Best Gastric Sleeve Clinic in Turkey — how to tell a safe one from a cheap one
Every clinic calls itself the best. None of them define the word. This page does: seven checks you can verify before you pay anything — who holds the scalpel, where you sleep after surgery, and who pays if something goes wrong. Apply them to us, and to everyone else you are considering.
Send your height, weight and age and I will tell you honestly whether we are the right clinic for your case — including when we are not.
The seven checks
How to identify the best gastric sleeve clinic in Turkey
"Best" is not a feeling, and it is not a review score that a clinic paid for. It is seven things you can ask about and get a written answer to before you commit a penny. Below is each check, what a good answer sounds like, and the answer that should end the conversation. Send them to us — and to every other clinic on your shortlist. The one worth choosing will not hesitate on any of the seven.
Who actually holds the scalpel?
Ask: name the surgeon, their annual case volume, and their society membership.
A named surgeon, an IFSO membership and a four-figure case count. Op. Dr. Volkan Arayıcı has performed more than 5,000 bariatric operations, has done nothing else since 2014, and operates on every patient personally. If you are looking for the best doctor for gastric sleeve — or the best gastric bypass surgeon Turkey can offer — this is the only question that genuinely narrows the field.
Red flag: "our team of expert surgeons", with no name attached.
Where do you sleep after surgery?
Ask: how many nights in a hospital, and how many in a hotel?
Four nights in hospital, from landing to discharge, three of them after the operation. A hospital bed costs at least three times a hotel room because it includes overnight nursing and continuous monitoring — which is exactly why it is the first thing a cheap package removes.
Red flag: discharge to a hotel the day after surgery, described as "comfortable recovery".
Is there an intensive care unit in the same building?
Ask: which hospital, which accreditations, and where is the ICU?
A named hospital holding JCI and TEMOS accreditation, with intensive care on site. Any clinic claiming to be the best bariatric clinic Turkey has should be able to answer this in one sentence, because the accreditation is either on the wall or it is not.
Red flag: a "partner hospital" that changes depending on the week.
Who has to clear you before surgery?
Ask: which specialists sign off, and what happens if one says no?
Cardiology, pulmonology and anaesthesia each assess you separately after your bloods and ultrasound. If any one of them declines, the operation is postponed — no negotiation. That answer costs a clinic money, which is why so few give it.
Red flag: tests done on the morning of surgery, as a formality.
What exactly is in the package — and what is not?
Ask for the inclusions and the exclusions in writing, before you book.
Tests, surgery, hospital stay, transfers and twelve months of follow-up inside the price; flights outside it. You can read our full breakdown on the all-inclusive price page — including the line most clinics leave out.
Red flag: a headline price, then a theatre fee or "anaesthetist contribution" on arrival.
Who pays if there is a complication?
Ask it in exactly those words, and read the answer twice.
We do. Treating a complication costs you nothing extra — no second invoice, no charge for extra days, no bill for a return to theatre. A clinic that charges again when things go wrong has moved the risk onto the patient, and the price you were quoted was never the real price. We publish our complication and mortality figures rather than describing ourselves as safe.
Red flag: silence, or "that is what your travel insurance is for".
Who looks after you once you are home?
Ask: for how long, by whom, and through which channel?
Twelve months of follow-up by video call and WhatsApp, with the surgeon himself and a dietitian — not a sales coordinator. The first year is when weight regain is prevented or created, and a clinic that disappears after discharge has only sold you an operation, not a result.
Red flag: aftercare that ends when your flight lands in the UK.
Apply this to us as well. These seven checks are not a sales page dressed as advice — they are the questions we would want a member of our own family to ask. If another clinic answers all seven as clearly as we do and costs less, choose them. What you should not do is pick a clinic on price alone and discover the missing answers afterwards.
