A fever in a hotel room, a fall on uneven pavement, or chest pain after a long flight can turn a stay in Athens stressful very quickly. Knowing when should travellers go to hospital helps you act early, avoid unnecessary delay and choose the right level of care when you are away from home.
The simplest rule is this: go to hospital or call emergency services when symptoms could be life-threatening, rapidly worsening, or require equipment and specialists that a clinic cannot provide. For urgent but stable problems, a private doctor can often assess you quickly, arrange tests and treatment, and tell you clearly whether hospital care is needed.
When should travellers go to hospital immediately?
Do not wait for a routine appointment, a pharmacy visit or a hotel doctor if there is a real possibility of a medical emergency. Call 112 or 166 in Greece, or go to the nearest emergency department, if you or someone you are travelling with has any of the following warning signs:
- Chest pressure, chest pain, severe shortness of breath, blue lips, sudden collapse or an irregular heartbeat with dizziness
- Signs of stroke, including facial weakness, one-sided arm or leg weakness, new confusion, difficulty speaking, sudden vision loss or an abrupt severe headache
- Unconsciousness, a seizure lasting more than five minutes, or a seizure followed by difficulty waking or breathing
- Heavy bleeding that will not stop with firm pressure, vomiting blood, coughing blood, or black, tar-like stools
- A serious head injury, especially after loss of consciousness, repeated vomiting, confusion, worsening headache or use of blood-thinning medication
- Severe allergic reaction, such as swelling of the lips, tongue or throat, wheezing, widespread hives with breathing difficulty, or fainting
- Severe abdominal pain with a rigid abdomen, persistent vomiting, fainting or pregnancy-related pain or bleeding
- A major injury, suspected broken neck or back, open fracture, severe burn, deep wound, or inability to safely move a limb
These symptoms do not always mean the worst outcome, but they need emergency assessment. Travelling can make it tempting to minimise symptoms, particularly when you have a flight, tour or meeting planned. That is a risky trade-off when time-sensitive treatment may matter.
Do not drive yourself if you are unstable
If there is severe pain, fainting, breathing difficulty, neurological symptoms or major bleeding, use an ambulance where possible. Do not ask an unwell person to walk down hotel stairs, take public transport or sit in a taxi without support. Keep any medicines, allergy details, passport and insurance information nearby, but do not delay emergency help to find paperwork.
Same-day medical care is often the right first step
Not every urgent illness requires a hospital. Many common travel problems need prompt attention but can be assessed safely outside an emergency department when the person is alert, breathing comfortably and generally stable.
Seek same-day medical care for a high fever that persists or is accompanied by dehydration, a painful ear or throat infection, urinary symptoms, diarrhoea that is not settling, a spreading rash, a painful cough, migraine, back pain, or a minor injury that may need an X-ray. You should also be assessed promptly after an animal bite, a cut that may need stitches, a tick bite, a needlestick injury, or a possible sexually transmitted infection.
The same applies if you have run out of essential medication, lost a prescription, or are concerned that a new medicine is causing side effects. A clinician can review the situation, issue an appropriate prescription where clinically suitable and explain what needs monitoring.
For many travellers, the challenge is not deciding whether they feel ill. It is deciding whether they are ill enough for hospital. A same-day consultation gives you a practical middle route: an English-speaking doctor can examine you, check vital signs, arrange diagnostic testing and escalate you to a private hospital if the findings call for it.
Symptoms that need extra caution while travelling
Some symptoms deserve a lower threshold for urgent assessment because flights, heat, unfamiliar food, alcohol, long walking days and disrupted routines can complicate a health condition.
Breathlessness or leg swelling after a flight
Long periods of sitting can increase the risk of a blood clot, especially if you have recently had surgery, are pregnant, take oestrogen-containing medication, have a history of clots or have cancer. One-sided calf pain or swelling, unexplained breathlessness, chest pain, coughing blood or fainting after travel needs urgent assessment. Sudden breathlessness or chest pain is an emergency.
