Duodenal Switch weight loss surgery procedures are performed by only a minority of bariatric surgeons. They are more complex procedures due to the combination of significant restriction from the sleeve portion and malabsorption from bypassing a significant amount of small intestine. In 2019, the Single Anastomosis Duodenal Switch -Sleeve (SADI-S) procedure was approved by the American Society of Metabolic and Bariatric Surgery as a primary weight loss surgery procedure. It works by similar principles as the traditional Duodenal Switch, but carries less nutritional risk. Consequently, it is quickly becoming a favored treatment option for our heavier patient population.
The Duodenal Switch causes weight loss via the following mechanisms:
- restricting the quantities of food that can be eaten by reducing stomach size
- rerouting the intestines limits the amount of food the body absorbs
- intestinal rerouting manipulates intestinal hormones and results in a significant metabolic effect
