of experience and the commitment to staying abreast of the latest developments in metabolic surgery needed to make your surgery as safe and effective as possible. Moreover, his comprehensive, holistic approach to weight loss and warm, compassionate team of weight loss experts will help you find the strength to lose the weight you want and keep it off, enabling you to take control of your health, your well-being, and your self-confidence!


A biliopancreatic diversion (BPD) alters the way in which your food passes through the digestive tract to decrease your body’s ability to absorb calories. During a BPD, the lower two-thirds of the stomach, including the pylorus valve that separates the stomach from the duodenum (the upper part of the small intestine where the majority of digestion normally occurs) is removed. The remaining “pouch”, which can hold about two to three cups of chewed food, is reconnected to the small intestine much further down into the digestive tract, bypassing the duodenum and about nine feet of small intestine. Enzymes and bile from the liver and pancreas that help your body digest the food enter the small intestine much closer to the colon to minimize their impact on digestion. This procedure decreases the size of the stomach and bypasses a significant portion of the small intestine.

A BPD can be performed as a stand-alone operation, or in conjunction with a duodenal switch (BPD/DS). During a BPD/DS, the left side of the stomach is removed (instead of the lower portion as in a stand-alone BPD), preserving the pylorus valve and more effectively restricting the size of the stomach to limit food intake. The small intestine is cut below the duodenum and reattached at a much lower point in the intestine, shortening the distance through which the food passes between the duodenum and the colon. The remaining intestine is used to enable the passage of enzymes and bile from the liver and pancreas into the lower section of intestine to facilitate digestion.

If BPD is performed without a DS, portion size can be greater but the risk of “dumping syndrome” is higher as well, while BPD/DS requires strict adherence to a regimented diet and changes in eating habits, but involves less risk of ulcers and dumping syndrome. Because both procedures are malabsorptive, they have a high risk of nutritional and vitamin deficiencies and a life-time commitment to regular vitamin supplements and a strict, high-protein, low-fat diet is required. Moreover, because the body will have a difficult time processing fat, common side effects are frequent, loose bowel movements and diarrhea, gas and flatulence, and bloating. During your initial consultation, Dr. Beltre will review all of the advantages and disadvantages of both procedures, as well as the surgical risks common to any surgical procedure, to help you understand which option is best suited to give you the greatest possible chance to finally achieve the weight loss success for which you have worked so hard.
