Sleeve gastrectomy, also called a vertical sleeve gastrectomy, is a surgical weight-loss procedure. This procedure is typically performed laparoscopically, which involves inserting small instruments through multiple small incisions in the upper abdomen. During sleeve gastrectomy, about 80 percent of the stomach is removed, leaving a tube-shaped stomach about the size and shape of a banana.
Limiting the size of your stomach restricts the amount of food you are able to consume. In addition, the procedure prompts hormonal changes that assist with weight loss. The same hormonal changes also help relieve conditions associated with being overweight, such as high blood pressure or heart disease.
