IOC Editorial & Medical Information TeamPrepared with more than 22 years of bariatric-centre experience and checked against the official sources listed below. See our review process.
Instructions from your own surgical or prescribing team take priority over this general guide. Contact local emergency care for severe or rapidly worsening symptoms.
Key takeaways
- No regulator or medical society publishes a universal ranking of the best gastric sleeve surgeon or hospital in Turkey.
- Compare a named surgeon and a named hospital—not a sales brand—using training, sleeve-specific experience, complication systems and written aftercare.
- A responsible provider should assess suitability before payment pressure, explain alternatives and risks, and document what happens if recovery does not follow the expected plan.
Is there a best gastric sleeve surgeon in Turkey?
There is no responsible universal league table that identifies one surgeon or hospital as 'the best' for every patient. Your safest choice depends on your health, previous operations, medicines, anaesthetic risk, the procedure being considered and whether the provider can support you before and long after surgery.
Treat 'best' as a comparison question, not an award claim. Ask for the legal name of the treating hospital, the surgeon expected to operate, the multidisciplinary team, the written package and the complication pathway before you pay or book flights.
1–3: Verify the named surgeon
NICE says a bariatric surgeon should have relevant supervised training and specialist bariatric experience. A website biography is a starting point, not independent verification. Request the surgeon's full name, specialty, professional registration information and the hospital where the operation is planned.
- 1. Confirm the full name and specialty of the surgeon expected to operate.
- 2. Ask how much of the surgeon's current work is bariatric and specifically primary sleeve gastrectomy.
- 3. Confirm who covers the ward, nights and weekends if the lead surgeon is unavailable.
4–6: Check the hospital and emergency systems
A skilled surgeon still needs a functioning hospital system. Confirm anaesthetic assessment, operating-theatre standards, imaging, endoscopy, blood products, high-dependency or intensive-care escalation and the route for treating a suspected leak, bleeding or clot.
Ask whether a complication would be managed in the same hospital, transferred elsewhere or charged separately. The answer should name the responsible team and explain how decisions are made outside office hours.
- 4. Obtain the hospital's legal name and full address before travel.
- 5. Ask what diagnostic and emergency services are available on site at all times.
- 6. Request the written transfer, reoperation and extended-stay pathway.
7–9: Ask for outcomes with a denominator
A percentage is meaningful only when you know what it measures. Ask for a defined period, the number of primary sleeves included, whether revision and emergency cases were separated, and how leaks, bleeding, readmission, reoperation, transfer and death were counted.
Before-and-after photographs and reviews describe individual experiences; they do not replace audited clinical outcomes. A provider should not guarantee a weight-loss result or imply that one photograph predicts yours.
- 7. Ask for recent primary-sleeve case numbers and the dates covered.
- 8. Ask how complications and readmissions are defined and followed after patients fly home.
- 9. Distinguish verified patient stories from audited clinical outcome data.
10–12: Evaluate assessment and aftercare
NICE describes bariatric care as multidisciplinary and includes medical, nutritional, psychological and surgical assessment. A quick BMI check alone cannot establish that surgery is appropriate. Your complete medical, medicine and previous-surgery history needs review before a final plan is accepted.
Aftercare should identify who answers routine questions, who reviews warning symptoms, how nutrition progresses, which blood tests are expected and how longer-term annual monitoring will be arranged in your home country.
- 10. Confirm medical, anaesthetic, nutrition and psychological assessment routes.
- 11. Obtain the staged diet, medicine, supplement and urgent-contact plan in writing.
- 12. Ask how records will be transferred to your GP or local bariatric team.
13–15: Compare the complete written offer
The lowest headline price is not automatically the lowest total cost. Compare the operation, hospital nights, hotel, transfers, tests, medicines, interpreter, aftercare, cancellation terms and exclusions. Flights, specialist insurance and unexpected care may sit outside the package.
- 13. Match every price to an itemised inclusion and exclusion list.
- 14. Confirm who pays if surgery is postponed, the stay is extended or extra care is needed.
- 15. Walk away from guaranteed outcomes, unnamed clinicians, missing risk discussion or pressure to pay immediately.
How to assess Dr Kenan Afilitak and IOC
Apply the same checklist to Istanbul Obesity Center. The planned lead surgeon is Dr Kenan Afilitak; the published team includes Bariatric Clinical Coordinator Mustafa Hekin and Bariatric Dietitian Aylin Demir. Review their named profiles, ask who will personally provide each part of your care and confirm the treating hospital and final scope in writing.
IOC publishes a £1,800 package for eligible uncomplicated primary cases, one year of remote dietitian follow-up and access to a 300+ patient support group. These are useful comparison points, but they do not replace individual suitability assessment, informed consent, suitable insurance or lifelong health monitoring.

Open treatment pageFrequently asked questions
Who is the best doctor for gastric sleeve in Turkey?
There is no reliable universal ranking. Compare the named surgeon's training and current sleeve experience, the named hospital, recent defined outcomes, complication systems and long-term aftercare for your individual needs.
What should I ask a gastric sleeve surgeon before booking?
Ask about suitability, alternatives, case volume, defined outcomes, anaesthetic and complication cover, the hospital, expected stay, fit-to-fly decision, aftercare and every package exclusion.
Is a five-star rating enough to choose a clinic?
No. Read recent positive, neutral and critical reviews on independent source platforms, then verify the surgeon, hospital, outcome definitions and aftercare separately.
Should the surgeon be named before I pay?
Yes. The planned treating surgeon and hospital should be named and confirmed in writing, while recognising that genuine clinical or operational reasons can occasionally require a documented change.
Does a low price mean the surgery is unsafe?
Price alone does not establish safety. Compare the complete clinical and logistical scope, exclusions, complication pathway and the people and hospital responsible for care.
