High Altitude sickness — also known as Acute Mountain Sickness (AMS), altitude illness, hypobaropathy, "the altitude bends", or soroche — is a pathological effect of high altitude on humans, caused by acute exposure to the low partial pressure of oxygen at high altitude. It commonly occurs above 2,400 meters (8,000 feet). It presents as a collection of nonspecific symptoms, acquired at high altitude or in low air pressure, resembling a case of "flu, carbon monoxide poisoning, or a hangover". It is hard to determine who will be affected by altitude sickness, as there are no specific factors that correlate with a susceptibility to altitude sickness. However, most people can ascend to 2,400 meters (8,000 ft) without difficulty.
Acute mountain sickness can progress to high altitude pulmonary edema (HAPE) or high altitude cerebral edema (HACE), which are potentially fatal. Altitude Sickness is a modification in a body on account of high height, a decrease in ecological weight makes breathing troublesome due to less oxygen. Dominantly, it happens above 3300m(10,000ft). This is the most perilous hazard that cripples the neglectfulness of trekkers. It is ensured that reliably more trekkers are lost of height illness.
