Obesity surgery in Turkey: sleeve, bypass or revision
Gastric sleeve in Turkey
The most common procedure. Part of the stomach is removed, which reduces capacity and hunger hormones.
See gastric sleeve →Gastric bypass in Turkey
The stomach is made smaller and the intestine rerouted. Often considered for higher BMI or type 2 diabetes, and more involved than a sleeve.
See gastric bypass →Sleeve vs bypass: which one?
A side-by-side comparison of the two most common procedures.
Compare →Revision surgery
For patients whose earlier weight-loss surgery needs to be corrected or converted. The surgeon reviews your records first; the price depends on your case, so there is no fixed price.
See revision surgery →Bariatric surgery in Turkey: JCI-accredited ASV Yaşam Hospital
Sleeve and bypass are done laparoscopically: through several small incisions rather than one large cut. Surgery takes place at ASV Yaşam Hospital in Antalya, a JCI-accredited hospital. Your package includes 3 nights in the hospital. The surgeon decides when you are cleared to fly, typically around day 5–7 for most patients.

Weight loss surgery overseas: Antalya or Istanbul
Dr. Çaynak operates at ASV Yaşam Hospital in Antalya, on Turkey's Mediterranean coast, and he can also operate in Istanbul. Your coordinator confirms the city and hospital when you get your quote. Antalya is usually reached by connecting through Istanbul. Turkey is 7 hours ahead of New York in summer and 8 hours ahead in winter, so we schedule calls with that in mind.
ASV Yaşam Hospital: Gebizli Mah. 1116 Sk No:4, Muratpaşa/Antalya, Turkey (listed by the Antalya Provincial Health Directorate).
Recovery and preparation. Preparation starts weeks ahead: the surgeon's team tells you what to do before the operation, and what to expect after.

Bariatric surgery cost: Turkey quote vs US range
After the surgeon reviews your case, you receive one written, all-inclusive quote covering tests, surgery, hospital stay, hotel, medications, dietitian visits and airport transfers. Flights are not included. NIDDK, the US National Institutes of Health institute, says weight-loss surgery can cost $15,000 to $25,000 or more in the United States. Your exact price depends on the procedure and your case.
| Item | Gastric sleeve or bypass, Turkey (NexWell package) | Weight-loss surgery, United States (self-pay) |
|---|---|---|
| Price | Personal quote after your surgeon's assessment, flights not included. See the price list | $15,000–$25,000 USD or more |
| Source | Written quote from NexWell after the surgeon's review | NIDDK, “Definition & Facts of Weight-Loss Surgery” (page last reviewed Sept. 2020) |
Not an apples-to-apples comparison: the NIDDK range covers weight-loss surgery in general, not only sleeve gastrectomy, and varies by procedure and complications. Prices in US dollars; flights are not included in the Turkey package.
- Included: pre-operative tests, laparoscopic surgery, anesthesia, 3 nights in the hospital, hotel accommodation, dietitian consultations, first-month medications, compression stockings, airport transfers, 12-month remote follow-up.
- Not included: flights. The package price does not include your flights.
- Gastric bypass and sleeve are quoted after the same surgeon assessment.
- Revision surgery has no fixed price: it depends on your case and is quoted after the surgeon reviews your records.
Bariatric surgery abroad: 12 months of follow-up
- Remote check-ins with a dietitian for 12 months.
- Weight-loss surgery means lifelong changes: a new way of eating and vitamin supplements. Your dietitian and surgeon explain this before you decide.
- If you have severe pain, fever, vomiting you can't stop or trouble breathing after you return, go to your nearest emergency room and tell them about your surgery. Don't wait for an online reply.
- Once your weight stabilizes, we can coordinate excess-skin removal (body contouring), a separate procedure.
Obesity surgery in Turkey: common questions
Who performs the surgery?
Your surgeon is Op. Dr. Mesut Çaynak, a bariatric surgeon. He has been an SRC-accredited Master Surgeon in Metabolic & Bariatric Surgery since 2021 and has performed more than 3,800 obesity surgery procedures. Surgery takes place at ASV Yaşam Hospital, Antalya (JCI-accredited) or, in some cases, in Istanbul.
Am I eligible for weight-loss surgery?
Weight-loss surgery is generally considered for adults whose BMI and weight-related health conditions, such as type 2 diabetes or high blood pressure, make it appropriate. Eligibility also depends on your overall health and readiness for lifestyle change. A coordinator arranges a remote assessment, and the surgeon decides whether you qualify.
How much does gastric sleeve cost in Turkey compared with the US?
Your price in Turkey is a personal, written, all-inclusive quote after the surgeon reviews your case; it includes surgery, hospital stay, hotel and airport transfers. Flights are not included. NIDDK says weight-loss surgery in the US can cost $15,000 to $25,000 or more, depending on the procedure. Package prices are also listed on our price list page.
How long is the flight, and when can I fly home?
Most US itineraries connect through Istanbul, so flight time depends on your departure city. After surgery the surgeon decides when you are cleared to fly, usually around day 5–7. Longer itineraries can mean waiting a few extra days.
Is it safe?
Every surgery carries risks, including bleeding, infection and blood clots. Outcomes depend on a thorough pre-operative assessment, the surgeon's experience and follow-up care. We cannot promise results. Dr. Çaynak's team reviews your case first and can decline you if surgery isn't appropriate.
What about follow-up after I'm home?
You get 12 months of remote follow-up with a dietitian. Weight-loss surgery requires lifelong dietary changes and vitamin supplements. If you have severe symptoms at home, go to your nearest emergency room.
Do you offer revision surgery?
Yes. Revision surgery is for patients whose earlier weight-loss surgery needs to be corrected or converted. Whether it is possible, and what it costs, depends on your case, so there is no fixed price. Send your records and the surgeon's team reviews them before quoting.
What does the package cover?
The package covers tests, surgery, anesthesia, 3 nights in the hospital, hotel accommodation, dietitian visits, first-month medications, compression stockings and airport transfers. It does not cover flights. You get your exact quote in writing before you decide.
Gastric sleeve or gastric bypass: which is right for me?
Which one fits depends on your health: bypass is often considered when metabolic disease such as type 2 diabetes is present, and sleeve when obesity is the main issue. Dr. Çaynak explains his view in the video below, and your surgeon recommends one after reviewing your case.
