What is Gastric Sleeve Surgery?

Gastric sleeve surgery, also called a vertical sleeve gastrectomy, is a surgical weight-loss procedure. This procedure is typically performed laparoscopically, which involves inserting small instruments through multiple small incisions in the upper abdomen. During sleeve gastrectomy, approximately 80% of the stomach is removed. Gastric Sleeve surgery helps to patient lose weight in two ways:

1.Hormonal way: Ghrelin is a hormone that sends signals from stomach to brain and induces a feel of hunger. Since the part that produces ghrelin hormone is removed from the stomach, urge to eat is greatly reduced.

2.Restrictive way: As the stomach volume shrinks, less food and calories will be taken, so weight loss occurs. The patient’s stomach is significantly smaller after the operation so they will feel satiated sooner.

How Gastric Sleeve Surgery is performed ?

Gastric Sleeve surgery is performed under general anesthesia and it is done laparoscopically which is a closed method. During the procedure, the abdominal wall is not cut out, the operation is performed with special surgical instruments with a camera attached on the tip. In this way, recovery after surgery is faster. In laparoscopical surgeries muscle tissue is not cut or damaged, therefore patient does not experience much pain after the surgery and pain is minimized by giving painkillers to the patient after the surgery. The surgery usually takes 2 hours. After the operation, the patient rests in the recovery room and the health status is monitored by surgeon and nurses.

Recovery from Gastric Sleeve Surgery

Following your operation, you will stay in hospital for for 3 nights. Your stomach might be swollen and sore for several days and your surgeon may prescribe painkiller medication. You will be able to drink clear liquids the day after surgery. At the end of 3 days, you will go through routine tests again and if the doctor approves, you will be discharged. After being discharged from the hospital, you and your companion will stay in a hotel with all the comfort in the central location for 3-4 days and your health will be monitored under the supervision of a surgeon. If there are no complications, you can return to your country and your daily life. Our dietician will prepare a special diet program for you and explain in detail what should be eaten and what should not be eaten during the postoperative period. Walk as much as you can in the first month. This helps the healing process and promotes weight loss. If you are working at desk job, you can return to work after 1 week. However, if you are in a physically heavy job, we recommend that you return to work after 3 weeks.

How much weight can be lost with Gastric Sleeve ?

Gastric sleeve surgery patients will lose 60% of their excess weight in approximately one and a half years. Rapid weight loss may occur within the first three months after surgery. The reason for this is that the patient is fed with liquid and puree after surgery. Although the weight loss rate of the patient slows down after three months, the weight loss process will continue for up to two years.

It is very important that patients follow the surgeon’s and dietician’s instructions after surgery. We recommend exercising along with the diet plan. Only walking can be done in the first month after surgery. In the following months, swimming and doing non-heavy sports support weight loss and prevent sagging.

Our Patient Reviews

Gastric Sleeve
All around very professional staff and doctor. They walked me through every step regarding the treatment and what I had to do afterwards. I immediately lost my appetite on operation day and I am not even craving sweets or fast food since. I got advised on my diet by a professional dietitian and the diet is easy to follow. It has been only 2 weeks and I have dropped 10 pounds since the operation. Do not ever hesitate to get this operation done, I feel like I am born again !
Gastric Sleeve
I had the operation done at about a week ago at September. I got recommended gastric sleeve by a friend who got it done at segmed and doctor banli. His surgery was done 2 years ago and his health and weight is currently ideal. I was worried about covid but they take adequate precautions and it made me feel a lot better because this was the first time I ever had a surgery. So far I am feeling great, I am in touch with the dietitian and the psychologist. I wish I had it done sooner.
Gastric Bypass
In general I am really scared of doctors and operations but after talking to segmed staff and the doctor on whatsapp I've overcome my fear. They were very assuring and comforting thanks to their knowledge and sincerity. Even after a year I am still in touch with them. I dropped from 136 to 82 kg(21.4 stones to 13 stones) since the operation. Thanks guys !
Gastric Sleeve
About 2 years ago I had enough with diabetes and all the medication that come with it. I looked up a ton of clinics in turkey and decided to get it done after talking to other diabetic patients. The staff at the clinic were helpful and professional and the hotel was comfortable. The worst part is I could not eat enough Turkish food due to surgery ! The doctor and the staff were very confident with their success with diabetic patients and thankfully it worked for me as well. I don't have to deal it anymore.
