Altitude sickness after returning home

Rest at a lower altitude, drink according to thirst, avoid alcohol and strenuous exercise, and monitor whether headache, nausea, dizziness, fatigue, or poor sleep are settling.

Altitude sickness develops when the body has not adjusted adequately to reduced oxygen availability. Returning to a lower altitude removes that trigger, although a headache, tiredness, reduced appetite, or disturbed sleep may take time to fade.

Symptoms that begin only after arriving home may have another cause, including dehydration, a viral illness, migraine, medication effects, or exhaustion. The pattern, timing, breathing symptoms, and recent travel details help a clinician distinguish these possibilities.

Stay at low altitude and postpone another ascent until you feel fully well. Sleep, eat light meals if nausea limits appetite, and take fluids regularly without forcing excessive amounts. Avoid sedatives unless prescribed, because they can make breathing and alertness harder to assess.

For pain relief, check the label and ask a pharmacist whether a usual non-prescription medicine is suitable if you have kidney disease, stomach ulcers, take blood thinners, are pregnant, or use other medicines. Record whether symptoms are improving, unchanged, or worsening.

Seek emergency care for breathlessness at rest, chest tightness, blue or grey lips, confusion, unusual drowsiness, fainting, inability to walk steadily, coughing frothy or blood-stained fluid, or a severe worsening headache. Do not drive yourself if coordination or alertness is impaired.

Arrange prompt clinical advice when symptoms fail to improve after descent, keep returning, prevent normal drinking, or are difficult to separate from another illness. Tell the clinician where you travelled, how quickly you ascended and descended, and what medicines you used.

Ask whether your symptom pattern fits uncomplicated altitude sickness or warrants examination for a lung, heart, neurological, or infectious problem. Discuss when exercise and air travel are reasonable again, and how slowly to ascend on a future trip.

If you previously had marked symptoms, ask whether a personalised prevention plan or prescribed medicine is appropriate before returning to altitude.
