"The Duodenal Switch (DS) is a highly effective, two-step bariatric surgery designed for maximum weight loss and metabolic health. First, we remove a portion of the stomach to create a smaller 'sleeve,' reducing the amount of food you can eat (restriction). Second, we reroute a significant portion of your small intestine to limit the calories and fats your body absorbs (malabsorption). As the #1 recognized surgeon worldwide for this procedure by IFSO, I highly recommend the DS for patients seeking powerful, long-term weight loss and resolution of conditions like severe Type 2 Diabetes

The Duodenal Switch is the gold standard for significant, long-term weight loss, but it requires a lifelong commitment to your health and nutrition. It is typically the ideal choice for patients with a BMI of 50 or higher, or those struggling with severe obesity-related conditions like uncontrolled Type 2 Diabetes, sleep apnea, or high cholesterol. Because it offers the highest metabolic impact, itβs also an excellent option for revision surgery. As the world's most experienced DS surgeon, I will personally evaluate your unique medical history during our consultation to ensure this powerful procedure is your safest and most effective path to a new life.
In this video, I explain the SADI-S, a highly advanced and modern evolution of the traditional Duodenal Switch. While a standard Duodenal Switch involves two intestinal connections, the SADI-S simplifies this into a single loop (Single Anastomosis). It powerfully combines a gastric sleeve to restrict food intake with an intestinal bypass to reduce calorie absorption. As the world's leading expert in this procedure, I break down exactly how this dual-action surgery delivers maximum weight loss and metabolic healing with an even safer, streamlined technique.
