Gastric sleeve in Tunisia: eligibility, price and lifelong follow-up

The surgeon removes roughly two thirds of the stomach, taking the outer curve and leaving a narrow vertical tube running from the oesophagus to the outlet. Nothing is rerouted and no implant is placed: what is removed is removed, and what remains works in the normal order.

It changes two things at once, and the second is the one people underestimate. Capacity falls sharply, so a small volume of food produces a feeling of fullness. Appetite also falls, because the part of the stomach that is removed produces much of the ghrelin that drives hunger. Most patients describe the first year as the first time in their adult life that they are not thinking about food between meals. That effect is real and it is also not permanent at the same intensity — which is why the habits you build in that first year matter so much.

This needs saying plainly, because it is the question people ask last and should ask first. A sleeve gastrectomy cannot be undone. The part of the stomach that is removed is removed; there is nothing to put back and nothing to deflate or unclip.

What can be done later is a conversion — most often to a gastric bypass, where reflux or significant weight regain makes it the better option. That is a second operation with its own risks, not a reversal.

If the permanence of that is what is holding you back, there are reversible options, and they are genuinely different operations rather than weaker versions of this one: see the gastric band and the gastric balloon.

Four procedures are commonly discussed, and they are not four strengths of the same thing. They solve different problems and they fail in different ways.

Sleeve or bypass, in one sentence each

If you have significant acid reflux or a hiatus hernia, a bypass is usually the better operation, because a sleeve can make reflux considerably worse. If you have poorly controlled type 2 diabetes, a bypass often has the stronger metabolic effect. If neither applies, a sleeve is the simpler operation, with less rerouting and a lighter lifelong supplementation burden. Your surgeon decides this after the work-up, not from a page.

And what about Mounjaro, Wegovy and the other weight-loss injections?

This is now the first question most people ask, and it deserves a straight answer rather than a sales one.

GLP-1 and dual-agonist medicines genuinely work. They are not a weaker version of surgery and surgery is not a stronger version of them — they are different commitments. The medicines require an indefinite prescription, an indefinite cost and an indefinite supply, and weight regain after stopping is well documented. Surgery is one irreversible event followed by lifelong vitamins and blood tests. Some people are better served by one, some by the other, and some use the medication first and never need the operation. A clinic that tells you injections do not work is selling you something.

One safety point that is not optional. If you are taking any GLP-1 or dual-agonist medicine — semaglutide, tirzepatide, liraglutide, under whatever brand name — you must tell the surgeon and the anaesthetist before you travel, even if you stopped recently. These medicines slow the emptying of the stomach, which matters for a general anaesthetic, and anaesthetic societies have issued guidance on pausing them beforehand. Your anaesthetist will tell you for how long. Do not leave this off your medication list because it feels like a diet drug rather than a medicine.

Two prices, both for a five-day stay in Tunisia.

The price covers the consultation, the basic pre-operative work-up, the operation, the anaesthetic, the hospital stay, transfers, and the immediate post-operative follow-up. It does not cover your flights, the vitamins and supplements you will take from here on, or the blood tests and dietetic follow-up in your own country — and those are not an afterthought. Budget for them in the same conversation in which you budget for the operation, because they continue for the rest of your life.

Reimbursement where you live is a separate question. Several European systems fund bariatric surgery against their own criteria, but the waiting time runs from several months to more than a year, which is why most people looking at this page are looking abroad in the first place. Surgery paid for privately abroad is not usually reimbursed afterwards. Check with your own scheme before you book rather than after.

The work-up is not a formality and it is not there to sell you the operation. It exists to answer two questions: is this operation safe for you, and is it the right one.

• Nutritional assessment, which also establishes the baseline your later blood tests are measured against.
• Full blood work-up.
• Cardiac and respiratory assessment.
• A psychological opinion, in many cases. This is not a test you pass or fail; it is there because the operation changes your relationship with food abruptly and some people need support with that arranged in advance rather than discovered afterwards.

The pre-operative diet

You will be asked to follow a low-calorie diet for one to three weeks before surgery. The purpose is surgical rather than cosmetic: it shrinks the liver, which sits directly over the operating field, and a smaller liver makes a laparoscopic sleeve safer and easier. This is the part patients are most tempted to skip and the part the surgeon notices immediately. Follow it.

Nicotine in every form — cigarettes, vapes, heated tobacco, pouches — is stopped several weeks beforehand. It raises the risk of a leak at the staple line and of a clot, which are the two early complications that matter most.

