What is Altitude Sickness?
Altitude sickness, also known as acute mountain sickness (AMS), is a pathological effect of high altitude on humans, caused by acute exposure to low partial pressure of oxygen at high altitude. It commonly occurs above 8,000 feet (2,400 m). Symptoms usually develop between 6 and 24 hours after ascent and generally subside in 1–2 days, but they may persist for several days at high altitude.
1) What are the symptoms of altitude sickness?
The symptoms of altitude sickness may include headache, fatigue, loss of appetite, nausea, vomiting, dizziness, insomnia, and a feeling of drunkenness. In more severe cases, the individual may experience shortness of breath, coughing, chest tightness, and fluid build-up in the lungs.
2) Who is most likely to experience altitude sickness?
Altitude sickness can affect anyone, even those with good physical fitness. People who are most vulnerable to altitude sickness are those who ascend quickly, those who have had altitude sickness before, those with existing respiratory or cardiovascular issues, and those with a low iron level.
3) How can altitude sickness be prevented?
Altitude sickness can be prevented by ascending gradually, avoiding strenuous activity when first arriving at higher altitudes, drinking plenty of fluids, and avoiding alcohol. Taking acetazolamide and ibuprofen can help reduce the symptoms of altitude sickness.
4) How long does altitude sickness last?
The symptoms of altitude sickness typically last from 6-24 hours. In more severe cases, symptoms may persist for several days at high altitude.
5) Is altitude sickness fatal?
In most cases, altitude sickness is not fatal. However, in severe cases, it can lead to high-altitude cerebral edema (HACE), a life-threatening condition which requires immediate medical attention.
6) How can high-altitude cerebral edema (HACE) be treated?
High-altitude cerebral edema (HACE) is treated with oxygen therapy, descent to a lower altitude, and medications such as dexamethasone and nifedipine.
7) How can altitude sickness be treated?
The treatment of altitude sickness typically involves rest, avoiding strenuous activity, oxygen therapy, and medications such as acetazolamide and ibuprofen. Descent to a lower altitude can also help to relieve symptoms.
8) Can altitude sickness be prevented when flying?
Altitude sickness can be prevented when flying by avoiding alcohol and caffeine, drinking plenty of fluids, and avoiding strenuous activity. Taking acetazolamide can also help reduce the risk of altitude sickness.
9) Is there a difference between altitude sickness and mountain sickness?
Altitude sickness and mountain sickness are often used interchangeably to refer to the same condition. Mountain sickness is a general term that includes altitude sickness, high-altitude pulmonary edema (HAPE), and high-altitude cerebral edema (HACE).
10) Is there a cure for altitude sickness?
There is no cure for altitude sickness, however, the symptoms can be relieved with rest, oxygen therapy, medications, and descent to a lower altitude. Prevention is the best way to avoid altitude sickness.
