ACUTE MOUNTAIN SICKNESS (AMS):
Altitude sickness, also called Acute Mountain Sickness (AMS) generally occurs above 2,500 meters, but serious altitude sickness is rarely occurs below 3,000 meters. Symptoms range from suffering a mild headache and weariness to a life-threatening situation, where fluid in the lungs (HAPE) or brain (HACE) is built-up. AMS is caused by the body having difficulty adapting to the lower oxygen levels at higher altitudes. Usually this is exacerbated by ascending too quickly but could also be due to individual sensitivities. As AMS can be fatal, it is important to know about the disease, its symptoms, how to prevent them and how to treat AMS.
