Laparoscopic sleeve gastrectomy is a permanent weight loss surgery that has grown in popularity over the last few years. Patients lose, on average, about 60 percent of their excess weight.
Laparoscopic sleeve gastrectomy, often just called sleeve surgery, removes about 80 percent of the stomach. Your surgeon creates a thin, vertical stomach pouch that is roughly the size of a banana.
Similar to other weight loss surgeries, sleeve surgery reduces the amount of food that your stomach can hold. The surgery may also impact hormones in the gut that trigger hunger, fullness and blood sugar control.
After surgery, your body still digests food naturally. Food passes through the entire digestive track and absorbs into the body.