The access test
Three things the best gastric sleeve clinic in Turkey will let you do before you pay
Accreditations and case numbers tell you what a clinic is on paper. These three tell you what it is in practice — and they are what separates a surgeon-led practice from an agency with a medical partner. Each costs nothing to check and the answer arrives within a day. Run them on us, and on everyone else claiming to be the best bariatric clinic Turkey has.
Speak to the surgeon who will actually operate — before you book
Not a coordinator, not a patient adviser, not "our medical team". The person who will hold the instrument, on a call or on WhatsApp, before any money changes hands. Ask about your own case and see whether the answers are medical or commercial.
Many agencies simply cannot arrange this, because the surgeon is contracted per operation and assigned days before you fly. Some will not even give you a name — and a claim to be the best weight loss surgery clinic Turkey has does not survive that question. Whether you are looking for the best doctor for gastric sleeve or the best gastric bypass surgeon Turkey can offer, the rule is the same: no name, no booking.
Find the surgeon's own account — and talk to the patients on it
A surgeon who operates every week has an account of their own, with their own name on it, showing their own work over years. Not a clinic brand page, not a marketing agency's feed. It is one of the few places you can see continuity: the same surgeon, the same hospital, the same patients returning at six and twelve months.
More usefully, you can message those patients yourself. They do not work for us and have no reason to answer carefully. Dr. Arayıcı's account is @op.dr.volkanarayici — scroll it, pick anyone, and ask what the week in İzmir was actually like. We also publish written accounts in patient experiences from İzmir.
Ask whether there is a patient group — and whether the surgeon is in it
Our patients share a WhatsApp group, and Dr. Arayıcı is in it. Questions get answered by the surgeon rather than by a support script, and patients answer each other — what the second week of the liquid phase really feels like, which vitamins are easiest to get in the UK, what to expect at month four. Nobody moderates that into a marketing message.
This is an uncomfortable thing for a clinic to offer, because unhappy patients are in the group too. That is exactly why it is worth asking about. A practice confident in its outcomes puts its patients in a room together; one that is not keeps every conversation one-to-one, with a coordinator in the middle.
Run these three on every clinic you are considering. They take an afternoon and they are almost impossible to fake: a surgeon cannot invent five years of operating history on an account, and an agency cannot put you in a room with patients it never followed up. Any gastric sleeve turkey best clinic shortlist that survives all three is a shortlist worth trusting. Whatever you decide about us, do not book anywhere that fails every one of them.
The eighth check
A good clinic never asks you for money twice
Most patients worry about the headline number. The problem is rarely the headline number. It is the small charges that appear once you have landed, when you are tired, in a foreign country, and in no position to argue about forty euros. That drip is how a quoted package quietly becomes something else — and it is the clearest single signal of how a clinic treats the people it has already been paid by.
✕Things you will never be invoiced for here
- An extra night in hospital, if your recovery needs one
- Medication, fluids or dressings during your stay
- Protein shakes and post-operative supplements — not one of them, not at any point
- A repeat blood test, ultrasound or specialist review before surgery
- A second consultation, or a longer one
- Transfers, whichever day you actually fly
✓And if a complication occurs
Every cost of treating it is carried by the clinic and the surgeon. Extra days on the ward, intensive care if it were ever needed, a return to theatre, additional medication — all of it. There is no threshold, no excess, and no conversation about who is responsible.
This is not generosity. It is the only arrangement in which the clinic and the patient want exactly the same thing. When a complication costs a clinic money, that clinic has a permanent financial reason to operate carefully, staff its ward properly, and keep you in a hospital rather than a hotel. When the patient pays, it does not.
Ask for this in writing before you travel. Not "is it all-inclusive" — every clinic says yes to that. Ask instead: what specifically could I be asked to pay for after I arrive? A clinic that answers with a short, confident list is being honest with you. One that answers vaguely has left itself room. Our full breakdown of what is and is not covered sits on the all-inclusive price page, and it has not changed in years.

