Symptoms of Altitude sickness (AS)
Simple Altitude sickness (AS) is usually presented as the most minor problem due to altitude. The more severe problems are high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE).
The group of experts participating in the 7th International Hypoxia Symposium in 1991 in Canada,1 defined Altitude sickness (AS) as a syndrome occurring in the setting of a recent gain in altitude, consisting of headache and at least one of the following:
- gastrointestinal symptoms, such as anorexia, nausea or vomiting,
- fatigue or weakness, dizziness or lightheadedness, and
- difficulty sleeping.
Symptoms that may indicate life-threatening Altitude sickness (AS) include:
- HAPE
- persistent dry cough
- fever
- shortness of breath even when resting
- HACE
- headache that does not respond to analgesics
- unsteady gait
- increased vomiting
- gradual loss of consciousness.
