The Duodenal Switch weight loss surgery procedure is performed by only a minority of bariatric surgeons. Duodenal Switch is a more involved weight loss surgery procedure do 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.
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
