The train from Porto to Coimbra takes about an hour and ten minutes, and I spent the first twenty minutes of it doing nothing but breathing — deliberately, the way you do when a flare has started somewhere behind your ribs and you need it to hold off until you’re horizontal again. Outside the window, terraced vineyards slid past in the low autumn light. Inside, I was doing the quiet arithmetic that anyone with a chronic illness learns to do on the move: how far to the next stop, where the nearest pharmacy might be, whether I’d packed enough of the right things in my carry-on rather than the bag now stowed two seats away.
This is the part travel writing rarely mentions — not because it’s unspeakable, but because it doesn’t photograph well. Yet for the millions of people travelling with conditions like Crohn’s, POTS, rheumatoid arthritis, chronic fatigue syndrome, migraine disorders, or autoimmune disease, this arithmetic is the actual trip planning. Get it right and the world opens up in the same way it does for anyone else — maybe more, because you’ve had practice paying attention. Get it wrong and a good destination turns into a bad week.
This isn’t a piece about whether you can travel with a chronic illness. You can, and this is how.
Start With Medication Logistics, Not Destination Dreaming
The single most consequential decision you’ll make happens before you book anything: how you’re carrying and documenting your medication. Airlines and border agents don’t care how sick you are — they care whether your paperwork matches your pills.
Carry a letter from your prescribing doctor, on letterhead, listing every medication by generic name, dosage, and the condition it treats. Get it in English even if you’re travelling somewhere else, and if you’re heading to a country where English isn’t widely used at pharmacies or clinics — much of rural Japan, for instance, or inland Morocco — get a second copy translated. Keep this letter with your medication at all times, not filed away in a folder in your main luggage.
Split your supply. Half your medication goes in your carry-on, half in checked luggage (if you’re checking anything at all — many chronic illness travellers avoid checked bags entirely for this reason). Pack for double the length of your trip where possible; flight delays, border closures, and lost luggage are common enough that “just enough” is a risk you don’t need to take.
Liquids, injectables, and controlled substances each have their own rules depending on the country. The U.S. Transportation Security Administration and the UK’s NHS travel advice for long-term conditions both publish current guidance, but the practical move is to call ahead — the airline’s disability or medical assistance desk, not the general helpline — at least two weeks before departure.
Choosing Destinations That Work With Your Body, Not Against It
Some places are simply easier to be chronically ill in, and it has nothing to do with how “developed” they are. It’s about density of medical infrastructure, climate stability, and how forgiving the terrain and transport are if you need to slow down mid-day.
Portugal is a genuinely good example. Coastal towns like Cascais or Ericeira have compact centres, mild year-round climates, and pharmacies (farmácias, marked by a green cross) on nearly every corner stocked with EU-standard medication, often available without prescription for things you might run out of. If you’re drawn to a longer, unhurried stay, Portugal’s slow travel regions beyond Lisbon are worth a look precisely because they don’t demand a packed itinerary to feel worthwhile.
Japan, similarly, rewards chronic illness travellers with reliable trains that run on a schedule you can plan a flare around, spotless public restrooms everywhere, and konbini stores (7-Eleven, Lawson, FamilyMart) stocked with electrolyte drinks, heat patches, and basic pain relief at 3am if you need it.
By contrast, destinations that demand long overland transits with unpredictable timing — parts of Central America, some of the more remote stretches of South America covered in honest bus travel guides — are not off-limits, but they require more buffer and more contingency planning than a flare-prone traveller might want on a first attempt.
| Consideration | Easier destinations | Harder destinations | Why it matters |
|---|---|---|---|
| Pharmacy access | Portugal, Japan, South Korea | Rural Nepal, remote Patagonia | Running out mid-trip is the most common crisis |
| Transport reliability | Japan (trains), Netherlands (rail) | Long-distance buses in Central America | Flares often need a fixed, predictable rest point |
| Climate stability | Coastal Portugal, temperate Europe | High-altitude Andes, tropical monsoon regions | Heat, cold, and altitude all provoke symptoms |
| Medical English | Most of Western Europe, South Korea | Rural Morocco, rural Ethiopia | Explaining a rare condition under stress is hard enough in your own language |
| Rest infrastructure | Slow travel hubs, smaller towns | Fast-paced multi-city tours | Chronic illness needs built-in downtime, not squeezed-in downtime |
Build the Itinerary Around Rest, Not Sights
The instinct with a bucket list destination is to pack it — five cities in ten days, a museum every morning, a hike every afternoon. That itinerary will break you if your body runs on a limited daily budget of energy, and it will also mean you experience very little of any single place.