• Your enquiry and a first opinion. Send your height and weight, your BMI, the weight-related conditions you have, your medication list and a summary of what you have already tried. You receive a first opinion and a quote within 24 to 48 hours. It is an opinion, not an approval.
• The work-up. Blood tests, cardiac and respiratory assessment, nutritional assessment and, in many cases, a psychological opinion, carried out where you live. The surgeon reviews the results before you book anything.
• The pre-operative diet. One to three weeks of a low-calorie diet to shrink the liver, plus stopping nicotine several weeks ahead.
• Arriving in Tunis. A member of the team meets you in the arrivals hall at Tunis-Carthage with a board showing your name, and takes you to your accommodation. Tell us immediately about a delayed flight or a missed connection; surgery is scheduled around your arrival, not the other way round.
• Consultations. You meet Dr Ayadi and the anaesthetist. Bring your full medication list, including anything taken for diabetes, blood pressure or weight — the injections included.
• The operation. 1 to 2 hours, laparoscopically, under general anaesthetic. Several small incisions rather than one large one.
• In hospital. Several days of monitoring. You will be asked to walk within hours of the operation, which is not enthusiasm on the staff’s part — it is the single most effective thing you can do against a clot. Expect shoulder pain from the gas used during keyhole surgery; it goes within a few days and surprises everyone who was not warned.
• Discharge. You leave with your operative report, your discharge prescription and your dietary protocol.
• Going home. You fly once the surgeon confirms you are fit to travel, and the follow-up starts the moment you land.

Two things to ask for before you leave the clinic

Your operative report, in English, in writing. It should say what was done, when, by whom and with what. This is the document an emergency department abroad will ask for if anything goes wrong, and the document your GP will want before taking on your follow-up. Keep a paper copy in your bag and a photograph of it on your phone.

Your prescription written in generic drug names with doses. Brand names differ between countries and a pharmacist in Manchester or Abu Dhabi may not recognise a Tunisian one. Ask for the generic name and the strength of every item, supplements included.

A sleeve gastrectomy is a routine operation in experienced hands and it is major abdominal surgery. Both of those are true, and a page that only told you the first would be useless to you.

Early risks

• A leak at the staple line. Rare, and the complication that matters most, because it needs treating quickly.
• Bleeding.
• Infection.
• Venous thrombosis — a clot in the leg or the lung. The risk is higher in this group of patients and higher again around a flight, which is why walking early and following the clot-prevention plan are not optional.

Later risks

• Stricture — a narrowing of the sleeve.
• Acid reflux, new or worsened. Covered in its own section below, because it deserves one.
• Nutritional deficiency, which is preventable and is the reason for lifelong supplements and blood tests.

Go to an emergency department the same day if you have any of these

• Fever.
• Abdominal pain that persists or is getting worse.
• Repeated vomiting, or being unable to keep fluids down at all.
• A fast heart rate. This one is easy to dismiss and is often the earliest sign of a leak — take it seriously.
• Breathlessness.
• Pain or swelling in one calf.

The honest risk of having this operation abroad is that the first two weeks, when these things declare themselves, are partly spent at home. That is managed rather than ignored: you leave with a named contact who answers, written instructions on what is normal, and your operative report. If you need to be seen urgently, be seen where you are — do not wait for a reply from Tunis — and tell us at the same time. Walk into the emergency department saying I had a sleeve gastrectomy on this date and hand over the report. That sentence and that piece of paper change how quickly you are assessed.

Eating returns in four stages, over several weeks, following the protocol you are given on discharge: liquids for the first days, then puréed, then soft, then normal food in small quantities. The stages are not arbitrary and moving through them faster than you are told is how people end up vomiting and back in hospital.

Three habits carry most of the long-term result: protein first at every meal, fluids between meals rather than with them, and eating slowly enough to notice fullness before you pass it. Your new stomach gives you very little warning.

Things nobody warns you about

• Hair loss between the third and sixth month. Common, distressing, and temporary. It reflects the speed of the weight loss, not a deficiency you have caused, and it regrows.
• Your usual medication may need changing. Treatments for type 2 diabetes and high blood pressure often need reducing, sometimes quickly, as your weight falls. That is done by a doctor, with monitoring — not by you, and not by stopping something because you feel better.
• Alcohol affects you differently. It is absorbed faster and reaches you harder at volumes that used to be nothing. Surgical societies also report a raised risk of problematic alcohol use after bariatric surgery. Either avoid it or treat it with considerably more caution than before, and talk to your doctor if it becomes a concern.

Fasting, including Ramadan

This comes up constantly and is rarely written down anywhere, so plainly: fasting after a sleeve is mainly a question of dehydration and protein, not of willpower. A small stomach makes it hard to take in enough fluid in a short eating window, and dehydration is the most common reason patients are readmitted in the first year. Most patients are advised not to fast during that first year, and to resume afterwards with a plan for fluids and protein across the hours when eating is permitted.

Islamic practice makes allowance for health, and whether that applies to you is a conversation between you, your doctor and your own religious adviser. It is not a decision for a clinic and we will not pretend otherwise — but do have the conversation before Ramadan rather than during it.

Yes, it is possible, and you should hear it from us rather than find out at year three.

A regain of around 10% of the weight you lost is expected in a proportion of patients, typically between two and five years after surgery. That is not failure and it is not a sign that the operation did not work — it is the known shape of the curve.

Three things drive it: the sleeve itself stretches somewhat over time, the strong early reduction in appetite fades, and grazing and liquid calories pass through a small stomach without ever triggering fullness. The first is anatomy. The other two are the reason the dietetic follow-up matters more in year two than in week two, when everyone is still paying attention.

