Altitude sickness

Overview

Altitude sickness (or high-altitude illness) includes acute mountain sickness, high-altitude pulmonary oedema, and high-altitude cerebral oedema. Acute mountain sickness typically occurs at altitudes greater than 2500 m (about 8000 feet), and is characterised by the development of some or all of the symptoms of headache, weakness, fatigue, listlessness, nausea, insomnia, and suppressed appetite. Symptoms may take days to develop or may occur within hours, depending on the rate of ascent and the altitude attained. More severe forms of altitude sickness have been identified.
