Duodenal Switch is a bariatric surgery that combines a sleeve gastrectomy (removal of a portion of the stomach) with an intestinal bypass. The procedure involves creating a small stomach pouch and rerouting the small intestine to limit calorie absorption and promote significant weight loss.

This surgery is particularly effective for patients with severe obesity and metabolic conditions like type 2 diabetes. The duodenal switch not only promotes weight loss but also has the added benefit of improving metabolic function by affecting nutrient absorption.

Postoperative care includes a strict diet, vitamin supplementation, and regular monitoring of nutritional health. Patients need to avoid high-fat foods to prevent dumping syndrome, a common complication of this surgery.

The duodenal switch is highly effective for long-term weight loss and improving comorbid conditions but requires ongoing medical supervision to manage potential nutritional deficiencies.
