Medical Treatment Abroad: When Travelling to Switzerland Is Not the Answer

Medical treatment abroad: start with the reasons not to go

Medical treatment abroad is common. Residents of Great Britain made an estimated 523,000 visits abroad for medical treatment in 2024, 196,000 of them to Turkey and 64,000 to Poland, according to the Office for National Statistics, which publishes the figures as official statistics in development. Switzerland is not among the ten most visited countries.

This guide covers the other side of the decision: the situations in which travelling for treatment, including to Switzerland, is the wrong choice. We are a concierge team that matches patients with clinics in our network, and when treatment at home is the better answer, we say so. The reasons below are the ones that public health bodies and the research literature return to.

Emergencies are never a case for travel

A condition that cannot wait is treated where the patient is. The NHS describes 999 as the number for life-threatening emergencies like serious road traffic accidents, strokes and heart attacks, and other countries have their own emergency numbers. Any arrangement that begins with a booking and a flight is, by definition, not an emergency pathway.

The same holds while a trip is being planned. A symptom that worsens is a reason to be seen locally now, not a reason to bring the trip forward.

When the same care is available at home

For a straightforward condition with an established treatment, the case for travelling rests on waiting time, preference or price rather than on medicine. The NHS draws the same line for its own money: under the S2 route it funds planned state treatment in an EU country or Switzerland only with prior approval, only when the treatment is routinely available on the NHS in the patient's circumstances, and only when there would be an undue delay at home. Travel and accommodation are not included.

Nor does travelling guarantee speed. At equal medical urgency, University Hospital Zurich gives priority to patients with Swiss social insurance from Zurich and from the cantons that have given the hospital a service mandate. Travelling for price is a weak case in Switzerland: the same hospital charges self-payers who live abroad a base rate of CHF 16,200, against the CHF 11,405 to CHF 11,420 that the canton of Zurich lists for 2026 for a patient with Swiss basic insurance, as our guide to the cost of treatment in Switzerland explains.

A specialist's view does not require a trip. Hirslanden International, for example, asks for the medical reports and has the chosen doctor give an opinion on the case before anything is booked. If that opinion confirms the plan your own doctors have made, the plan can go ahead at home.

Conditions that need close follow-up

Treatment does not end at discharge, and follow-up is a known weak point of medical travel. In a survey of 17,543 members of a large German sickness fund who had received treatment in other EU or EEA countries, information exchange between providers across borders was rare and largely carried out by the patients themselves, and 12 per cent of those prescribed medicines abroad reported problems.

Some treatments are built on years of aftercare. Weight-loss surgery needs specialist long-term support with lifelong annual reviews, according to the UK's National Travel Health Network and Centre, whose factsheet also warns that follow-up care might not be easily available and may not be covered by the NHS. Dentists in the UK have reported concerns about the lack of continuity of care after commercial dental treatment abroad, the same factsheet notes. A chronic disease that needs regular adjustment, or treatment spread over many months, raises the same question: who sees you after the trip, and with which records.

If the honest answer is that nobody at home will, the treatment is in the wrong place. A Swiss opinion on paper, with treatment and follow-up by a team near where you live, can be the better arrangement.

When travel itself is the risk

Flying after surgery carries a risk of its own. The UK Foreign Office warns that air travel after major surgery increases the risk of a blood clot, which can be life-threatening, and the CDC Yellow Book advises that medical tourists should not fly for 10 days after chest or abdominal surgery. NHS guidance on cosmetic surgery abroad recommends not flying for 5 to 7 days after breast surgery or liposuction and 7 to 10 days after facial procedures or a tummy tuck.

Whether a particular patient is fit to fly after the procedure is a medical judgement that TravelHealthPro says should be made by the traveller's doctor or dentist. For a frail patient, or anyone whose condition could deteriorate in the air, the trip itself can outweigh the benefit of a marginally better treatment setting. The practical side of travel, companions and the flight home is covered in our guide to visas for medical treatment in Switzerland.

Unproven treatments and the pull of hope

Some trips are driven by treatments that are not established anywhere. A systematic review of medical tourism in the Journal of Travel Medicine found that stem cell therapies are often not well researched and offer minimal evidence of efficacy, yet draw patients through anecdotal advertisements and a last sense of hope. The CDC warns that cancer patients who travel for such treatment risk harm from complications or from forgoing or delaying approved therapies.

