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% of the stomach is removed, leaving a tube-shaped stomach about the size and shape of a banana.
Sleeve gastrectomy is done to help you lose excess weight and reduce your risk of potentially life-threatening weight-related health problems, including:

Sleeve gastrectomy is done in the hospital. Depending on your recovery, your hospital stay may last one to two nights.
The specifics of your surgery depend on your individual situation and the hospital's or doctor's practices. Some sleeve gastrectomies are done with traditional large (open) incisions in the abdomen. But sleeve gastrectomy is typically performed laparoscopically, which involves inserting small instruments through multiple small incisions in the upper abdomen.
You are given general anesthesia before your surgery begins. Anesthesia is medicine that keeps you asleep and comfortable during surgery.
To perform a sleeve gastrectomy, the surgeon creates a narrow sleeve by stapling the stomach vertically and removing the larger, curved part of the stomach.
Surgery usually takes one to two hours. After surgery, you awaken in a recovery room, where medical staff monitors you for any complications.
After sleeve gastrectomy, your diet begins with sugar-free, noncarbonated liquids for the first seven days, then progresses to pureed foods for three weeks, and finally to regular foods approximately four weeks after your surgery. You will be required to take a multivitamin twice a day, a calcium supplement once a day, and a vitamin B-12 injection once a month for life.
You'll have frequent medical checkups to monitor your health in the first several months after weight-loss surgery. You may need laboratory testing, bloodwork and various exams.
You may experience changes as your body reacts to the rapid weight loss in the first three to six months after sleeve gastrectomy, including:
