A common question that many new climbers ask is ‘what is altitude sickness?’
Altitude sickness is the side effect caused by exposure to high altitudes. As a person reaches higher altitudes, the air contains less oxygen which begins to negatively affect the human body.
Symptoms usually develop from around 2,500 meters of altitude.
Extreme cases can include fluid build up in the brain characterized by loss of coordination, confusion, inability to walk and even coma. If left untreated, AMS can be lethal.