What helps is acting early. A few kilos regained at eighteen months is a conversation about habits. The same pattern left until year five is a conversation about revision surgery. If the weight starts moving back up, say so at the next review rather than waiting until you feel you have something to confess.

A sleeve generally improves fertility and improves the outlook of a pregnancy, and it also sets a timetable.

Wait 12 to 18 months after surgery before conceiving. That is the period of rapid weight loss, and it is a poor environment for a pregnancy: nutritional intake is low, weight is falling fast, and the deficiencies that supplements are preventing are at their most likely. Once weight has stabilised, pregnancy after a sleeve is generally safer than pregnancy at the weight you started from.

Contraception, which catches people out

Fertility often returns quickly as weight falls — sometimes in women who had been told conceiving was unlikely, and sometimes within months. Effective contraception should be agreed before the operation, not after. Ask your doctor specifically whether your current method stays reliable after bariatric surgery; the answer differs between methods, and oral contraception is the one worth asking about.

If you do become pregnant

Tell the midwife or obstetric team at the first appointment that you have had a sleeve gastrectomy, and bring the operative report. Supplementation and monitoring are adjusted in pregnancy, and the team cannot do that if they do not know.

Significant weight loss leaves skin that does not retract, most often at the abdomen, the arms, the inner thighs and the breasts. How much depends on how much weight was lost, over how long, on your age and on your skin — and not on anything you did wrong.

Reconstructive surgery is considered once your weight has been stable, generally 12 to 18 months after the sleeve. Operating earlier means operating on a body that is still changing, and the result changes with it.

Two honest points before you plan for it. Body contouring after major weight loss is rarely a single operation — it is usually staged across more than one procedure and more than one trip. And it trades loose skin for permanent scars, which are long and which some people find a harder trade than they expected. Most health systems and insurers treat it as cosmetic and do not fund it.

The procedures most often discussed at that point: tummy tuck, arm lift, thigh lift and breast lift.

Most people arrive at this page because of a waiting list or a price, so here is what those two things actually look like.

• Time. Several European systems fund bariatric surgery against their own criteria, and the wait runs from several months to more than a year. That wait is the single most common reason patients look abroad.
• Travel. Tunis is a direct flight of 1 hour 30 to 3 hours from most of western Europe, into Tunis-Carthage. EU and Swiss nationals do not need a visa. Every other passport has its own requirements, which change — check yours against your own government’s guidance before booking, and tell us early if you need supporting documentation.
• One organised trip. Consultations, the operation, the hospital stay and transfers are arranged together, with a coordinator who knows your file.
• English and French throughout, including with the anaesthetist.

And the thing to weigh against all of it

Bariatric surgery abroad works well for people who have their aftercare arranged before they fly, and badly for people who have not. That is the honest comparison, and it is not about Tunisia — it would be the same sentence about any country. Read the follow-up section above, have the conversation with your GP, and then decide.

Bariatric surgery at ServiHealth is carried out by Dr Sofiene Ayadi, a surgeon specialising in obesity surgery, at the Clinique Internationale Myron in Tunis.

You meet him in person before the operation, alongside the anaesthetist. That consultation is where your work-up is reviewed, where the choice between a sleeve and a bypass is settled, and where you are told what this operation will and will not do for you. The decision on indication and technique belongs to the surgeon; the decision on whether to proceed belongs to you, and it is taken after that conversation.

Dr Ayadi and the ServiHealth team remain reachable for remote follow-up through the first six months after you go home.

Send with your enquiry

• Your height, weight and BMI, and your weight history in outline.
• Weight-related conditions: type 2 diabetes, high blood pressure, sleep apnoea, joint problems.
• Your full medication list — including any GLP-1 or weight-loss injection, and any antacid or stomach-acid medication, even bought over the counter.
• Any previous abdominal surgery, including a caesarean section, a hernia repair or a previous bariatric operation.
• What you have already tried, and for how long.

Arrange before you book, not after

• Talk to your GP. Will they request and review your annual bariatric blood tests? Will they prescribe your supplements, or are you buying them? Get the answer now.
• Find a dietitian or nutritionist where you live, for the first year at least.
• Budget for the aftercare, not only the operation: supplements for life, and blood tests from here on.
• Arrange travel insurance that covers you abroad, and read what it says about planned surgery.
• Book 2 to 3 weeks away from work and a return flight you can move.

Before you fly

• Complete the work-up: bloods, cardiac and respiratory assessment, nutritional assessment, and a psychological opinion where asked for.
• Follow the pre-operative diet for the one to three weeks you are given. It shrinks the liver and it makes your operation safer.
• Stop nicotine in every form, several weeks ahead.
• Agree contraception in advance if that applies to you.

Before you leave the clinic

• Your operative report in English, on paper and photographed on your phone.
• Your prescription in generic drug names, with doses.
• Your dietary protocol, in writing.
• The name and the number of the person you call if something is wrong at two in the morning.

One last thing. Take a photograph of your operative report and keep it where you can find it in five years, in another country, on another phone. The number of patients who cannot say what operation they had is larger than you would believe, and it is the single most avoidable problem in this entire field.