The alternative is to plan like a slow traveller by necessity rather than preference. Pick one base — a neighbourhood, not a city-hopping route — and stay long enough to learn its rhythms: which café opens early enough for a slow breakfast, which pharmacy the pharmacist speaks decent English at, which park bench catches morning shade instead of full sun. Cities built for this kind of unhurried pace — several of which turn up in guides to Europe’s best cities for slow travel — tend to have the density of amenities that make low-energy days survivable rather than wasted.
Build every day around a single anchor activity, with the rest of the day left deliberately loose. In Lisbon, that might mean one museum — the Museu Nacional do Azulejo, quiet and rarely crowded — with the afternoon left open for a nap, a slow tram ride, or simply sitting in Jardim da Estrela. The goal isn’t to see less. It’s to see what you see properly, without paying for it in a crashed afternoon or a lost following day.
Travel Insurance: Read the Pre-Existing Condition Clause Twice
Standard travel insurance policies routinely exclude pre-existing conditions unless you disclose them explicitly and pay for a rider. This is the single most expensive mistake chronic illness travellers make — not because insurance is unaffordable, but because the wrong policy gives you a false sense of cover.
When you call an insurer, use the exact medical terminology from your diagnosis, not a simplified version. “Ulcerative colitis” and “IBS” are not interchangeable to an underwriter, and a claim can be denied over exactly this kind of imprecision. Ask directly: does this policy cover a flare of my specific diagnosed condition, and does it cover emergency evacuation if I need treatment beyond what the local hospital can provide?
The UK government’s Foreign, Commonwealth & Development Office travel advice publishes country-specific healthcare quality notes that are worth reading before buying a policy, not after — some destinations will require a higher-tier evacuation policy regardless of your condition, simply because the nearest adequate hospital is a flight away.
Airports, Airlines, and the Art of Asking for Help Early
Every major airline has a medical assistance or special assistance desk, separate from general customer service, and it’s worth calling this line directly rather than relying on the online booking form. Requesting a wheelchair or early boarding, even if you don’t use mobility aids regularly, can mean the difference between a manageable travel day and a flare triggered by an hour of standing in a security queue.
TSA Cares in the US, and equivalent assistance schemes at airports like Amsterdam Schiphol or Seoul Incheon, allow you to request a private screening if you’re carrying medical devices, insulin pumps, or ostomy supplies that you’d rather not explain in a public line. Book this at least 72 hours ahead where possible.
On long-haul flights, an aisle seat near the bathroom is worth the extra fee if your condition involves gut issues or frequent urination — this is not a luxury upgrade, it’s risk management. Compression socks for anyone with circulatory or clotting concerns aren’t optional either; ask your doctor before a flight longer than four hours.
Food, Water, and the Reality of Eating While Chronically Ill Abroad
Dietary restrictions compound quickly when you’re managing a chronic illness and trying to eat safely in an unfamiliar food culture. Southeast Asian markets, for instance, are extraordinary for fresh, affordable food, but navigating them with dietary limits takes a bit more homework — the same care that applies generally to eating at local markets in Southeast Asia applies doubly if you’re managing a gut condition, food sensitivities, or need to avoid cross-contamination.
Learn the key phrases for your specific restriction in the local language before you go — not just “no gluten” but the actual words for wheat, soy, shellfish, or whatever triggers you specifically, written on a card you can hand to a server. In much of Europe, this is straightforward; in more rural regions of Asia, Africa, or Latin America, it can take real effort, and it’s worth building slack into your schedule for the meals that don’t work out.
When to Slow Down Mid-Trip — and How to Actually Do It
The hardest skill in chronic illness travel isn’t logistics. It’s permission — giving yourself the actual permission to cancel the afternoon you’d planned because your body has said no today.
Build a one-day buffer into every four or five days of itinerary, unscheduled and unbooked. If you don’t need it, it becomes a lazy morning at a café. If you do need it, it’s the difference between a manageable flare and a ruined week. This is standard practice among people who travel with chronic pain or fatigue conditions, and it’s the same principle that makes destinations built for slower travel — smaller regional bases rather than big-city circuits — genuinely better suited to unpredictable bodies.
The Bottom Line
- Medication logistics come first: split your supply between carry-on and checked bags, carry a doctor’s letter with generic drug names, and call the airline’s medical assistance desk directly rather than relying on general booking forms.
- Choose destinations for pharmacy density, transport reliability, and climate stability — not just for the sights. Portugal, Japan, and South Korea tend to be easier bases than places demanding long, unpredictable overland transit.
- Buy travel insurance that explicitly names your condition, using precise medical terminology, and confirm evacuation cover before you fly.
- Build unscheduled buffer days into every itinerary — roughly one for every four or five active days — and treat them as necessary infrastructure, not wasted time.
- Base yourself in one place longer than feels ambitious. A slower, single-neighbourhood trip will show you more of a place than a packed multi-city itinerary you’re too depleted to actually enjoy.
