Depending o the type of the operation, some changes are made on stomach or intestines. It is wholly closed (laparascopic). It is conducted in the stomach through the 0.5 – 1.5mm wide holes through the body. On average, it takes 30 – 90 minutes. After the operation, very little pain is felt and the patent can stand up after 3 hours. In a few days the patient can leave hospital and be back at their desk. Since the incisions are very small, aesthetic results are successful.


It is the most common obesity operation. Sleeve gastrectomy lasts 30-90 minutes and it is conducted as a closed operation. In the operation, 80% of the stomach is cut and taken out with a single use device called a stapler. Since the stomach looks like a thin and long tube, it is also called tube stomach surgery. As the stomach volume decreases significantly, the patient feels full with little food.

On the upper die of the stomach, called fundus, the hunger hormone Ghrelin is synthesised and sent to the brain. As fundus is compeltely removed in this operation, the level of hunger hormone in the body will decline significantly. Thus, the patient does not get hungry, which helps the patients to develop their self control and comply with their new dietary schedule.

The patients receive vitamins in the 6 months after the operation. The post operation controls are finalised in a short while. The patient does not need the vitamins forever.

A second operation may be necessary for few patients. Another advantage of sleeve gastrectomy is that the second operation can be applied much more easily.


A surgical treatment can be conducted on type 2 diabetes patients who cannot regulate their blood sugar with standard treatments and develop organ damage due to high blood sugar and who has enough insulin reserves. In diabetes treatment, first the stomach volume is shrank to reduce food intake. A new path from the intestines to the stomach is formed and therefore food absorbtion is therefore decreased. Thanks to GLP and GIP, insulin release facilitators, blood sugar control is easily obtained.

The operation takes 2 hours in average. It is conducted closed (laparoscopically). The patient can stand up the same day, can get out of the hospital in 4-7 days and can return at their desk in a week. As the blood sugar level of the patient will be more and more regulated, their need for insulin and other diabetic medicine will be gradually declined. Due to regular checks, the dosage of medicines will be decreased and in many cases the patient will not even need the medicine


Every treatment and every operation has its own risk. Obesity operations, when done by a team of experts in good conditions, are very secure. We are taking every precaution possible to reduce risks, evaluate the patients carefully before the operation and use modern equipment of highest quality. Complication ratios are not higher than other closed stomach/gallbladder operations. Tests are conducted for bleeding before the end of the operation and necessary treatment is done. To prevent embolism, special devices are used and operation duration is kept at a minimum.

The real risk is to try continue life with obesity. As the scientific research shows, the risk in an obesity operation is much lower than living with obesity. Obese patients are known to live 15 years less than patients with normal weights.
