Obesity surgery in Turkey — common questions
Who performs obesity surgery through NexWell?
Bariatric procedures are performed by a high-volume bariatric and general surgeon at internationally accredited Istanbul hospitals. Content is reviewed by Dr. Umut Rıza Gündüz, a general and bariatric surgeon focused on obesity and metabolic surgery. Surgeon volume and experience are among the most important safety factors in bariatric surgery.
Am I eligible for obesity surgery?
Bariatric surgery is generally considered for adults with a BMI of 40+, or 35+ with weight-related conditions such as type-2 diabetes, hypertension, or sleep apnoea. Eligibility also depends on overall health and readiness for lifestyle change. A NexWell coordinator can arrange a remote assessment to confirm whether you are a candidate.
How much does obesity surgery cost in Turkey?
Gastric sleeve in Turkey starts from around $3,200 all-inclusive and gastric bypass slightly more — roughly 60–70% less than the UK, with hospital stay, hotel, transfers, and aftercare bundled in. The exact price depends on the procedure and your case.
Is bariatric surgery in Turkey safe?
When performed by an experienced, high-volume surgeon at an accredited hospital, bariatric surgery has well-established safety. The key factors are proper pre-operative assessment, surgeon experience, and structured aftercare. NexWell coordinates only with accredited hospitals and experienced bariatric surgeons, and supports you through follow-up after you return home.
What about aftercare and follow-up?
Bariatric surgery requires lifelong dietary changes and vitamin supplementation, plus structured follow-up. Your package includes aftercare guidance, and your NexWell coordinator remains available for remote follow-up. We also coordinate body-contouring options such as excess-skin removal once your weight has stabilised.
More information
What a clinic should ask you for before surgery
None of this is legally compulsory, and that is exactly what makes it useful. What a clinic asks for when nothing forces it tells you how that clinic works. So read the list twice: once as the work-up you should have done, once as a measure of the clinic in front of you.
Blood tests
These are read together, as one picture, not ticked off one by one. A team planning surgery without a recent set of them is planning half-blind.
Complete blood count (CBC / hemogram)
The overall picture of your blood: anaemia, signs of infection, platelet levels. It is the baseline any surgical team wants in front of it before starting.
Blood glucose
Blood sugar affects how you heal and how prone you are to infection after a procedure. What is needed is a current reading. A result from three years ago tells nobody anything.
Coagulation tests (PT, INR)
How quickly your blood clots. The team plans around bleeding on the basis of it, and all the more so if you take blood thinners.
Infection safety
These three are taken as routine, not as a judgement about you: they protect you, the team, and the patient who comes after you. What a result means belongs to your doctor, not to a search engine.
HBsAg (Hepatitis B)
Screening for hepatitis B. Theatre scheduling and instrument handling are organised around it.
Anti-HCV (Hepatitis C)
Screening for hepatitis C. It often goes years without symptoms and shows up only in the lab.
HIV 1/2
Standard screening before an operation. A serious clinic asks for it in order to plan safely, not in order to judge you.
Bisphosphonate use
Bisphosphonates are bone medicines, most often taken for osteoporosis, sometimes as part of cancer treatment. In the jaw they matter more than anywhere else: in people who take them, or who took them in the past, an implant or an extraction carries a risk of osteonecrosis of the jaw (MRONJ). The effect on bone can outlast the final dose, so a course you finished years ago still counts.
This is not something you book at a lab. It is a question about your medication history. If you take a bisphosphonate, or ever have (under any brand name, as tablets or as an infusion), say so before a treatment plan is written, not after. Bring the name of the drug and, if you know them, the dates. A clinic that never asks what you take has not assessed you.
A good clinic asks you for all of this on its own. If yours doesn't, ask why. The side that writes your treatment plan should not be the only side judging it. This list is the simplest way to keep that judgement in your own hands.
This section is not a medical assessment and does not prescribe tests. Which of these apply to you, and what any result means, is a conversation with your own doctor and with the clinic performing the procedure.
