Obesity is characterized with highest increase in prevalence around the world. Even though there are tens of medical etiologies of obesity, the most important ones are abnormal weight gain and sedentary lifestyle. Life time of obese patients is approximately 15 years shorter than other people. Furthermore obesity is a risk factor for cancers such as colorectal cancers, breast cancer and prostate cancer.

Sleeve gastrectomy is one of the most common surgical weight loss methods.


In gastric sleeve surgery, approximately 70 to 80 % of the stomach is surgically removed and the stomach is given a tube shape.So this is a volume restriction method.You will feel full sooner,  due to the as the lesser volume of the stomach .

 ‘Ghrelin’ hormone souce is totally excised and this helps diminishing appetite and losing weight.

Why Gastric Sleeve Surgery

This is one of the most common methods used for obesity surgery in our hospital more than 1000, since it is easy to practice and leads to less complications although it is as effective as other complicated surgical methods. In this method, 80 to 90% of stomach is removed and transformed into a form of tube. This surgery takes about one to two hours and is performed with closed (laparoscopic) method. Hospital stay is two to three days. Patients can start consuming normal foods after they eat liquid foods for two weeks and soft foods for the subsequent two weeks after the surgery..


As the case for all surgeries, gastric sleeve surgery involves several risks.


  • Bleeding
  • Infection
  • Thrombosis (blood clot)
  • Leakage from anostomosis line
  • Damage to other organs
  • Transition to open surgery
  • Anesthesia-related complications

Your surgeon will explain in detail whether those risks apply to you or if so, the rate of occurrence.


The first phase of preoperative preparation is same in all Medicana Hospitals. Decision of gastric sleeve surgery is made following a series of medical tests and examinations.  Your doctor will make a comprehensive assessment to determine whether this surgery helps your complaints or not.

In the preoperative period, all of your prescription and over-the-counter medications, your comorbidities such as obesity-induced hypertension, diabetes mellitus and cardiovascular diseases, and your overall health will be assessed.  All these assessments will both help you be ready for the surgery and minimize the problems that can be encountered during or after the surgery.

  • Review of health history
  • A detailed physical examination
  • Necessary laboratory tests and radiology studies
  • Assessment by anesthesiologist and other laboratory tests and radiology studies to minimize anesthesia-related complications

After it is verified that the surgery does not pose risk, you will be asked to quit smoking, if you are a smoker, and to stop taking certain medications that increase risk of bleeding. All other prescribed and over-the-counter medications, herbal products and supplements will also be questioned and you will be informed to continue or stop taking them.

A preoperative discussion with your surgeon about gastric sleeve surgery is very important. All details of the procedure, potential risks and healing period are explained.  

Moreover, it is reasonable to plan discharge, post-discharge accommodation and travel at this phase in order to manage postoperative period better.

Surgery and early postoperative period

Gastric sleeve surgeries are performed under anesthesia with laparoscopic approach to a great extent.

However, open surgery can be performed subject to your surgeon’s decision, in case that your condition requires so or any problem is faced during the surgery.

Your surgeon makes small incisions.  First, your abdominal cavity is inflated by CO2 gas through one of those incisions. Then, a camera is inserted into your abdominal cavity. Other incisions are used for surgical instruments to be inserted into your abdominal cavity.

Next, after 75 to 80 % of your stomach is removed by your surgeon, your stomach is given a tube shape. Following all necessary controls in the surgery site, incisions are stitched and the procedure is ended.

After you recover from anesthesia and you are ready to walk, you will be mobilized by or under supervision of our healthcare professionals.

You will be given pain killer(s) after the surgery in order to manage the postoperative pain.

Treatments will be started and measures will be taken to eliminate risks arising out of clot formation.

You may also need to use antibiotics to prevent a possible infection.

It is very important that you follow all instructions of your doctor after the surgery to protect and support the outcome of the surgery.

You should see your surgeon for follow-up visits that are scheduled before you are discharged.

If you experience warmth and redness in your incision line, or if you have a fever or any symptoms that you think are due to surgery after you are discharged, contact your surgeon immediately.
