Sleeve gastrectomy is a relatively new bariatric operation, and currently comprises 10-20 percent of bariatric operations performed in the US: This number is expected to rise in coming years.

Sleeve gastrectomy involves removal of the majority of the stomach, leaving a narrow “sleeve” of stomach that limits food intake much like a gastric pouch, but without the need to rearrange intestinal anatomy. Sleeve gastrectomy thus restricts the amount of food a person can eat and provides a feeling of fullness.
Weight loss after sleeve gastrectomy ranges from 50-60 percent of excess weight in most patients, similar to gastric bypass. More than 80 percent of patients will experience marked improvement in related diseases such as diabetes, sleep apnea, high blood pressure, fatty liver disease, osteoarthritis, and other diseases
