Bariatric, metabolic and endoscopic treatments.
Rather than selling one operation, we separate 16 current and historical procedures by clinical status and compare appropriate options with Dr Kenan Afilitak and the bariatric team.

Assess my suitabilityA first screening step
Calculate BMI—then compare options with the team.
BMI is a starting point, not a procedure selector. Medical history, reflux, metabolic health and capacity for follow-up also matter.
Your result—
Enter your height and weight for a screening BMI estimate.
BMI is a screening measure, not a diagnosis or a decision about surgery. Medical history, related conditions, nutrition, previous weight-management attempts and surgeon assessment are also required.
Frequently asked questions
Clear answers before choosing treatment.
What to know about suitability, price, clinician and aftercare before the first consultation.
01Which bariatric procedure is right for me?+
Procedure choice is not based on BMI alone. Reflux, diabetes, previous surgery, medicines, nutrition, goals and capacity for long-term follow-up are reviewed with the surgeon and bariatric team.
02How much is gastric sleeve surgery in Istanbul?+
IOC’s published package price is £1,800 for clinically accepted primary gastric sleeve cases. Final scope is confirmed in writing after medical assessment.
03Why are fixed prices not shown for every treatment?+
Hospital time, tests, devices or materials and follow-up can vary for bypass, advanced metabolic and endoscopic procedures. An itemised quote follows assessment.
04Does Dr Kenan Afilitak plan the treatment?+
Bariatric and metabolic surgical assessments are planned with Dr Kenan Afilitak and the relevant multidisciplinary team. The responsible clinician, hospital and follow-up plan are confirmed in writing before booking.
05How does aftercare work?+
Nutrition stages, vitamin and medicine guidance, blood-test timing, urgent warning signs and coordination contacts are defined in the written aftercare plan for the chosen procedure.
