Am I fit to go on a cruise? What to check before you sail
Physician-led pre-cruise checks · fit-to-travel documentation where clinically appropriate
Cancer Immunology Researcher
No website can tell you whether you are fit to sail — that is a clinical judgement, and cruise lines themselves require a doctor's confirmation in defined situations. What this page can do: show you the situations where the lines require clearance, the situations where a pre-cruise consultation is genuinely worth your time, and a structured way to put your health questions to a Mobi Doctor physician — who can assess you online and issue fit-to-travel documentation where clinically appropriate.
If you are unwell right now, this page is not for emergencies — call 112 (EU) or your local emergency number.
Cruise lines require a doctor's confirmation for these
- Pregnancy: most major lines will not carry passengers who will have entered the 24th week of pregnancy by the end of the voyage, and require a fit-to-travel letter at earlier stages. Check your line's exact cut-off — it is in the ticket terms.
- Very young infants: typically no infants under 6 months (12 months on transatlantic, transpacific and remote itineraries).
- Supplemental oxygen or dialysis: carriage is possible on many ships but must be arranged and medically confirmed in advance through the line's special-needs process.
- Recent major events: after recent surgery, a heart attack, a stroke or a hospital admission, most lines' terms require medical fitness confirmation — and their check-in health questionnaires ask directly.
Worth a doctor's review before you book or board
- Heart, lung or kidney conditions — stability at sea, medication timing across time zones, and what the ship's medical centre can and cannot do for your condition.
- Insulin-treated diabetes — dose timing on itineraries that cross time zones, storage on board and ashore, and hypo planning on excursion days.
- Immunosuppression — ships concentrate thousands of people; norovirus and respiratory infections circulate. Timing, precautions and a response plan are worth agreeing with a doctor first.
- A history of blood clots — cruise holidays usually bracket long flights; the combination deserves a prevention plan.
- Severe seasickness history — effective prescription options exist, including patches that must be started before sailing; a doctor can advise what suits your health and other medicines.
- Complex medication regimens — supplies, storage, customs rules at ports of call, and what to do if a dose is missed or lost.
- Reduced mobility — cabin, tender and excursion practicalities are the line's department, but the physical demands of an itinerary are worth an honest medical conversation.
Every passenger, every sailing
- Medicines: bring your full course plus at least a week spare, in original packaging, in hand luggage — with a written medication list. Ships cannot reliably replace prescriptions at sea.
- Insurance: confirm your travel insurance covers cruising specifically, including medical evacuation — onboard medical care is private and charged, and evacuation from sea is expensive.
- Vaccinations: routine vaccinations current, plus destination-specific requirements for your ports of call.
- Hand hygiene: soap and water before meals beats sanitiser alone against norovirus — use the wash stations at buffet entrances, every time.
- Port days: heat, sun and unfamiliar food are the shore-side risks — check the live conditions for your ports the morning you dock.
Put your questions to a doctor before you sail
Same-day video appointments · EU-licensed physicians · the fixed consultation fee is shown before you confirm — nothing is charged on this page.
Answer a few questions about your trip and your health — in your own words. We attach your answers to your consultation so the physician starts with the full picture; nothing here is assessed by software, and nothing is shared until you book.

Sailing within the next two weeks? Book promptly — fit-to-travel letters are usually dated close to departure, and lines set documentation deadlines.
Frequently asked questions
Can I go on a cruise while pregnant?
Usually yes in earlier pregnancy, but every major line sets a hard limit: if you will have entered the 24th week by the end of the voyage, they will not carry you, and before that most require a doctor's fit-to-travel letter stating your due date and fitness to sail. A Mobi Doctor physician can assess you online and provide the letter where clinically appropriate.
Can I cruise if I use oxygen or have dialysis?
Often yes — many ships accommodate supplemental oxygen and some itineraries support dialysis arrangements — but it must be arranged in advance through the cruise line's special-needs process with medical confirmation. Start early: the paperwork typically needs to be complete weeks before sailing.
Does travel insurance cover me on a cruise?
Only if it says so. Standard travel policies often exclude or limit cruising — check for a specific cruise clause, cover for onboard (private, charged) medical treatment, and medical evacuation at sea. The ship's medical centre is not part of any national health system, including the EHIC/GHIC arrangements.