Heat illness and dehydration
Athens can be very hot, particularly in summer. Headache, thirst, cramps, nausea and dark urine may improve with rest, cooling and fluids if symptoms are mild. However, confusion, fainting, seizures, very hot skin, persistent vomiting or inability to drink can indicate severe heat illness and requires hospital care.
Children, older adults and people with heart, kidney or diabetes-related conditions can deteriorate faster. Do not assume exhaustion after sightseeing is harmless if the person seems unusually drowsy, confused or weak.
Stomach illness that is not improving
Traveller’s diarrhoea is common, but dehydration is the concern. Arrange same-day care if vomiting or diarrhoea is frequent, lasts beyond a day or two, includes fever or blood, or prevents you from keeping fluids down. Go to hospital if there is severe weakness, confusion, fainting, severe abdominal pain or signs of significant dehydration such as very little urine.
Existing conditions that suddenly change
If you live with asthma, diabetes, epilepsy, heart disease or severe allergies, have a plan before symptoms become severe. An asthma attack not responding to your usual reliever inhaler, very high or low blood glucose with symptoms, repeated seizures, or suspected anaphylaxis requires emergency care. Bring your usual medication and a brief medical summary when you travel, but seek help early if your usual plan is not working.
How to decide between a clinic, hospital or telemedicine
A useful question is not simply, “How bad is this?” Ask, “Could this become dangerous in the next few hours, and do I need hospital equipment now?” If the answer might be yes, choose hospital assessment.
A clinic is often suitable when symptoms are uncomfortable or concerning but stable, such as infection symptoms, a minor injury, a rash, medication needs or moderate gastrointestinal illness. The benefit is fast evaluation without waiting in an emergency department. If examination, blood tests, imaging or observation suggests a more serious cause, the clinician can arrange a safe transfer or direct referral.
Telemedicine can be useful for early advice, prescription questions, mild symptoms and deciding what to do next. It is not appropriate for red-flag symptoms, because a video call cannot replace emergency examination, oxygen monitoring, scans or immediate treatment.
In Athens, HOMED Clinic provides walk-in consultations, hotel and home visits, telemedicine, diagnostic testing, prescriptions and coordination with private hospitals. This can be particularly helpful when you are stable but too unwell to navigate an unfamiliar healthcare system alone.
What to do while help is arranged
Keep the person resting in a safe position and do not give food or drink to someone who is drowsy, confused, vomiting heavily or may need urgent surgery. For suspected stroke, note the time symptoms started or when the person was last seen well. For allergic reactions, use a prescribed adrenaline auto-injector immediately if indicated, then call emergency services.
For a possible fracture or serious injury, avoid moving the affected area unnecessarily. Apply firm pressure to active bleeding with a clean cloth. If you are managing mild dehydration while waiting for medical advice, take small, frequent sips of water or an oral rehydration solution rather than large amounts at once.
If you are staying at a hotel, tell reception that you need medical assistance and ask them to help emergency services reach your room. If you are in a holiday flat, make sure the building entrance is accessible and keep your mobile phone charged.
FAQs
Should I go to hospital for a fever while travelling?
A fever alone does not always require hospital care. Seek same-day assessment if it is high, persistent, accompanied by severe pain, rash, dehydration, breathing symptoms or worsening weakness. Go to hospital urgently for confusion, stiff neck, severe breathlessness, collapse or signs of sepsis such as extreme shivering and marked deterioration.
Can I wait until I return home for treatment?
Only if symptoms are mild, improving and you can drink, move and function normally. Do not delay assessment for worsening pain, fever, breathing problems, dehydration, infection signs, injury or any symptom that could make flying unsafe.
What if I am unsure whether it is an emergency?
When in doubt, choose prompt medical assessment. It is far better to be told that your condition can be treated as an outpatient than to miss the early signs of a serious illness. Clear advice, fast examination and a plan for the next few hours can make the rest of your trip safer and far less stressful.
