Take control of your health and transform your life with duodenal switch surgery, including the SADI-S procedure. These powerful bariatric surgeries not only limit how much you can eat—they also reduce how much fat and calories your body absorbs. The result is dramatic, long-term weight loss that can help resolve obesity-related health conditions and significantly improve your quality of life.
The duodenal switch, also known as biliopancreatic diversion with duodenal switch (BPD/DS), is a two-part bariatric surgery that combines restrictive and malabsorptive techniques. This means it helps reduce hunger and food intake while also limiting the number of calories absorbed by the body.
A simplified and increasingly popular variation of this surgery is called SADI-S (Single Anastomosis Duodeno–Ileal Bypass with Sleeve Gastrectomy). SADI-S involves similar principles but uses only one surgical connection (anastomosis) in the small intestine, making it less complex and potentially reducing the risk of complications compared to the traditional duodenal switch.
Duodenal switch and SADI-S surgeries support weight loss by:
In both procedures, a sleeve gastrectomy is performed to remove a large portion of the stomach, creating a banana-shaped pouch. In the traditional duodenal switch, the small intestine is rearranged to separate the flow of food from digestive enzymes through two separate connections. In SADI-S, there is only one connection, streamlining the process while still achieving significant malabsorption and weight loss.
These surgeries are especially effective for individuals with severe obesity (BMI over 50) or those who have not achieved significant weight loss with other procedures. They are also recommended for patients with serious obesity-related conditions, such as:
Both the traditional duodenal switch and SADI-S are among the most effective bariatric surgeries in producing long-term weight loss and remission of type-2 diabetes, often making them the best options for high-risk individuals.
These procedures are typically performed laparoscopically, which allows for fewer complications, smaller incisions, and a faster recovery time compared to open surgery.
Because of the changes in nutrient absorption, patients will need to commit to lifelong vitamin supplementation and regular follow-ups to ensure proper nutrition. Working with your weight loss surgeon and support team is essential to maintaining a healthy lifestyle after surgery.
Duodenal switch and SADI-S offer long-lasting solutions to obesity, often resulting in more significant weight loss than other bariatric procedures, especially in individuals with a higher BMI.
