The Duodenal Switch (DS) is a weight loss surgery that combines stomach restriction and intestinal bypass to promote significant weight loss. It reduces the stomach size while rerouting the intestines to limit calorie absorption, making it one of the most effective procedures for severe obesity.
This surgery is ideal for patients with BMI over 50 or those with obesity-related conditions like diabetes, high cholesterol, and sleep apnea. DS leads to greater long-term weight loss than other bariatric procedures but requires lifelong nutritional management.
The procedure has two steps: sleeve gastrectomy, where about 70-80% of the stomach is removed, and intestinal bypass, which reroutes part of the small intestine to limit calorie absorption. This helps patients eat smaller portions while absorbing fewer fats and calories.
Since food bypasses most of the small intestine, digestion is altered to promote faster weight loss. However, due to reduced nutrient absorption, patients must take lifelong vitamins and follow a high-protein diet.
DS is recommended for individuals with a BMI of 50+ or severe obesity-related conditions like diabetes, hypertension, and sleep apnea, offering significant, long-term weight loss. It is especially beneficial for those who have struggled with traditional weight loss methods and need a more effective solution.
Candidates must commit to lifelong dietary changes, supplementation, and regular medical follow-ups to prevent nutrient deficiencies. Since DS alters digestion and absorption, a thorough evaluation is required to assess overall health, readiness for surgery, and long-term commitment to lifestyle adjustments for lasting success.
The Duodenal Switch (DS) is one of the most effective bariatric procedures, leading to 70-80% excess weight loss and long-term weight management. It significantly improves blood sugar levels, making it highly effective in type 2 diabetes remission. Many patients experience reduced dependence on diabetes medications or complete reversal of the condition.
Additionally, DS enhances cholesterol levels, lowers blood pressure, and improves heart health, reducing the risk of cardiovascular diseases. Patients also benefit from sustained appetite control, as hormonal changes help decrease hunger, making it easier to maintain weight loss.
Most patients recover within 2-3 weeks, with full weight loss results taking 12-24 months as the body adapts. The diet progresses from clear liquids to pureed and soft foods, eventually leading to solid meals, with a focus on lean protein for muscle retention.
Since DS reduces nutrient absorption, lifelong supplements are essential to prevent vitamin and mineral deficiencies. Regular exercise, hydration, and a protein-rich diet help maintain weight loss and prevent complications. Routine medical check-ups ensure long-term health and success.
