Altitude sickness, often known as Acute Mountain Sickness (AMS) is a particularly important medical consideration while trekking in Nepal. Altitude sickness means the effect of altitude on those who ascend too rapidly to elevations above 3000 meters. The initial symptoms of AMS are as follows:
These symptoms are to be taken very seriously. In case of an appearance of any of the above symptoms any further ascent should be avoided otherwise more serious, even life-threatening problems can happen. The only cure for Altitude Sickness is to descend to lower elevations immediately.
Acclimatization by ascending to no more than 300 to 500 meters per day above 3000 meters, and the proper amount of rest and dehydrations are the best methods for prevention of AMS.
