The height evil is an illness that can affect well the mountaineers, excursionists, skiers or before travelers who climb too rapidly to a mountain and generally it appears when the persons reach a big height, more than 3000 meters or sometimes only for traveling to cities placed in height (La Paz of Bolivia to 3650 meters, or City of Mexico to 2200 meters).

The symptoms of the evil of height are usually light:

• Migraine
• Insomnia
• Loss of the appetite

The presence of symptoms of evil of height is not equal in all the persons since only one of the 5 persons presents light symptoms to 2.000 and 3.000 m altitudes, but it is very strange that pulmonary edema (encharcamiento) appears and cerebral to these altitudes. On the other hand from 4.000 meters high most of the persons experience at least light symptoms, and some persons who remain to this altitude develop pulmonary or cerebral edema.
