Long-term complications include vomiting and
Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications, such as:
You may have the following done:
- Physical exam and review of medical history
- Blood test and other tests to check your health
- Meetings with a registered dietitian
- Mental health test and counseling
Prior to the 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, like:
- Anti-inflammatory drugs

will be given through an IV. It will block pain and keep you asleep through the surgery.
An IV will be placed in your arm to give you fluids and medications. A breathing tube will be placed through your mouth and into your throat. This will help you breathe during surgery. You will also have a catheter placed in your bladder to drain urine.
An 8-10 inch incision will be made to open the abdomen. Surgical staples will 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.
Staples or stitches will be used to close the incision.
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 4-6 days. If there are any problems, you will need to stay longer.
- A small thin tube with a camera will be used to look down your throat and into your stomach to check for problems.
- You will receive nutrition through an IV at first, but slowly start eating again.
While 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
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
- Reminding your healthcare providers to wear gloves or masks
- Not allowing others to touch your incision
For a smooth recovery:
- Ask your doctor about when it is safe to shower, bathe, or soak in water.
- Do not drive or lift anything heavy for at least two weeks or until advised by your doctor.
- Walk every day.
- Your doctor may recommend that you meet with a therapist to discuss emotional changes after surgery.
- Follow your doctor’s instructions.
Return to normal activities in 2-3 weeks.
