Biliopancreatic Diversion with Duodenal Switch
A biliopancreatic diversion changes the normal digestive process by making the stomach smaller. It allows food to bypass part of the small intestine so that you absorb fewer calories. Because of the risks, this surgery is performed only on individuals who are severely obese (BMI of 50 or more).
After surgery, you will feel full more quickly, reducing the amount of food you’ll want to eat. Bypassing part of the intestine also means you’ll absorb fewer calories.
In a biliopancreatic diversion with duodenal switch, a small part of the stomach is removed while the remaining stomach stays attached to the duodenum (the upper part of the small intestine). This is a high-risk surgery that can cause long-term health problems because your body has a harder time absorbing food and nutrients.
