Published 26 October 2026 · IOC editorial team · General information, not an individual assessment.
For someone living in the UK, choosing gastric sleeve surgery abroad means choosing who will assess suitability, perform the operation and provide help after returning home. A country name alone cannot answer those questions. This guide compares decision points for Turkey, Spain and Portugal with the option of treatment in the UK; it does not rank countries by safety or promise a particular result.
Start with the option of care close to home
Discuss surgery and alternatives with your UK clinician before booking travel. Consider how easily you could attend appointments, obtain records and reach a bariatric team if problems develop. TravelHealthPro notes that bariatric surgery requires long-term support and reports the British Obesity and Metabolic Surgery Society's recommendation to have treatment in the UK, where access to follow-up can be easier. Read its guidance on travelling abroad for treatment alongside information from providers.
Turkey, Spain and Portugal: what actually differs?
The practical comparison is between named providers and written care plans. Do not infer that every hospital in one country offers the same care, staffing or emergency arrangements. The FCDO's Turkey health advice specifically warns that standards vary within countries as well as between them and advises independent research, rather than relying only on commercial information.
- Turkey: UK GHIC and EHIC cards are not valid. Check the named treatment provider against the Turkish Ministry of Health's approved-provider information, and establish separate cover and payment arrangements. A directory entry is not a guarantee of an individual outcome.
- Spain or Portugal: being in the EU does not make a private surgery package NHS-funded. The NHS S2 route has eligibility rules, requires advance authorisation and concerns eligible state-provided care, not an ordinary private package.
- UK: assess available NHS and private pathways with the relevant clinical service. Local care may simplify attendance, but suitability, funding and treatment timing still need individual confirmation.
Check the NHS S2 funding guidance and the arrangements relevant to where you live before making financial commitments. Do not assume a health card covers travel specifically for planned surgery.
Compare the full written quotation
Use the same questions for every quotation: who is operating, which hospital is named, what testing and anaesthesia are included, and what happens if the assessment finds surgery unsuitable? Request an itemised explanation of accommodation, transfers, medicines, follow-up and cancellation terms. Then ask separately about the cost of complications, readmission or an extended stay. A package label is not a substitute for these answers.
We have not published national average prices because unlike-for-like packages can create a misleading comparison. For IOC's current offer and exclusions, use the itemised Turkey gastric sleeve cost guide; compare another provider's dated quotation against the same items.
Make aftercare a booking condition
Ask for a written handover plan identifying the overseas team's responsibilities, the available contact channels and how in-person assessment will be arranged after you return. Clarify which follow-up is included, for how long, and what remains your responsibility. Remote messaging is not the same as local clinical examination or emergency care.
Agree how your operation report, discharge summary and follow-up plan will reach you and any clinicians involved in continuing care. Do not book on the assumption that a particular UK service has agreed to take over routine follow-up without discussing it first.
Insurance, recovery and return travel
Tell an insurer that the trip is for planned bariatric surgery and obtain written confirmation of what is and is not covered. Ask specifically about complications, additional accommodation and medical repatriation. Departure dates should depend on clinical advice and airline requirements, not only on a prepaid flight.
The NHS treatment-abroad checklist highlights second opinions, appropriate insurance, aftercare and extra travel costs. It also flags pressure to decide quickly and a lack of complication information as reasons to reconsider a booking.
Questions to send before paying a deposit
- Can I speak with the treating clinician and receive the named hospital and surgeon details in writing?
- How will you assess whether this operation is appropriate for me?
- What is the emergency and readmission pathway, and who pays for it?
- Who provides follow-up after I return, and what access is available in person?
- Can I receive the consent information and records in a language I understand?
- What happens to my booking if I need more time, a second opinion or a different treatment?
If Turkey remains an option after these checks, the gastric sleeve in Turkey guide explains IOC's pathway, eligibility discussion and recovery considerations. There is no need to choose a destination before understanding the treatment and the follow-up commitment.
