Sleeve Gastrectomy

Sleeve gastrectomy is one of the food intake-restricting operations commonly applied in obesity surgery.

Patients who have had sleeve gastrectomy do not have a problem in absorbtion of nutrients, therefore no routine vitamin and mineral support is required.


Although it is generally a sufficient operation for many cases, for patients with SUPEROBESITY, this is performed as a preparative intervention prior to malabsorbtive surgery to reduce possibility of complications.

It is an important alternative offered to patients whose body mass index is over 40.


During this operation, the bigger side of the stomach is vertically cut and taken out and a new stomach with a volume of 150-200 cc is formed.

The decrease in stomach volume leads to restriction of food intake whereas the feeling of fullness due to the removal of the fundus section of stomach (that secretes ghrelin hormone known as ‘hormone of hunger’) supports the weight loss by decreasing the appetite.


The potential complications of the operation are bleeding, organ injury, emboli and complications due to anaesthesia that count for all surgical operations.

The only complication specific to the operation is the pain due to cut and sutured line of the stomach. During the operation, the stomach is swelled with special-blue coloured serum by which the sutured line is controlled and impermeability is tested. In this way, the risk is brought to minimum.

Sometimes, a second operation or interventions other than operations may be required.

Risk of death due to operation is very low (0.2%).


After sleeve gastrectomy, 60-70% of the excess weight is lost within the first 1-2 years. In many studies, the results have been found close to Gastric Bypass.

As it is a method only restricting food intake, the effect may decrease in individuals having a diet of high calory food and beverages.

In the long-term, the rate for putting on weight is 10-20% and the rate for being morbid obese is 2%. In such cases, the procedures like gastric bypass or duodenal switch may be preferred.

What is Lifelong Obesity Control?

There have been so many research on controlling obesity for years. Currently, number of studies on keeping the acquired weight is much higher than loosing weight.

The most important issue is keeping the weight off.

It has been found out that physical activity is necessary not only for loosing weight, but for also keeping the weight off.

Aiming weight loss only is never sufficient in obesity treatment. Besides loosing weight, improving health and reducing health risks are quite important as well. We have to focus on managing our weight. Aiming a weight loss determined according to the level and type of obesity, and considering the age and living of the individual is much better than acquiring an almost impossible target by means of unhealthy practices.

Loosing weight at an intermediate level and keeping the weight stable is a much more successful approach than loosing too much weight in a while and regain all that given weight.


A preparative interview is carried with obesity surgeon. After examination, the route to follow is programmed.

Comprehensive blood tests are taken prior to operation. The patient is examined by a dietician, cardiologist, pulmonologist, internist, anaesthesist and a general surgery specialist.

Gastroscopy operation is performed by a surgeon.

The treatment is determined according to evaluation of results and the surgery is followed through by obesity surgeon.

Patient stays at hospital for the 3-4 days following the laparoscopic operation that takes 1-1.5 hours.

Patient can be discharged from hospital at the 4th day of operation and go back to social life but starting exercises and heavy duty has to be postponed until 1-2 weeks from then on.

The diet of the patient has to be reviewed and arrangements should be made accordingly with regular controls.
