Duodenal Switch - SADIS-S
The Duodenal Switch weight loss surgery procedure is performed by only a small group of bariatric surgeons. Duodenal Switch is a more involved weight loss surgery procedure due to the significant malabsorptive and metabolic components. This is accomplished with the intestinal bypass effect of the Duodenal Switch. As a result, Duodenal Switch patients are able to engage in relatively normal and free eating while also adopting a metabolism similar to that of a lean individual.
For reference, Duodenal Switch is also referred to as SADIS-S (which stands for single anastomosis duodenal ileal switch & sleeve), vertical gastrectomy with duodenal switch, biliopancreatic diversion with duodenal switch, gastric reduction duodenal switch, DS, BPD-DS, or GR-DS.
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
