Travelling with a Chronic Health Condition

The question we hear most often from travellers who manage a chronic health condition is not 'will this be safe?' — it is 'will this be possible?' The answer, in the vast majority of cases, is yes. Our journeys are completed every year by travellers with well-managed diabetes, controlled heart conditions, asthma, arthritis, autoimmune conditions and a range of other diagnoses. The key word is managed: a stable, well-controlled condition travelling with a well-prepared traveller is a very different situation from an unstable one arriving without a plan.

What a chronic condition changes is not the journey itself but the preparation for it. The stakes of a missed dose, an unexpected flare or a supply problem are higher in rural Tanzania or on an expedition ship than at home, and the gap between 'my condition is fine' and 'my condition is fine for this specific journey in these specific environments' is one your own doctor, not a travel company, is best placed to close. Start that conversation early — ideally months before departure — and this article will help you know what to ask.

The pre-departure medical conversation

The most important step is also the most easily deferred: an honest, specific conversation with your prescribing specialist or GP about the journey you intend to take. Not 'is it okay to travel?' — a question that invites a vague reassurance — but 'here is the itinerary, here are the physical demands, here are the highest altitudes, here is the average daily walking, here is how remote the most isolated sections are. What do I need to prepare, and what would you want me to monitor?'

Bring the journey's physical grading, a copy of the itinerary, and any medical questionnaire our team has sent you. The answers that come back may be simple — a supply check, a dosage adjustment for altitude, a phone number for an emergency contact — or they may identify a genuine contraindication that should shape which journey or which module you choose. Either outcome is better reached at home with months to respond than in a remote location with nowhere to go.

Diabetes on a grand journey

Well-managed type 1 and type 2 diabetes are among the most common conditions our travellers manage, and most complete the journey without incident. The preparation is primarily logistical: insulin and certain injectables require a cold chain and a reliable supply, testing supplies need to be carried in sufficient quantity, and the physical demands of a walking day — which burns glucose faster than a desk day — need to be understood and built into dosing decisions.

Altitude adds a layer of complexity: at high elevation, blood sugar can behave differently, and the exertion of acclimatisation days can cause unexpected fluctuations. Your endocrinologist's input on how to monitor and adjust at altitude is worth having written down, not kept in memory. Carry a medical summary card that any healthcare provider anywhere can read — including the type, current medications, emergency contact and a note about hypoglycaemia symptoms — in a language accessible on your route.

Heart and cardiovascular conditions

Controlled high blood pressure, managed coronary artery disease and stable heart conditions do not preclude grand travel, but they require pre-departure clearance from a cardiologist for any journey that includes high altitude, significant physical exertion or remote sections far from medical facilities. High altitude in particular — the Peruvian Andes, the Bolivian altiplano, the Himalayas — increases cardiac workload in ways that are predictable and manageable for a healthy heart and that require explicit assessment for a compromised one.

Beyond the cardiologist sign-off, the practical preparation mirrors that for any serious medical condition: correct and complete medications, a doctor's letter, knowledge of the location of medical facilities along the route, and a clear agreement with your guide and tour manager about what to watch for and when to descend or seek help. Our pre-departure medical questionnaire exists to start exactly this conversation, and our guides carry pulse oximeters and oxygen on all high-altitude segments.

Respiratory conditions: asthma and COPD

Asthma is one of the most commonly managed conditions among our travellers, and in its well-controlled forms it is almost never a limiting factor. Carry more inhalers than you think you need — altitude, cold and dry air can all increase usage — and keep a rescue inhaler accessible rather than buried in a main bag. Know your triggers, and tell your guide what they are so they can give you early warning of environments that may challenge you: dusty tracks in Central Asia, smoky teahouse interiors, cold blasts on an Antarctic Zodiac.

Moderate or severe COPD requires a more careful assessment. The oxygen deficit at high altitude compounds the deficit caused by impaired lung function, and a journey that includes multiple days at above three thousand metres may not be suitable without formal respiratory assessment and, in some cases, supplemental oxygen. If your route includes significant altitude — and on Andes to Antarctica it inevitably does — discuss this specifically with your respiratory physician rather than relying on a general clearance.

Autoimmune conditions and immunosuppression

Travellers managing rheumatoid arthritis, lupus, Crohn's disease, multiple sclerosis and similar conditions are a regular and fully welcome part of our groups, and most of them travel very successfully. The considerations are largely those of any traveller with a significant medical history: supply, documentation, knowledge of the medical landscape on the route, and the specific question of whether the physical demands match the current state of the condition.

Immunosuppressant medications raise an additional layer of thought around vaccination: some live vaccines are contraindicated for people on certain immunosuppressant drugs, which makes a pre-departure appointment with a travel health clinic — attended with a full medication list — especially important. Infection risks vary by destination and are generally manageable with standard precautions; what changes is that the same infection may develop more seriously in an immunosuppressed person, which argues for prompt attention at the first sign of illness rather than a 'wait and see' approach.

Our medical questionnaire, and what happens with the answers

Every traveller joining a Viajes Globales journey completes a pre-departure medical questionnaire, and for travellers with a significant health history, this is not a formality. Our team reviews the responses, and where a condition or combination of conditions raises a question about safety, we come back to you — not to discourage travel, but to ensure that the right preparation is in place.

The guide on your departure is briefed on the medical composition of the group in broad terms, and knows where the nearest facilities of each type are located along the route. This knowledge has made a genuine difference more than once: a guide who already knows that two travellers are diabetic checks in differently on long summit days than one who does not. The questionnaire is the beginning of a conversation, not the end of one, and the more honestly you answer it, the more effectively we can look after you.
