Short answer: Gastric sleeve (sleeve gastrectomy) in Istanbul is performed in Ministry-licensed, JCI-accredited hospitals by experienced bariatric surgeons. With Buşra Nur Özger (BNÖ Health) the whole journey is planned for you: pre-assessment, surgeon and hospital, VIP transfers, hotel, a personal patient assistant and follow-up after you fly home. Most international patients stay 6–7 days.
Who is a candidate for gastric sleeve surgery?
Gastric sleeve is usually considered for adults with a BMI of 40 or above, or 35 and above with an obesity-related condition such as type 2 diabetes, sleep apnoea or high blood pressure, when diet and exercise have not produced lasting results. The final decision is made by the bariatric surgeon after reviewing your medical history, blood tests and, if needed, an endoscopy.
How the procedure works
The surgeon removes roughly 75–80% of the stomach laparoscopically (keyhole surgery), leaving a narrow “sleeve”. The smaller stomach limits portion size and reduces ghrelin, the hunger hormone. The operation itself takes about 1–2 hours under general anaesthesia and most patients stay in hospital for 2–3 nights.

How much does gastric sleeve cost in Turkey?
All-inclusive gastric sleeve packages in Istanbul are generally far lower than UK, Irish, US or German private prices because of lower operating costs and the exchange rate, not because of lower standards. Packages typically cover surgeon and hospital fees, pre-operative tests, 2–3 nights in hospital, hotel, VIP transfers, a patient assistant and follow-up. The exact figure depends on your BMI, medical needs and hotel choice, so we provide a written quote after your assessment.
Recovery and results
Most people return to desk work within 1–2 weeks and to full activity within 4–6 weeks. Typical weight loss is 60–70% of excess weight within 12–18 months when the dietary and follow-up plan is followed. Results vary from person to person.
Frequently asked questions
How long do I need to stay in Istanbul for gastric sleeve surgery?
Usually 6–7 days: 2–3 nights in hospital and the rest at the hotel for check-ups before your fit-to-fly assessment.
Is gastric sleeve surgery in Turkey safe?
Safety depends on the hospital and the surgeon, not the country. Buşra Nur Özger works only with Ministry-licensed, JCI-accredited hospitals and experienced bariatric teams, and coordinates assessment, surgery and aftercare end to end.
What BMI do I need for a gastric sleeve?
Generally a BMI of 40+, or 35+ with an obesity-related illness. Eligibility is confirmed by the surgeon after reviewing your medical history.
Can I combine gastric sleeve with a tummy tuck?
Not at the same time. Body contouring such as a tummy tuck is planned 12–18 months later, once your weight has stabilised. Many of our patients return to Istanbul for post-bariatric surgery.
Do you provide aftercare once I am back home?
Yes. You receive a dietary plan and vitamin protocol, and our team schedules online check-ins; you can reach us on WhatsApp 24/7.
