Bilio-pancreatic Diversion

Biliopancreatic diversion with duodenal switch (BPD/DS) is a complex malabsorptive procedure that combines sleeve gastrectomy with intestinal bypass. It involves removing about 80% of the stomach and rerouting the small intestine to significantly reduce nutrient absorption. BPD/DS results in the most substantial weight loss among bariatric procedures and has the highest rate of diabetes remission. However, it carries a higher risk of nutritional deficiencies and complications, requiring lifelong supplementation and close follow-up.
