Laparoscopic Sleeve Gastrectomy is a weight loss surgery method used mainly to remove part of the stomach along the greater curvature, thus reducing the size of the stomach substantially. It is the most commonly performed procedure worldwide today.
As the name suggests, the procedure is performed laparoscopically and a major portion of the stomach is removed leaving a narrow gastric tube (sleeve) behind. The reduction in the size of the stomach limits the amount of food intake and brings about decreased appetite without affecting the ability of the body to absorb the nutrients from the food consumed and without affecting the usual functioning of the intestines. It is mainly a restrictive procedure with hormonal alterations. There is a decrease in the levels of hormone Ghrelin which produces hunger. One remains comfortable despite eating less and looses weight and related illness.
