Altitude Sickness While Traveling: Understanding and Managing High-Altitude Illness

Traveling to high-altitude destinations can be an unforgettable experience, but rapid exposure to altitude can lead to altitude sickness, also known as acute mountain sickness (AMS). This condition is common among travelers visiting mountainous regions and can affect anyone, even those in good physical health. This article explains what altitude sickness is, how to recognize symptoms, who is most at risk, and what to do if symptoms occur, helping you travel safely and confidently.

What is altitude sickness?

Altitude sickness occurs when the body has difficulty adapting to lower oxygen levels at higher elevations, typically above 2,500 meters (8,200 feet). Symptoms can appear within hours of arrival and may worsen if altitude continues to increase without proper acclimatization.

Altitude sickness ranges from mild to severe forms, and early recognition is essential to prevent complications.

Who is at risk of altitude sickness?

Anyone can develop altitude sickness, but certain factors increase the risk:

  • Rapid ascent to high altitude
  • Lack of acclimatization
  • Previous history of altitude sickness
  • Physical exertion soon after arrival
  • Dehydration
  • Travelers with heart or lung conditions

Note: Age and physical fitness do not protect against altitude sickness.

Common symptoms of altitude sickness

Symptoms may vary in intensity and often resemble flu-like discomfort. Common signs include:

  • Headache
  • Nausea or vomiting
  • Dizziness or lightheadedness
  • Fatigue or weakness
  • Shortness of breath on exertion
  • Sleep disturbances
  • Loss of appetite

Severe altitude-related conditions: when to act urgently

In rare cases, altitude sickness can progress to serious conditions requiring immediate medical care:

  • High-altitude cerebral edema (HACE): confusion, difficulty walking, altered consciousness.
  • High-altitude pulmonary edema (HAPE): shortness of breath at rest, chest tightness, cough, bluish lips.

These are medical emergencies and require urgent descent and medical attention.

What to do if you experience altitude sickness

  1. Stop ascending: Do not continue to higher altitude until symptoms improve.
  2. Rest and hydrate: Avoid physical exertion and drink fluids regularly.
  3. Descend if symptoms persist: Even a moderate descent can significantly improve symptoms.
  4. Seek medical advice: Consult a doctor to assess symptoms and determine next steps.

👉 Teleconsultation can be an effective first step to evaluate symptoms, receive medical guidance, and decide whether descent or in-person care is required.

Preventing altitude sickness while traveling

  • Ascend gradually and allow time for acclimatization.
  • Avoid intense physical activity during the first days.
  • Stay well hydrated.
  • Avoid alcohol and sedatives.
  • Sleep at a lower altitude when possible.
  • Seek medical advice before travel if you have chronic conditions.
