Procedures
Duodenal Switch
A combined restrictive and malabsorptive bariatric procedure that produces the greatest weight loss among all surgical options for severe obesity.
PLAIN ENGLISH
Patient-Friendly Explanation
The duodenal switch is a weight loss surgery that combines stomach reduction with intestinal rerouting. It reduces how much you can eat and how many calories your body absorbs, making it one of the most effective bariatric procedures for severe obesity.
MEDICAL
Clinical Definition
Biliopancreatic diversion with duodenal switch (BPD-DS) involves a sleeve gastrectomy plus a long intestinal bypass that creates significant malabsorption. It produces the greatest average excess weight loss (70–80%) among bariatric procedures and has the highest remission rates for type 2 diabetes. However, it carries a higher risk of nutritional deficiencies — including fat-soluble vitamins, iron, and calcium — requiring lifelong supplementation and monitoring.
KEY INSIGHT
Why It Matters
While the duodenal switch is the most powerful bariatric option, it requires careful patient selection. Dr. Joseph Wang evaluates all surgical and medical options to find the best approach for your specific health needs.
