The stomach removal that occurs as part of the sleeve gastrectomy procedure aids weight loss in two ways: the remaining sleeve holds significantly less food, and by removing much of the stomach, surgeons are also removing the source for a hormone, Ghrelin, that is responsible for hunger. Sleeve gastrectomy patients experience less hunger and feel full more quickly.

Sleeve Gastrectomy Results

Along with making changes to diet and incorporating exercise, most sleeve gastrectomy patients lose 30 to 50 percent of their excess body weight within a year of the sleeve gastrectomy procedure.
