Gastric Sleeve Surgery is one of the methods used to treat obesity. In this procedure, around 80% of the stomach is removed and the remaining part is closed with a staple suture. This ensures that patients achieve a feeling of fullness with less food and consume fewer calories.

HOW IS Gastric Sleeve Surgery PERFORMED?

The Gastric Sleeve Surgery procedure developed for obesity is a surgical procedure. In this procedure, the normal surgical procedure steps are followed. In addition, the laparoscopic method, i.e. closed surgery, is preferred if the patient’s condition is suitable.

Thanks to closed surgery, the process will be much easier and smoother. In particular, most of the risks and side effects of open surgery are eliminated. All this means a more comfortable healing process and faster weight loss. The steps involved in a Gastric Sleeve Surgery are as follows:

  • Initially, patients are put under general anesthesia.
  • Incisions, no larger than 1 cm, are made at 4-5 points in the abdominal region.
  • A camera is inserted through one of these incisions into the abdominal cavity, while medical instruments are inserted through the other incisions.
  • The camera’s images are displayed on the screen, and the operation is carried out.
  • First, a calibration tube is inserted into the stomach to shape it.
  • The remaining part is cut out and removed from the body.
  • The new stomach is closed with a stapling device, and leakage checks are performed in this area (staple line).
  • The procedure is completed after checking the tightness of the puncture.

After the procedure, patients remain in hospital for 2-4 days. During this time, leakage checks are continued. The main symptoms of leakage in the affected area are high fever and new onset of abdominal pain. If these symptoms occur, a leak is suspected and the necessary checks are carried out.

The tube used in the gastric sleeve is very important. The reason why this tube is called a calibration tube is that it calibrates the part of the stomach that will remain. If this tube is too narrow, it can cause blockages and narrowing. Therefore, it is very important to choose the right tube.

WHO CAN UNDERGO A Gastric Sleeve Surgery?

Gastric Sleeve Surgery is a treatment for obesity. It should be known that this procedure is not a weight loss surgery. Therefore, it is only suitable for obesity patients, it is not suitable for other healthy people.

Whether a person is obese or not is determined by their body mass index. People with a body mass index of 30 or more are considered obese. Gastric Sleeve Surgery is performed on patients with a body mass index of 35 or more. People with a BMI between 30 and 35 can only undergo the operation if they have high blood pressure and type 2 diabetes.

In addition to the body mass index, patients must also be suitable for anesthesia and surgery. Otherwise, the procedure will not be performed. The following candidates are not suitable for the procedure:

  • People with heart failure
  • Individuals with liver diseases
  • Persons with health issues preventing anesthesia
  • Individuals with mental disorders
  • Drug and alcohol addicts

Recovery after a Gastric Sleeve Surgery

The recovery process after a Gastric Sleeve Surgery varies from patient to patient. However, the general features of this process are similar in almost all patients. Patients coming out of surgery are monitored in hospital for 2-4 days. Here they are only fed with clear liquids.

It is normal to experience pain and swelling in the operation area during the first few days. Patients are given painkillers to relieve the pain. After some time, the pain and swelling will subside and disappear. No additional treatment is required during this process.

Discharged patients should rest at home for the first few days and continue their liquid diet. Nutrition is very important in this process. The prepared diet program should be implemented without the slightest flexibility.

After the first 2 weeks, the healing process is largely complete. After that, patients can go about their daily lives again, provided they do not lift heavy loads, are not overtired, do not strain themselves and do not work in heavy jobs. It takes an average of 4-6 weeks until healing is complete.


After the procedure, patients quickly begin to lose weight. Those who follow a diet and exercise lose an average of 8-10 kg in the first month. After that, the weight loss decreases but averages 6-7 kg. Therefore, patients lose most of their excess weight in the first 6 months.

Gastric Sleeve Surgery facilitates weight loss. However, patients should avoid high-calorie foods and overeating. Otherwise, the desired results will not be fully achieved.
