Duodenal Switch

Duodenal switch (DS) or gastric reduction duodenal switch (GRDS), is a weight loss surgery procedure that involves removing approximately 70% of the stomach along the greater curvature.

This surgery reroutes a lengthy portion of the small intestine creating two separate pathways and one common channel. The shorter of the two pathways, takes food from the stomach to the common channel. The much longer pathway, carries bile from the liver to the common channel.
