Not medical advice. Talk to your own doctor before you book. Gastric sleeve, bypass and band make the stomach smaller (a gastric balloon does too, without surgery). It is major surgery with follow-up for life: UK surgeons' societies urge caution with surgery abroad, mainly because the follow-up at home is often missing.

The rules in Croatia
Croatia is in the European Union: EU patient-safety rules apply there. Refunds under the EU rules on cross-border healthcare are only for residents of the EU and the EEA, and only for care their own health system would pay for at home: not for residents outside the EU and EEA, such as the UK, the US, Canada, Australia, New Zealand or Saudi Arabia.
The trip
- One trip, but a long one: at least 10 days before flying home, then two years of specialist follow-up you must arrange at home before you go. If you use a CPAP machine for sleep apnoea, contact the airline well before the flight about medical equipment, carry the machine in your hand luggage (not in the hold), and ask your sleep team for a letter about it (NHS).
- The CDC advises not flying for 10 days after chest or abdominal surgery.
- Leaving hospital: You can usually leave hospital one to three days after surgery.
- No heavy lifting or strenuous exercise: Increase your activity gradually, as your exercise plan says: the NHS says to start returning to normal activities after 4 to 6 weeks. Ask the surgeon in writing when you can lift, go back to the gym or to a physical job.
- Earliest flight home: Avoid flying for 10 days after abdominal surgery.
Your dates in the recovery planner · The full cost of the trip
We publish no price for weight-loss surgery in Croatia: we have no source independent of clinics for it. Ask the clinic for a written quote, with what it includes, and enter it in the true cost tool.
Red flags
- No questions about your BMI, health conditions or eating history before a date is offered.
- Surgery booked within days of first contact, or several procedures combined to lower the price.
- No named surgeon, or no plan for what happens if you have a complication after you fly home.
- Packages that send you home before 10 days.
- The clinic says no psychological assessment or dietitian is needed before the operation.
- A package promising you can go back to work after one week.
- Follow-up limited to a few months of chat or messaging support: the NHS describes follow-up in a weight-loss surgery clinic for at least the first 2 years.
- Being told you can keep taking a blood thinner as usual, without a written plan from the surgical team and your own doctor.
- A clinic that tells you not to involve your specialist, your transplant team or your doctor at home.
- No blood tests or other checks before an operation under general anaesthetic: a pre-operative assessment, often with blood tests, comes first (NHS).
Ask the clinic
- Who is the surgeon, how many of these operations do they do a year, and where are they registered?
- Which operation exactly, and why that one for me?
- Is a dietitian and a psychological assessment part of the preparation?
- How many nights in hospital, and who sees me before I fly?
- What follow-up is included for two years, and what happens if I have a leak or another complication at home?
- Who looks after me in the first 24 hours after the anaesthetic, and what do I tell the anaesthetist? Tell them about every health condition (for example sleep apnoea) and every medicine.
- I have a health condition or take medicines: has the anaesthetist seen this before the day, in writing?
- I take the combined pill or HRT, or I smoke or vape: what should I stop, and how long before the operation?
- I take insulin or other diabetes medicines: who lowers the doses right after the operation, and who adjusts them once I am home?
- I take a GLP-1 medicine (semaglutide, tirzepatide): when should I stop or keep it before the anaesthetic?
- I had weight-loss surgery before (a band or a sleeve): what does the revision involve, one or two operations, and how many revisions do you do a year?
- I have reflux or heartburn and take medicines for it: does it change which operation you advise?
- I take medicines every day (antidepressants, thyroid, the pill): who reviews the doses and forms after the operation, and who follows my mental health at home?
- When can I drive and lift again? I drive for work (and my diabetes medicines may change).
- I take thyroid hormone (levothyroxine): who checks my dose with blood tests in the months after surgery, here or at home?
- I take a blood thinner (for example apixaban or warfarin): who plans stopping or bridging it with my own doctor or cardiologist, and from which day?
- I have a bleeding disorder (for example von Willebrand disease or haemophilia), or I bruise or bleed easily: who plans the operation with my haematologist, and which blood tests do you do before it? (NHS: tell your specialist team before surgery or dental treatment)
Back home
🇬🇧 If you live in the United Kingdom
The NHS (Health and Social Care in Northern Ireland) does not pay for private treatment you choose abroad, and your EHIC or GHIC does not cover planned treatment. Standard travel insurance does not normally cover you if you travelled for elective surgery: you may need specialist cover. If you are on an NHS weight-management programme or a waiting list, discuss your plans with your GP before you decide, and agree how your aftercare will be provided once you are home (NHS).
The NHS is not liable for negligence or failure of treatment abroad, and the Foreign Office cannot usually help: planned treatment is treated as a commercial arrangement. Plan your aftercare and how records will be shared before you go.
🇮🇪 If you live in Ireland
The HSE Cross Border Directive scheme only refunds planned care in another EU or EEA country that is publicly funded in Ireland, with a referral, up to what it would cost in the Irish public system; travel and accommodation are not refunded. So cosmetic treatments, hair transplants and laser eye surgery, which are not publicly funded in Ireland, are outside it. Your EHIC does not cover planned treatment in another EU country (EU): it is for care that becomes necessary during a stay. Hospital care with a night in hospital may need the HSE's approval before you go (EU).