What patients say — unedited
What patients actually said about the best gastric sleeve clinic in Turkey
Every quote below is copied verbatim from our public Trustpilot profile — 160 reviews, rated 4.9 out of 5 — typos included. We have not tidied them up, because tidy reviews are the ones nobody believes. Anyone advertising the best weight loss surgery clinic Turkey can show you a wall of five-star quotes; what matters is whether you can open the source and read the rest of them yourself. Ours is public, so you can.
Each one carries a line explaining what it confirms, because a review that only says "amazing" tells you nothing about whether this is the best gastric sleeve surgery Turkey offers or simply a well-run marketing department.
Confirms check 04 — pre-operative clearances
"Unbelievable treatment throughout my operation and in the hospital afterwards. Then for months after I was messaged to see how I was getting on. The main part I really appreciated was the tests they did before my operation. I've had many operations since I was a kid and the tests before this op was a lot more than any other operation I've had in the uk."
Confirms the third access test — the patient group
"Fantastic communication beforehand with his Team via WhatsApp! Nice WhatsApp group for previous and curren clients to exchange experiences and questions. Great experience iverall! Was there in August 2023 for a gastric sleeve! Felt very well taken care of… Very re-assuring for this high anxiety lady. Aftercare was great as well."
On being accepted after another company refused
"Dr Volkan allowed me to have an amazing experience after a traumatic start. Mustafa came and picked me up from a company I had previously gone with that said they couldn't do it due to medication. Dr Volkan didn't hesitate and reassured me that my surgery could go ahead with the correct help."
On the result seventeen months later
"I had my gastric sleeve surgery in Dec 2022, I had no complications and I am now 17months post op and I've lost 9st… The booking process was really simple and they accommodated my companion too where they could sleep in the same room with two single beds in there."
An honest account of the pain — and of seeing the surgeon
"When I awakened after the surgery the pain is intense due to the gas the put inside you for the surgery but this soon goes away. The key is walking to eleviate the pain. I am so glad I chose Dr Volkan and in 3 weeks I have lost 2.5 stone… Dr Volkan is a great guy and will see you 3 times in total."
On reaching the best doctor for gastric sleeve directly
"The Doctor is great!! He is 24/7 online for his Patient's. When you have a Question you get a Answer before the OP and after the OP. This is unique! I have never seen before a Doctor like him."
Why these six, and not the glowing ones. Two of them describe the WhatsApp group and the pre-operative testing without being prompted — the same claims made higher up this page, confirmed by people with nothing to gain. One describes real post-operative pain, which no clinic would ever script. One describes being taken on after another company turned her away. Run the same test on any gastric sleeve turkey best clinic shortlist you are holding: open the review source, ignore the adjectives, and look only for specifics that could be checked. That is how you separate the best bariatric clinic Turkey has from the one with the largest advertising budget — and it works equally well whether you are choosing a sleeve, weighing up the best bariatric clinic Izmir can offer, or looking for the best gastric bypass surgeon Turkey has available.
The honest comparison
Should you wait for the NHS instead?
Before you spend another evening comparing clinics, answer this one first. If you meet the criteria and you can wait, the NHS route is the right one — and we would rather say that plainly than pretend otherwise. It is free at the point of use, your surgeon is regulated by the GMC, and your aftercare sits inside the same system that holds your records. No private clinic improves on that, and no honest page about the best gastric sleeve clinic in Turkey should begin anywhere else. The question is only whether those two conditions actually apply to you.
Who qualifies
- A BMI of 40 or above, or
- 35–40 with a serious obesity-related condition — type 2 diabetes, hypertension, sleep apnoea
- Lower thresholds apply if you are of South Asian, Chinese, Black African or African-Caribbean background
- Evidence that you have completed a tier 3 weight-management programme first
- Fit for anaesthesia, and committed to long-term follow-up
What that means in practice
The tier 3 programme alone commonly runs twelve to twenty-four months before you are even referred for surgery, and the wait for the operation itself follows after that. Reported total waits are measured in years rather than months, and they vary enormously depending on where you live.
