Alltitude Sickness – Causes and Symptoms of Altitude Sickness

Altitude sickness occurs at higher altitudes where you cannot get enough oxygen. This can occur in healthy adults who are around 2,500m above the sea level. About one out of two people may develop altitude sickness. It usually affects mountain climbers, skiers, travellers at high altitude or hikers. It can also happen to those people who go to high altitudes though they are not used to climbing high. Altitude sickness is also called as acute mountain sickness.

What causes Altitude sickness?

  • The main cause of Acute mountain sickness is the combination of decreased concentration of oxygen in the atmosphere and reduced air pressure.
  • In some cases fluid gets collected in the lungs.
  • Swelling of the brain also occurs.
  • These causes confusion, coma and if not treated immediately can cause death.
  • The faster you climb to a high altitude, the chance of getting altitude sickness increases.
  • Air at higher altitudes is thinner and as a result the body demands more oxygen.
  • When oxygen does not reach the cells, the person suffers from altitude sickness.
