Altitude Sickness Prevention

Altitude sickness, also known as acute mountain sickness (AMS), can occur when travelling to high-altitude destinations where oxygen levels are lower than at sea level. This commonly affects travellers visiting mountainous regions or destinations located at high elevations.

Altitude sickness can affect anyone, regardless of age or fitness level. The risk often increases when ascending too quickly without allowing the body enough time to adjust to changes in altitude.

Travellers may be at increased risk when visiting destinations such as the Himalayas, the Andes, high-altitude areas of Africa, or mountainous regions used for trekking, skiing or climbing activities.

Altitude sickness prevention may involve gradual ascent, staying hydrated, avoiding overexertion during early stages of travel and, in some cases, preventative medication where appropriate.

At Market Harborough Travel Clinic, our team can discuss your travel itinerary, planned altitude exposure and medical history to help provide personalised altitude sickness prevention advice for your trip.
