Vertical sleeve gastrectomy (VSG) is surgery to decrease the structure and size of your stomach. This restricts the amount of food you are able to consume.
This surgery involves re-shaping the stomach to reduce the amount of food it can hold.

What to Expect
Each bariatric surgery program has specific requirements. Your program will likely include the following:
- Physical exam and review of medical history
- Blood test and other tests
- Meetings with a registered dietitian
- Mental health test and counseling
Leading up to your procedure:
- Talk to your doctor about your medications, herbs, and dietary supplements. You may be asked to stop taking some medications up to one week before the procedure.
- Do not start any new medications, herbs, or supplements without talking to your doctor.
- Arrange for a ride to and from the hospital.
- Arrange for help at home as you recover.
- You may be given antibiotics.
- You may be given laxatives and/or an enema to clear your intestines.
- The night before, eat a light meal. Do not eat or drink anything after midnight unless told otherwise by your doctor.

will be given through an IV. It will block pain and keep you asleep through surgery.
Several small cuts will be made in your abdomen. Gas will be pumped in to inflate your abdomen, making it easier for the doctor to see. A laparoscope and surgical tools will be inserted through the incisions. A laparoscope is a thin, lighted tool with a tiny camera. It sends images of your abdominal cavity to a monitor. Your doctor will operate while viewing the monitor.
Surgical staples will be used to divide the stomach vertically. The new stomach will be the shape of a slim banana. The rest of the stomach will be removed. Your new stomach can hold 50-150 mL (milliliters) of food—about 10% of what a normal adult stomach can hold. Incisions will be closed with staples or stitches.
In some cases, the doctor may need to switch to open surgery.
The breathing tube and catheter will be removed.
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
The usual length of stay is 2-3 days.
You can expect the following:
- A small tube with a camera may be used to look down your throat and into your stomach to check for problems.
- You will receive nutrition through an IV, but then slowly start eating again.
In the hospital, you may be asked to:
- Use a device called an incentive spirometer to prevent breathing problems
- Wear elastic surgical stockings or boots to promote blood flow in your legs
- Get up and walk daily
Your bowels will work more slowly than usual. Chewing gum may help speed the process of your bowel function returning to normal.
During your stay, the hospital staff will take steps to reduce your chance of infection such as:
- Washing their hands
- Wearing gloves or masks
- Keeping your incisions covered
There are also steps you can take to reduce your chance of infection such as:
- Washing your hands often and reminding visitors and healthcare providers to do the same
