Laparoscopic Sleeve Gastrectomy


A laparoscopic sleeve gastrectomy (LSG) is surgery to remove part of the stomach so the remaining stomach forms a small tube. Once the stomach is made smaller, you will feel full faster and have a decreased desire for food. LSG is commonly done as a first surgery before a more involved weight-loss surgery can be done.



  • Medicines may be given to decrease pain or stomach acid production. Ask your primary healthcare provider (PHP) how to take prescription pain medicine safely.
  • Take your medicine as directed. Contact your PHP if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your PHP or surgeon as directed:

You may need to return for blood tests. Write down your questions so you remember to ask them during your visits.


You will need to eat foods low in calories and fat and high in protein. Foods high in protein are meat, poultry (chicken and turkey), fish, eggs, nuts, and legumes (peas and beans). Avoid chewy meats because they may be harder for your stomach to digest. Dairy products, such as milk and yogurt, are also good sources of protein. If you are on a pureed diet, you may need to puree your food in a blender or food processor. Eat slowly, and chew your food well before you swallow.

Take a multivitamin:

Take a daily multivitamin as ordered by your PHP. Ask your PHP which multivitamin is best for you.


Daily exercise can help you burn extra calories and lose weight. Exercise makes the heart stronger, lowers blood pressure, and helps keep you healthy. It is best to start exercising slowly and do more as you get stronger. Do not start an exercise program until you talk with your PHP. Together you can plan the best exercise program for you.

Wound care:

Carefully wash the wound with soap and water. Dry the area and put on new, clean bandages as directed. Change your bandages when they get wet or dirty.

Contact your PHP or surgeon if:

  • You have nausea or vomiting.
  • You have new or increased heartburn.
  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • You feel lightheaded, short of breath, and have chest pain.
  • You cough up blood.
  • Your arm or leg feels warm, tender, and painful. It may look swollen and red.
  • You have new or increased abdominal pain.
  • You have a fever and chills.
  • Your wounds are draining pus or look red or swollen. They may feel warm, painful, or tender.
