Every year, at
least three trekkers suffer from AMS. High altitude sickness, often known as
altitude sickness, is the most serious medical risk while trekking in Nepal's
high Himalayas. The effect of altitude on people who ascend quickly to
elevations exceeding 2500 meters is known as high altitude sickness (8200ft).
The occurrence of AMS, generally known as Acute Mountain Sickness, is dependent
upon the elevation, the rate of ascent, and individual susceptibility. Many
people will experience mild symptoms of Acute Mountain Sickness during the
acclimatization process, and this is actually more common in fit young people
because they are more likely to try a fast climb by racing up the mountain like
some indestructible super hero!
Some people are
more vulnerable to altitude than others. If you know you get altitude sickness
easily, you just have to adjust your acclimatization schedule accordingly or
use preventive medicine (Diamox/Acetazolamide). Awareness of altitude sickness
has caused some trekkers to be unnecessarily anxious as they trek. As a general
rule, it is always recommended to walk gently for a safer and more enjoyable
trek and avoid high altitude sickness by planning a sensible itinerary that
allows for steady acclimatization to altitude as you climb up, but you could
run back down as fast as you like!
Our bodies have the ability to adjust to higher altitudes if given enough time. This process of adaption is called acclimatization. Altitude illness occurs as a result of a failure to adapt to a higher altitude. Fluid begins to leak from blood vessels, most often in the brain or in the lungs. If fluids collect in the lungs, you become breathless more easily while walking. A cough begins dry and irritative, but progresses to the production of pink, frothy sputum in its most severe form. The person ultimately drowns in this fluid if he/she doesn't go down. This symptom is referred to as high altitude pulmonary oedema (HAPE). When fluid leaks into the brain, you initially develop a headache, loss of appetite, nausea, and vomiting. This symptom is referred to as acute mountain sickness (AMS). If you become more tired, you like to lie down and do nothing, as you lose coordination and eventually sleep in a coma, and death is inevitable if you don't descend immediately. This syndrome is called HACE. HAPE and HACE can occur alone or in combinations.
These are the
main symptoms of AMS:
guidelines for the prevention of AMS:
there is no need to worry about high altitude sickness for a perfect trek, but
light activity during the day is better than sleeping because respiration
decreases during sleep, exacerbating the symptoms. Thank you!
