Duodenal Switch (BPD – DS) is a surgical procedure that can be performed by mini-invasive surgery. The procedure affects the food intake in the body and reduces the absorption of nutrients from the intestinal tract. The absorption of the nutrients is reduced as a larger part of the intestines is bypassed and is no longer in use. The volume of the stomach after BPD – DS is somewhat between 150 and 250 ml – out of which only 75 cm and 100 cm long is the intestinal tract that is active. Duodenal Switch Surgery reduces the size of the stomach through surgical vertical stapling, and is the best option for people with metabolic disease processes such as Diabetes, PCOS, Hypertension, Hypertriglyceridemia and Cardiovascular Disease.
