This surgery is performed by removing approximately 80 percent of the stomach. The remaining stomach looks like a banana or a sleeve of a shirt and is hence called a ‘ Sleeve ‘.

The new stomach pouch being much smaller restricts food intake thus leading to weight loss.

Sleeve gastrectomy causes favourable changes in gut hormones that suppress hunger and eliminates the portion of the stomach that produces the hunger stimulation hormone ( Ghrelin ).

It restricts the amount of food the stomach can hold, thus helping in weight loss.

The procedure is not reversible as 80% of the stomach is removed from the body.

The remaining stomach pouch can dilate on overeating in the longer run.
