Altitude sickness, the mildest form being acute mountain sickness (AMS), is a harmful effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. [ 1 ] [ 2 ] [ 3 ] People's bodies can respond to high altitude in different ways.
Very high altitude = 3,500–5,500 metres (11,500–18,000 ft) Extreme altitude = above 5,500 metres (18,000 ft) Travel to each of these altitude regions can lead to medical problems, from the mild symptoms of acute mountain sickness to the potentially fatal high-altitude pulmonary edema and high-altitude cerebral edema .
The suggested rate of ascent is the same that applies to the prevention of acute mountain sickness and high-altitude cerebral edema. The Wilderness Medical Society (WMS) recommends that, above 3,000 metres (9,800 ft), climbers

Failure to acclimatize may result in altitude sickness, including high-altitude pulmonary edema or cerebral edema . [11] [12] Humans have survived for 2 years at 5,950 m (19,520 ft) [475 millibars (14.0 inHg; 6.89 psi) of atmospheric pressure], which appears to be near the limit of the permanently tolerable highest altitude.

This is a list of countries by risk of premature death from non-communicable disease such as cardiovascular disease, cancer, diabetes, or chronic respiratory disease between ages 30 and 70 as published by the World Health Organization in 2008. Measuring the risk of dying from target NCDs is important to assess the extent of burden from ...
Himalayas, on the southern rim of the Tibetan Plateau. Humans are generally adapted to lowland environments where oxygen is abundant. [12] At altitudes above 2,500 meters (8,200 ft), such humans experience altitude sickness, which is a type of hypoxia, a clinical syndrome of severe lack of oxygen.
[1] [2] Research at high altitude is also an important way to learn about sea level conditions that are caused or complicated by hypoxia such as chronic lung disease and sepsis. Patients with these conditions are very complex and usually suffer from several other diseases at the same time, so it is virtually impossible to work out which of ...