Ask your GP before you go how follow-up would work once you are home, and check whether your travel insurance covers planned treatment and its complications: many policies exclude it.
🇫🇷 If you live in France
Purely aesthetic procedures and their follow-up are not reimbursed by the Assurance Maladie, in France or abroad. Other planned care in another EU country is refunded only if it is reimbursable in France, and at most at the French rate: care without a night in hospital, such as most dental care, needs no prior authorisation; send the paid invoices with form S3125 to your CPAM. Weight-loss surgery can be offered in France after preparation with a specialised team: ask your doctor whether you qualify before paying abroad. Care with at least one night in hospital (a sleeve, for example; a purely cosmetic operation is never refunded) needs your CPAM's prior authorisation (form S2) before the trip, and the French eligibility criteria, to be refunded (EU).
Ask your CPAM (health insurance office) and your mutuelle (top-up insurer) before you go how care for a complication would be covered once you are home, and check your travel insurance.
🇺🇸 If you live in the United States
Check whether your health plan covers anything abroad: most do not cover planned treatment, and Original Medicare generally does not pay for care outside the United States, with limited exceptions. Consider supplemental cover, including medical evacuation.
Seek care promptly if a complication develops, during travel or after you return, and bring your overseas records in English. Legal recourse abroad may be more limited than in the United States.
🇦🇺 If you live in Australia
Medicare doesn't cover you when you're overseas, reciprocal health care agreements only cover some situations, and basic travel insurance rarely covers medical tourism: get a specialised policy for your procedure, its complications and medical evacuation, and tell your insurers everything. Ask your private health fund whether it pays anything for complications of surgery done overseas, and about waiting periods for treatment at home.
You, your family or your insurer pay for further care or an evacuation. Consular staff can contact your family and give lists of English-speaking hospitals and lawyers, but cannot pay bills or recommend surgeons. Smartraveller advises taking someone with you.
🇳🇿 If you live in New Zealand
Make sure your travel insurance covers complications and medical evacuation, and talk to your health practitioner in New Zealand about the procedure and its risks before you go. ACC does not pay for treatment costs overseas: ask ACC before you go what it would cover if you are injured by the treatment and need care once you are home.
Get copies of your surgical details before you leave: problems can appear once you are home, and your practitioner in New Zealand will need them. Check with a health practitioner before flying after surgery.
🇸🇦 If you live in Saudi Arabia
The Ministry of Health sends patients abroad at its expense only by royal order or on the decision of the High Medical Commission. Planned treatment you choose yourself, such as cosmetic surgery, is private and at your own cost.
Ministry-referred patients are followed by the Saudi health attaché in the country of treatment. If you go privately, nobody follows you: get supplemental insurance that includes medical evacuation before you go (CDC), and ask what it pays for treating a complication, talk to your doctor in Saudi Arabia before you leave, and if a problem starts once you are home, see a doctor at once and bring your records.
🇩🇪 If you live in Germany
Statutory insurance (GKV) can refund planned care from a provider in another EU or EEA country or Switzerland, at most what it would pay in Germany and only for care it covers; hospital treatment needs your fund's approval first (§13 SGB V). Cosmetic surgery is not covered. Private insurance (PKV) depends on your policy: ask before you book. For weight-loss, dental or eye treatment, tell your fund and your doctor at home about any complication. The cost-sharing rule for cosmetic surgery (§52(2) SGB V) is about operations that were not medically needed.
Check your travel insurance for complications, and agree with your doctor at home who will see you afterwards.
🇨🇦 If you live in Canada
Provincial and territorial health plans rarely cover any of the cost of care outside Canada, and then usually only a small part (Government of Canada). In Ontario, OHIP pays for planned treatment abroad only with written prior approval from the Ministry of Health before the treatment, applied for by your doctor, and only if the procedure is not available in Ontario (or a delay would be life-threatening or cause serious irreversible harm); travel, accommodation and meals are never covered. Other provinces have their own rules: ask your plan before you book. Rules differ by province (Ontario's prior-approval rule is above): check your own plan's out-of-country rules, for example BC's MSP, Quebec's RAMQ or Alberta's AHCIP, before you book.
Buy travel medical insurance that covers the treatment's complications and transport home: Ontario encourages it even when the treatment has prior approval. Foreign hospitals can be very expensive and may ask for cash in advance (Government of Canada).
🇳🇴 If you live in Norway
For care received in another EEA country, Norway refunds only care you would have had cover for in Norway, at most what it would have cost the public system there; hospital treatment follows separate rules and may need prior approval.
Talk to your doctor or dentist in Norway before you go, keep every invoice and record, and check your travel insurance for complications. If the care is something folketrygden covers and you had it in the EEA, apply to HELFO within the time limit.
