what is a sleeve surgery

A sleeve surgery, also known as a sleeve gastrectomy or gastric sleeve surgery, is a surgical weight-loss procedure that removes a large portion of the stomach, leaving behind a tubular "sleeve" about the size and shape of a banana. The surgery works by reducing the size of the stomach, which means that a person will feel full more quickly and eat less, leading to weight loss. The procedure is typically performed laparoscopically, which involves making small incisions in the abdomen. Sleeve surgery is used to treat severe obesity and is advised for people who have tried other weight loss methods without long-term success. It is typically done in the hospital, and the specifics of the surgery depend on the individual situation and the hospitals or doctor's practices. The surgery can improve and sometimes eliminate diseases related to obesity, such as insulin resistance, type 2 diabetes, hypertension, and hyperlipidemia.
