The duodenal switch, also known as biliopancreatic diversion with duodenal switch (BPD/DS), is a type of weight loss surgery that involves two main steps. The first is a sleeve gastrectomy, in which a large part of the stomach is removed to restrict food intake. The second is a rerouting of the intestines to reduce calorie absorption. This dual approach makes it one of the most effective bariatric surgeries for weight loss and resolution of comorbidities.
Success Rate: Most patients lose 70-80% of their excess weight within two years and maintain a significant weight loss of 60-70% at 10 years.
Recovery: Patients usually stay in the hospital for 2 to 3 days after the surgery. A full recovery usually takes 3 to 6 weeks, and adjustments to the new eating patterns may take several months.
