Almost everyone researching bariatric surgery starts with the same question: am I a candidate? It is not a question the internet can answer for you. Candidacy is not established by looking at one number. It is the conclusion of an assessment carried out by several specialists working together.
What follows is a general outline of what that assessment considers. The aim is to make the process understandable, not to tell anyone that they qualify or do not. You can see the full range of procedures on our obesity treatments page.
One point is worth making at the start: bariatric surgery is not a cosmetic procedure. It is a treatment used in the management of metabolic disease, with structured preparation before it and structured follow-up after it. The assessment therefore works differently from a cosmetic enquiry.
International guidelines describe, in broad terms, when bariatric surgery can be considered. These are a starting point for discussion, not a checklist to score yourself against.
BMI on its own is not a sufficient criterion. Two people with an identical BMI may receive different recommendations. Read these thresholds as the beginning of a conversation rather than a promise.
BMI is prominent because it is easy to calculate, but it says nothing about muscle mass, where fat is stored or the metabolic picture behind it. An assessment usually reads these together:
Together these describe a metabolic burden rather than a weight target. Two people with the same BMI can be advised differently once these findings are laid side by side.
The assessment has another side to it. In some situations the surgical team will not recommend an operation, or will ask for another process to be completed first. The most common reasons include:
Most of these are not permanent barriers. Several can be treated, after which the assessment can be repeated. The purpose is to be confident that surgery can be performed under safe conditions.
That answer usually means the order has changed, not that the door has closed. A preparation period is defined, and the assessment is repeated at the end of it. Common steps include:
Which of these are asked for, and for how long, varies between patients. An unexplained refusal deserves questioning — and so does an acceptance that asks for no preparation at all.
The decision does not rest with one doctor. Bariatric surgery is a field where several disciplines work in parallel.
| Specialty | What it assesses |
|---|---|
| General surgery | Surgical suitability and choice of procedure |
| Endocrinology | Metabolic status, thyroid function, diabetes management |
| Anaesthesiology | Anaesthetic risk and airway assessment |
| Dietetics | Eating patterns and the post-operative nutrition plan |
| Psychiatry or psychology | Eating behaviour and readiness for the programme |
| Gastroenterology | Endoscopic assessment and stomach health |
A typical preparation includes blood tests, hormone panels, upper gastrointestinal endoscopy, abdominal ultrasound and cardiac and pulmonary evaluation. Where sleep apnoea is suspected, a sleep study may be requested. These results influence both the candidacy decision and the choice of procedure.
At Medicape Health, bariatric cases are carried out with our contracted partner in Adana, Private Medline Adana Hospital, which holds JCI accreditation. The assessment is made jointly by the hospital's surgical team and the relevant specialists.
For patients travelling from abroad the assessment splits in two. Knowing where the line falls makes both your length of stay and the documents you need clearer.
| Stage | What it covers |
|---|---|
| In your own country | Recent blood tests, a list of your medication, reports on chronic conditions, a sleep study if you have had one, and records of previous operations |
| In Adana | Clinical examination, endoscopy, abdominal ultrasound, anaesthetic assessment and, where indicated, cardiology and pulmonology review |
The dates on tests done at home matter; results that are too old are repeated. Bringing documents in English, or with a translation, makes it considerably easier to complete the assessment on the first day.
Once candidacy is established, a second question follows: which procedure? That answer is not standard either. It depends on BMI, related conditions, a history of reflux, previous abdominal surgery and endoscopic findings.
These options may look interchangeable from the outside, but each answers a different clinical situation. Only the team that examines you can say which of them is worth discussing in your case. Choosing a procedure in advance and asking the team to perform it reverses a sequence that works better the other way round.
Bariatric surgery is a starting point, not a finish line. It changes stomach volume and some hormonal responses. It does not change eating habits, activity levels or the behaviour behind them. Long-term outcome depends on the routine built after the operation.
That routine typically involves a staged nutrition programme, vitamin and mineral supplementation that may be lifelong, regular blood tests and scheduled follow-up appointments. No surgical technique substitutes for these steps. This is why dietetic and psychological support deserves as much attention in your pre-operative conversations as the surgical technique itself.
A sound decision process is not a fast one. At the end of the assessment you should receive, in writing, an explanation of the proposed procedure, the preparation stages, the length of hospital stay, the possible risks and the follow-up plan. Consent given without a discussion of risk is incomplete consent.
Seeking a second opinion is a normal part of this. If you want to share your test results with another centre, that is a reasonable request and should be treated as one. Feeling rushed, having questions brushed aside, or being given a guaranteed outcome are all signals to slow down.
Here the choice rests on the whole structure rather than on one recognisable name. The points worth asking about are:
A team that guarantees an outcome, avoids discussing risk or presses you to decide quickly is a warning sign in any country. A good consultation describes the period after surgery in the same detail as the operation itself.
BMI is one part of the assessment. Being above a threshold does not mean surgery is appropriate for you, and being below one does not automatically close the door. The decision comes from reading test results and examination findings together.
It usually begins with a remote review of your existing medical records and laboratory results. That first look is preliminary. The decision is confirmed after examination and completed testing once you arrive in Adana.
Before discharge you receive a written nutrition programme, a supplement plan and a follow-up schedule. Contact continues remotely after you return home, but having your blood tests done on time remains your responsibility.
No. Outcomes vary between individuals and depend on the starting picture, related conditions and adherence afterwards. Treat any centre that promises you a specific figure with caution.