A Swiss address does not turn an experimental treatment into an established one. If the main attraction of a clinic is a result no one at home will promise, that is the signal to stop and ask your specialist why. What is permitted in Switzerland and which indications have evidence behind them is set out in our guide to stem cell therapy.

How safe medical tourism is: what the evidence shows

The evidence is thinner and more lopsided than the question deserves. Most published data describe complications seen after patients return home, which counts failures but not successes. A 2026 rapid review in BMJ Open found 655 patients treated in NHS hospitals between 2006 and 2024 for complications of elective surgery abroad, 385 after weight-loss surgery and 265 after cosmetic surgery, and no studies reporting benefits. It put the cost to the NHS at £1,058 to £19,549 per patient in 2024 prices, on very low certainty evidence.

Across studies the pattern is consistent. A 2023 systematic review in the Annals of Plastic Surgery identified 589 patients with complications after cosmetic surgery abroad; infection was the most common, and 81 per cent of the bacterial organisms were mycobacteria. A review of 214 patients treated in the United States found complications that were mainly infectious (50.9 per cent) and often needed more than two months of treatment, with 36.8 per cent admitted to hospital and 51.8 per cent needing surgery. The Journal of Travel Medicine review reports complication rates as high as 56 per cent in the studies it covered.

The public bodies' warnings are not tied to particular destinations. Among medical tourists the most common complications are infection-related, according to the CDC, and the UK Foreign Office notes that there have been complications and deaths abroad from medical procedures. At one London hospital, 96 per cent of the surgical patients who presented with complications of cosmetic surgery over 17 months had been operated on abroad (Whiteman and colleagues, 2025), and a 2022 audit by the British Association of Aesthetic Plastic Surgeons counted 324 patients who needed surgery after returning to the UK in four years, with the annual number up 44 per cent in 2021.

Insurance gaps: what travel insurance and the EHIC do not cover

The cost of what follows a complication can be larger than the price of the operation. The NHS warns that most travel insurance policies will not cover planned treatment abroad, and the UK Foreign Office that standard travel insurance does not normally cover people who travelled abroad for elective surgery. The EHIC and GHIC cover necessary care during a visit, not planned treatment.

Switzerland adds a gap of its own: people who stay in the country solely to receive treatment cannot take out Swiss health insurance. Hospitals such as University Hospital Zurich ask for a cost guarantee or a deposit before admission and require an additional payment when the costs exceed it. TravelHealthPro's advice is inclusive medical insurance that covers all potential complications, including medical evacuation home, arranged before travel.

If complications appear after you are home, the bill may fall on you. When things go wrong abroad, patients may have little option other than arranging further treatment at their own expense, TravelHealthPro notes, and a British embassy or consulate cannot pay medical bills or pay for a return to the UK.

If something goes wrong: records, complaints and legal recourse

Records are the first protection. The CDC advises medical tourists to request copies of their overseas medical records in English and to give them to every clinician they see afterwards, and TravelHealthPro adds x-rays and scans, collected before departure. Tell every clinician at home about the treatment abroad: infectious disease specialists writing in Clinical Infectious Diseases note that patients may not volunteer it and that special infection control measures may be warranted. What Swiss law says about access to your own medical records is covered in our note on patient confidentiality in Switzerland.

Recourse from home is limited. The UK Foreign Office treats planned medical treatment as a commercial arrangement and cannot usually help with problems over the care received or its cost, and the NHS is not liable for negligence or failure of treatment abroad. A legal analysis in the AMA Journal of Ethics describes several barriers that make it difficult for patients harmed abroad to recover damages.

In Switzerland two practical safeguards exist. Every doctor practising in the country must be recorded in the federal MedReg register, which shows diplomas, specialist titles and cantonal licences, so a licence can be checked before booking. A patient who suspects a treatment error that caused harm, and who has not been able to settle the case directly with the liability insurer of the doctor or hospital, can apply to the out-of-court expert opinion service of the Swiss Medical Association (FMH). Under its regulation, as of 1 August 2024, the patient pays a fee of CHF 300, plus CHF 700 if an opinion is organised, both plus VAT, and the cost of the opinion is paid by the liability insurers. The opinion is not binding, and hospitals and practices organised as legal entities take part only with their consent.

A decision checklist before you book

Work through these points before paying anything. One that does not hold is a reason to pause; several are a reason to be treated at home.

If they all hold and there is still a reason to come, write to us and we can put the current options and published figures for the clinics in our network in front of you. If several do not, the better answer is at home, and we will say so.
