Bypass or sleeve

When a gastric bypass is the better choice

Most patients who write to us asking for a sleeve are right. Some are not, and it is the surgeon's job to say so before you fly rather than after.

You already have reflux

A sleeve raises pressure in the stomach and can make reflux worse; 10–20% of sleeve patients develop or worsen it long term. A bypass usually cures it. Significant reflux is the clearest reason to choose a bypass.

Your BMI is very high

Above a BMI of 50 a bypass tends to produce a larger and more durable loss. Sometimes the plan is a sleeve first and a bypass later; the surgeon tells you which.

Long-standing type 2 diabetes

Both operations improve diabetes, but the bypass's effect on blood sugar is faster and larger, often before much weight has gone.

A sleeve that stopped working

Weight regain after a sleeve, or reflux after a sleeve, is corrected by converting it to a bypass. This is the most common mini gastric bypass we do; the surgeon's own guide is mini gastric bypass Turkey.

A gastric band

Bands fail or erode. Removal and conversion to a sleeve or bypass is usually done in one operation; details and prices are on the revision surgery page.

When a sleeve is better

No reflux, a BMI of 35–50, no previous bariatric surgery: the sleeve is simpler, has no intestinal joins and is the first choice for most patients. See the gastric sleeve Turkey page.

The five days

Same process, same four nights

Day 1 · arrival, admission, bloods

Transfer from İzmir airport to the hospital; blood tests only.

Day 2 · tests, then surgery around midday

Ultrasound, echocardiogram, three specialist reviews. The bypass is laparoscopic and takes longer than a sleeve. Walking two hours later.

Days 2–5 · four nights in hospital

Bypass patients get the same stay as sleeve patients, not a shorter one. The joins are checked and you are watched.

Day 5 · home

English discharge summary, written diet plan, vitamins, airport transfer. Fifteen days of liquids, fifteen of soft purée, then solids. Vitamins for life.

Everything else, from flights to insurance to what happens if you need A&E in the UK, is identical to the sleeve and covered on the is gastric sleeve in Turkey safe page and in the surgeon's weight loss surgery Turkey overview.

Gastric bypass Turkey: questions

How much does a gastric bypass cost in Turkey?

With Op. Dr. Volkan Arayıcı a gastric bypass or a mini gastric bypass is £2,999, all-inclusive: tests, operation, four nights in hospital, companion, transfers, interpreter, medication and twelve months of follow-up. Flights are the only extra.

Sleeve or bypass: which should I have?

The surgeon decides from your details, not from what you ask for. In general: significant reflux, a very high BMI, long-standing type 2 diabetes or a previous failed sleeve point to a bypass. Otherwise the sleeve is simpler and is the first choice for most patients.

What is the difference between a gastric bypass and a mini gastric bypass?

Both create a small stomach pouch and re-route the small intestine. The Roux-en-Y bypass has two joins; the mini (one-anastomosis) bypass has one, is quicker and is often used for revisions. The surgeon chooses between them for you; the price is the same.

Is a bypass riskier than a sleeve?

Slightly, because there are intestinal joins. In an accredited centre the 30-day mortality is still around 0.2%. It is also why we do not shorten the hospital stay for bypass patients: four nights, the same as a sleeve.

Can a gastric bypass be reversed?

Technically yes, but it is rarely done and never lightly. Treat it as permanent. What it can do is be revised if needed; a sleeve can also be converted to a bypass later, which is the most common revision we do.

I had a gastric band. Can it be converted?

Yes. Band removal and conversion to a sleeve is £3,500, to a bypass £3,800, usually in one operation. Band removal on its own is £2,000. More on the surgeon's site: gastric band removal and conversion.

What about weight regain after a sleeve?

A sleeve that has stretched, or reflux that has become unmanageable, can be converted to a bypass. That is revision surgery, £3,500 all-inclusive, with the same four nights in hospital.
