altitude sickness
Elevation-induced illness
Altitude sickness is a condition caused by reduced oxygen at high elevations, typically above 8,000 feet.
Symptoms include headache, nausea, fatigue, and shortness of breath.
Severe cases can progress to life-threatening pulmonary or cerebral edema.
The remedy is descent to lower altitude.
Also called mountain sickness or acute mountain sickness (AMS).