Two groups fall through the gap most often: people whose BMI sits just under the threshold, and people who complete tier 3 but are then referred back into it. If either has happened to you, that is worth discussing before you conclude surgery is not available.
What nobody tells you about coming home
This is the part most clinics skip, so here it is. After surgery abroad your GP takes over routine monitoring — annual blood tests, vitamin B12, iron, folate and vitamin D. Most GPs will do this without difficulty; some are reluctant when the operation was performed privately overseas, and you should know that before you fly rather than after.
What makes it straightforward is paperwork. We send you home with a full discharge summary and operative note in English, addressed to your GP, listing exactly what was done and what monitoring you need. Hand that over at your first appointment and the conversation is usually a short one. Our own twelve months of follow-up runs alongside it, not instead of it — and if your GP wants to speak to the surgeon directly, that can be arranged. Ask about this paperwork wherever you go; the best bariatric clinic Turkey has to offer will hand it to you without being asked, and a clinic that cannot produce an operative note has told you something about its record-keeping.
If the NHS route is closed to you
Then the decision changes shape. It stops being NHS versus private and becomes which clinic — a harder question, and one the internet answers badly. Search for the best gastric sleeve surgery Turkey provides and you get a thousand pages saying the same four things. Search instead for the best weight loss surgery clinic Turkey advertises, or for the best doctor for gastric sleeve, or for the best gastric bypass surgeon Turkey can offer, and the wording changes while the promises stay identical. Everyone is excellent, everyone is award-winning, nobody defines the word.
That is why the seven checks above are written as questions rather than claims. They work the same whether you are narrowing a gastric sleeve turkey best clinic shortlist, weighing up the best bariatric clinic Izmir has, or choosing between two surgeons in Istanbul. Same questions, any procedure, any city — and the answers, unlike the adjectives, actually differ.
One thing to be clear about: the NHS will treat you if something goes wrong, whoever operated and wherever. Nobody is turned away at A&E for having had surgery abroad. Anyone who implies otherwise is using fear to sell you something.
Location matters more than you think
Best bariatric clinic Izmir: why the city changes the outcome
Almost every search for the best gastric sleeve surgery Turkey offers leads to Istanbul. That is not because the surgery is better there — it is because Istanbul is where the medical-tourism industry concentrated: the agencies, the call centres, the clinics that run forty patients through a theatre in a week. Volume is good for a business model. It is not automatically good for you.
We work in İzmir, on the Aegean coast, and the difference is structural rather than scenic. The practice is surgeon-led, not agency-led. There is no coordinator between you and the person operating — you message Dr. Arayıcı, he answers, and he is the one in theatre. In a high-volume Istanbul clinic, the person who sells you the package and the person who holds the instrument are rarely the same, and often never meet you together.
The practical side is easier than most patients expect. Consultations are held in Güzelbahçe, surgery takes place in a JCI- and TEMOS-accredited hospital in İzmir, and a private transfer meets you at İzmir Adnan Menderes Airport — a direct ride at the end of a long flight, not a two-hour crawl across a city of sixteen million.
İzmir at a glance
Surgeon continuity is the part you cannot buy back
If something feels wrong in month three, the question is not whether the clinic has a support line — it is whether the person who reads your message has any memory of your anatomy. Here, the surgeon who operated is the one who answers, for twelve months. That single fact is why patients comparing options for gastric sleeve turkey best clinic shortlists increasingly look outside Istanbul, and it is the reason our revision patients so often arrive from somewhere else entirely.
None of this makes Istanbul a bad choice by definition — there are excellent surgeons there, and we would say so to your face. It makes the clinic model the thing to examine, not the city on the brochure. Ask the seven questions above of any clinic in any city, and the answers will sort themselves out. If safety statistics are what you want rather than adjectives, we set ours out in how safe bariatric surgery in Türkiye actually is.
