Acute Mountain Sickness (AMS)


Acute mountain sickness (AMS) is a condition that affects many travellers at high altitudes.  AMS is due to a decrease of oxygen and is especially common at altitudes above 2,500 m. The development of AMS is not dependent on gender or level of fitness. Acute mountain sickness (AMS) can be unpleasant and may reduce enjoyment of activities. In addition, if it is not managed appropriately, AMS can result in a more serious illness and in severe cases, can be fatal.
