This is the portion of the stomach that was removed during a laparoscopic sleeve gastrectomy, a type of bariatric (surgical weight loss) procedure. About 75% of the stomach was removed by a surgical resection of a large portion of the stomach along the greater curvature, leaving a narrow gastric “tube” or “sleeve”. No intestines are removed or bypassed during the sleeve gastrectomy. The basic principle behind that procedure is that it greatly reduces the size of the stomach and limits the amount of food that can be eaten at one time.
The newly created stomach is considerably smaller and facilitates significantly smaller meals, which translates into less calories consumed.
Removing a portion of the stomach reduces the body’s level of a hormone called ghrelin, which is commonly referred to as the “hunger hormone.” That promotes satiety, suppress hunger, and reverse one of the primary mechanisms by which obesity induces type 2 diabetes.