Straight answers
Choosing a clinic: frequently asked questions
Which is the best gastric sleeve clinic in Turkey?
No honest clinic can answer that about itself, so here is the useful version: the best gastric sleeve clinic in Turkey for you is the one that names its surgeon, keeps you in a hospital rather than a hotel, has intensive care in the same building, holds JCI or TEMOS accreditation, and covers the cost of treating a complication. Apply those five tests and the shortlist gets short very quickly. Our clinic in İzmir meets all five, and we would rather you verified that than took our word for it.
Who is the best doctor for gastric sleeve surgery in Turkey?
Judge a surgeon on three measurable things rather than on marketing: how many bariatric operations they perform a year, whether bariatrics is all they do, and whether they belong to the IFSO. Op. Dr. Volkan Arayıcı has completed more than 5,000 bariatric procedures, has practised nothing else since 2014, and is an accredited IFSO member. Any surgeon you are considering should be able to give you those three numbers without checking.
How do I check that a Turkish clinic is genuinely accredited?
Ask for the name of the hospital, not the clinic brand, then look that hospital up on the JCI and TEMOS registers yourself. Accreditation belongs to a building and a licence, not to a website. If a clinic gives you a "partner hospital" that changes depending on the week, or cannot say where the intensive care unit is, that is your answer. Our surgery takes place in a JCI- and TEMOS-accredited hospital in İzmir — ask me for its name and I will give it to you in writing, so you can check both registers yourself.
Is a cheaper clinic always a worse clinic?
No — but a cheaper package is always cheaper for a reason, and you are entitled to know which one. Prices fall because something was removed: nights in hospital, pre-operative clearances, original branded staplers, aftercare, or liability for complications. A clinic that can explain exactly where its saving comes from is worth considering. One that cannot is selling you a number, not an operation.
Will I be moved to a hotel after my operation?
Not with us. Our patients spend four nights in hospital, counted from the day they land to the day they are discharged, three of those nights after surgery. The transfer takes you from the airport directly to the hospital. A hospital bed costs at least three times a hotel room because it includes overnight nursing, monitoring and an on-site intensive care unit — which is precisely why it is the first thing a budget package removes.
How do I know the surgeon I message is the one who operates?
Ask for it in writing, and ask who performs the operation if that surgeon is unavailable on the day. In agency-led clinics the person answering WhatsApp is a coordinator and the operating list is assigned later. Here you message Dr. Arayıcı directly, he answers personally, and he performs every operation himself — it is not delegated to an assistant once you are under anaesthetic.
Do you accept patients who were operated on somewhere else?
Yes, and it is a large part of our work. Revision surgery is technically harder than a first operation because scar tissue changes the anatomy, so it belongs with a surgeon who performs revisions regularly rather than occasionally. Send us your original operation report if you have it, your recent blood work, and an endoscopy. If you cannot obtain the surgical report, the tests we run on arrival show us what we need.
Is it safe for UK patients to have surgery in Turkey?
It is as safe as the specific clinic you choose — which is the entire point of this page. The stories that reach the British press almost always involve the same pattern: an unnamed surgeon, discharge to a hotel, no accredited hospital, and no cover when something went wrong. Those are all things you can check before you book. Country of treatment is a far weaker predictor of outcome than the seven checks above.

Before you book anywhere
Do not trust us. Check us.
Everything on this page is written to be verified rather than believed. Take the seven questions, send them to us and to every other clinic on your list, and compare the answers side by side. If someone answers all seven as plainly as we do and costs less, go to them — that is a good outcome, and you will have chosen safely.
If you would rather start with your own case than with a checklist, send your height, your current weight and your age on WhatsApp. Dr. Arayıcı reads it himself and replies personally, usually the same day — with the procedure he would actually recommend, a fixed all-inclusive price, and an honest answer if he thinks you should wait, lose weight first, or be treated closer to home.
No deposit, no booking fee, and nothing to pay until the day of your operation. Asking questions costs you nothing at all.
