Gastric sleeve UK vs Turkey: the honest comparison

If you qualify on the NHS and can wait, wait. If you cannot, here is how the UK private route and İzmir really differ.

This page is written by a surgeon in Turkey, so read it critically. Where the NHS is the better answer, it says so.

The NHS route

Check the NHS first

NHS bariatric surgery is free at the point of use and your follow-up stays inside the system that will look after you for the rest of your life. If you qualify and can manage the wait, it is very often the right choice.

What you generally need

A BMI of 40 or above, or 35 and above with a serious weight-related condition such as type 2 diabetes, high blood pressure or sleep apnoea, and evidence that other methods have been tried.

Tier 3 comes first

Most areas require a specialist weight-management programme before a surgical referral. Only after that do you join the list for the operation itself.

Why people leave the pathway

Three reasons, in our experience: they fell just outside the BMI criteria, their area's wait ran into years, or their health was getting worse while they waited.

Where the money goes

Why the same operation costs a quarter of the UK price

The operation is identical: the same staplers, the same laparoscopic technique, hospitals accredited to the same international standards. What differs is the cost of the building, the staff and the insurance around it.

What differs between Turkish clinics is more important than what differs between countries. A package at £2,100 with one night in hospital and three in a hotel is not the same product as £2,499 with four nights on a ward, and the UK press cases almost always involve the first kind.

What you give up by travelling is real and you should weigh it: no in-person follow-up, a flight home on day five, and a GP who may not have been involved. What we put against that is twelve months of direct contact with the surgeon, a full English discharge summary and corrective surgery at no charge if a complication falls to us.

Before you decide

Five things to do in the UK first

Ask your GP whether you qualify

And what the current wait is in your area. If the answer is “yes, and about a year”, think hard before paying for anything.

Tell your GP you are considering surgery abroad

Ask whether they will do your routine blood tests afterwards. Most will, but ask.

Get your price and your operation in writing

From any clinic, here or in Turkey: named surgeon, nights in hospital, what is excluded.

Buy the right insurance

Your GHIC does not cover Turkey and holiday policies exclude planned surgery. You need cover for elective treatment abroad, including repatriation.

Run the safety checklist

The six points on the is gastric sleeve in Turkey safe page take ten minutes and apply to every clinic, including ours.

Questions and answers

How long is the wait for a gastric sleeve on the NHS?

It varies widely by area. You usually have to complete a tier 3 weight-management programme before a surgical referral, and then join the waiting list for surgery itself. Many patients are in the pathway for well over a year, and often two or more.

Do I qualify for a gastric sleeve on the NHS?

The general criteria are a BMI of 40 or more, or 35 to 40 with a serious weight-related condition such as type 2 diabetes or high blood pressure, after other methods have been tried. Lower thresholds can apply for recent-onset type 2 diabetes and for some ethnic backgrounds. Your GP can tell you where you stand.

How much does a private gastric sleeve cost in the UK?

Typically between £7,000 and £14,000, with most standard packages around £10,000. That usually includes UK-based follow-up for about two years.

Why is Turkey so much cheaper?

Lower hospital, staff and running costs, not a different operation. The staplers, the technique and the accreditation standards are the same. What does differ between Turkish clinics is how many nights you spend in hospital.

Is the NHS route better than going to Turkey?

If you qualify and can wait, it is very often the right choice, and the surgeon will tell you so. It is free and your aftercare sits in the system that will look after you for life. Most of our UK patients come because they fell just outside the criteria or could not wait.

Will the NHS look after me if I have surgery abroad?

For anything acute, yes: you go to A&E and you are treated like any other patient. Routine bariatric follow-up after private surgery abroad is not guaranteed, which is why we provide twelve months of follow-up and a full English discharge summary for your GP.

Should I tell my GP?

Yes, before you travel. Ask whether they will do your routine blood tests afterwards and give them the discharge summary when you return.

Not sure which route is right for you?

Send your height, weight, age and where you are in the NHS pathway. The surgeon gives you a straight answer, including “stay on the list” when that is the right one.