🇸🇪 If you live in Sweden
For planned dental care in the EU or EEA, Försäkringskassan can refund what you would have received for necessary dental care in Sweden, afterwards; cosmetic dental work is not refunded, and you can ask for an advance decision (förhandsbesked) on the amount. For other planned care you can apply in advance; you pay travel and lodging yourself (1177).
Agree with your region or health centre (vårdcentral) how the follow-up works once you are home, keep every record, and check your travel insurance for complications.
🇧🇪 If you live in Belgium
For planned care in another EU or EEA country you are refunded at most what the Belgian insurance would pay, and only for care it covers in Belgium; care with a night in hospital or very specialised care usually needs your mutualité's prior authorisation (INAMI; EU). Travel and accommodation are yours to pay (EU).
Talk to your doctor or dentist in Belgium before you go, ask your mutualité in writing what it would refund, keep every invoice and record, and check your travel insurance for complications.
🇳🇱 If you live in the Netherlands
Your basic insurance refunds care abroad only if the same care is insured in the Netherlands, up to the usual Dutch rate; ask your insurer beforehand, as it can set conditions such as a referral (Zorginstituut Nederland). For adults the basic insurance covers surgical dental care, X-rays and removable dentures; implants only in special cases (Rijksoverheid).
Talk to your GP (huisarts) or dentist before you go, ask your insurer in writing what it would refund, keep every invoice and record, and check your travel insurance for complications.
🇸🇬 If you live in Singapore
MediShield Life is designed for subsidised bills at public hospitals in Singapore and does not cover treatment overseas; MediSave can be used for elective hospitalisation and day surgery abroad only at accredited hospitals (Ministry of Health, 2024).
Ask your Integrated Shield Plan insurer in writing what it covers abroad, agree the follow-up with a doctor in Singapore before you go, keep every record, and get insurance that covers complications.
🇦🇪 If you live in the United Arab Emirates
What your UAE health insurance pays for planned treatment abroad depends on your plan: ask your insurer in writing before you book, and get insurance that covers complications and transport home.
Agree with a doctor or dentist in the UAE who will see you once you are back, keep every record and invoice, and check what your insurer pays for treating a complication of care done abroad.
🇩🇰 If you live in Denmark
For care bought in another EU or EEA country you can get the subsidy you would have had in Denmark, never more than you paid; planned hospital treatment with at least one night in hospital needs your region's prior approval (Styrelsen for Patientsikkerhed). You pay first and claim afterwards.
Talk to your doctor or dentist in Denmark before you go, ask your region's patient office what it would pay, keep every invoice and record, and check your travel insurance for complications.
🇦🇹 If you live in Austria
For planned care in another EU or EEA country you are refunded only for care you are entitled to under Austrian law: outpatient care at 80% of the Austrian contract tariff (the Wahlarzt rule), never more than you paid; hospital treatment needs your insurer's approval first (oesterreich.gv.at).
Talk to your doctor or dentist in Austria before you go, ask your health insurer in writing what it would refund, keep every invoice and record, and check your travel insurance for complications.
🇫🇮 If you live in Finland
Kela can refund treatment in another EU or EEA country if it is medically necessary and part of the services of the Finnish public system, at most what it would have cost in your wellbeing services county; you pay first, claim within 6 months of paying, and can ask Kela well in advance how much it would refund (Kela).
Talk to your doctor or dentist in Finland before you go, ask Kela for advance information, keep every invoice and record, and check your travel insurance for complications.
🇨🇭 If you live in Switzerland
Basic insurance covers treatment in Switzerland and emergencies abroad, not planned treatment abroad: the exception is a treatment not available in Switzerland, when your doctor applies to the insurer's medical adviser first (FOPH). Supplementary insurance may cover more: ask it in writing. Switzerland is outside the EU: the EU cross-border refund rules do not apply to Swiss residents, wherever the clinic is.
Agree the follow-up with a doctor or dentist in Switzerland before you go, ask your insurer in writing what it covers, keep every record, and get insurance that covers complications.

Questions patients ask
How do I check a surgeon or a clinic in Croatia?
Use Croatia's official registers: Croatian Medical Chamber: register of doctors (Imenik liječnika); Croatian Institute of Public Health (HZJZ): National Register of Healthcare Providers. Ask the doctor for their first name, surname and Medical Chamber membership number. Search the Croatian Medical Chamber's register of active members by first name and surname, or by the full membership number (Članski broj).
How long should I stay in Croatia after weight-loss surgery?
Plan at least 10 days before you fly home. The CDC advises not flying for 10 days after chest or abdominal surgery. One trip, but a long one: at least 10 days before flying home, then two years of specialist follow-up you must arrange at home before you go. If you use a CPAP machine for sleep apnoea, contact the airline well before the flight about medical equipment, carry the machine in your hand luggage (not in the hold), and ask your sleep team for a letter about it (NHS).
Is it safe to get weight-loss surgery in Croatia?
We do not rate countries or clinics: what matters most is the clinic and the surgeon. Check both in the official registers, ask the clinic the questions on this page, and walk away at a red flag, for example: no questions about your BMI, health conditions or eating history before a date is offered. This is not medical advice: talk to your own doctor before you book.
