On Kilimanjaro climbing it is likely that more than 75% of climbers will experience at least some form of mild altitude sickness. This is caused by a failure of the body to adapt quickly enough to the reduced level of oxygen in the air at the increased altitude. This type of sickness is known as altoxia, a term which is used almost exclusively for Kilimanjaro, since this is the only commonly trekked mountain where these extreme altitudes are encountered so quickly.
Altoxia can have many different symptoms, the most common being headaches, light headedness, nausea, loss of appetite, vomiting and a mild swelling of the face, ankles and fingers. These symptoms can be rather unpleasant, can add a new and unnecessary dimension to the adversity faced by trekkers and can really take the shine off the experience. However, in this mild form altoxia does not generally have serious consequences and normally disappears within 48 hours The symptoms of altoxia should be largely if not completely relieved by the use of our ALTOX Personal Oxygen System.
