Gastric Sleeve in Istanbul: overview
In a gastric sleeve, around 75–80 per cent of the stomach is removed by keyhole (laparoscopic) surgery, leaving a tube-shaped stomach. Stomach volume is reduced and most of the part that produces the hunger hormone is removed. It is generally considered for a body mass index of 40 or above, or 35 or above with an accompanying condition; the procedure is irreversible.

Who is it for?
A gastric sleeve suits adults who meet the criteria for bariatric surgery and do not have significant reflux, since a sleeve can worsen reflux in some people. It is often chosen by patients who prefer not to have their intestines rerouted.
How the sleeve works
About three quarters of the stomach is removed laparoscopically, leaving a narrow tube. The smaller stomach fills quickly, and the reduction of the hunger hormone ghrelin, produced mainly in the removed part, reduces appetite. The operation takes around one to one and a half hours.
Eating after a sleeve
The diet progresses in stages: clear liquids, then full liquids, purées, soft food and finally normal textures, usually over four to six weeks. Protein comes first at every meal, drinks are taken between meals rather than with them, and vitamin supplements are recommended.
Travelling from Europe for a sleeve
Plan about 5 to 7 days in Istanbul, with two or three nights in hospital. Walk on the flight home and drink small sips of water regularly. Before you travel, tell your GP; afterwards, dietitian guidance and follow-up continue remotely, and your reports are provided in English.

How long does Gastric Sleeve take?
The procedure takes about 1–1.5 hours. Anaesthesia: general anaesthesia.
How long do I stay in hospital and in Turkey?
Hospital stay: 2–3 nights. The total stay in Türkiye is usually planned at 5–7 days; your physician confirms the exact length at your check-up.
Is Gastric Sleeve in Turkey safe? What are the risks?
Every medical procedure carries risk: infection, bleeding, anaesthesia-related problems and healing that differs from what was expected are the main ones. To reduce risk, the procedure is performed by a specialist at a licensed hospital after pre-operative tests. Your physician explains the risks specific to you at your examination.
When can I go back to work and exercise?
Desk work is usually possible within 14 days and sport after 6 weeks. These times vary from person to person.
Will there be scars?
A few small incisions in the abdomen (keyhole). Scars are noticeable in the first months and fade with time; how they heal depends on your skin.
When will I see the result?
The first change is visible as swelling settles; the final result appears in about 18 months. Results vary from person to person and cannot be guaranteed.
Can I see before and after photos?
Out of respect for patient privacy and under healthcare regulations, patient photos are shared only with the patient's consent. In your consultation the physician explains what is realistic in your case.
How do I choose the best clinic for Gastric Sleeve in Istanbul?
There is no single “best clinic” for everyone; for a safe choice, check these: a Health Tourism Authorisation Certificate, the name of the hospital and the operating surgeon, a written plan based on a physician's assessment, an itemised quote and aftercare. New City Clinic is an authorised intermediary registered with the Turkish Ministry of Health and HealthTürkiye; it publishes its authorisation, TÜRSAB and ISO certificates on this site and gives you all of this in writing with your quote.
Can a sleeve be reversed?
No. Part of the stomach is removed permanently, which is why the decision is made carefully.
Can I get pregnant after a sleeve?
Yes, but it is usually advised to wait 12 to 18 months until the weight has stabilised.
Is Gastric Sleeve in Turkey safe?
Like any operation, Gastric Sleeve carries risks, and the risk depends far more on where and by whom it is done than on the country. The serious cases reported in the press have mostly involved unlicensed premises, non-specialists or too many procedures in one session. A safe choice means a hospital licensed by the Turkish Ministry of Health, a named specialist surgeon, an anaesthetist, pre-operative tests and a long enough stay. New City Clinic is an authorised intermediary registered with the Ministry of Health and HealthTürkiye, and you receive the hospital and surgeon details in writing before you travel.
Why is Gastric Sleeve cheaper in Turkey than in the UK?
The difference comes mainly from lower operating and staff costs and the exchange rate; implants, materials and techniques follow the same international standards. Even so, do not choose on price alone: check the hospital licence, the surgeon’s specialty and exactly what the package includes.
