High Altitude Sickness
Due to lack of oxygen, there are certain initial symptoms like headache, nausea, and vomiting which get reduced after acclimatization at that particular height. However, if the sickness persists or deteriorates, then the person should be sent to a lower altitude immediately.

According to experienced trekkers, at high altitudes, halts for acclimatization should be taken at every increase of 2000 to 4000 ft altitude. High altitude sickness can become fatal if it is not attended promptly and carefully. If ignored, serious problems of evacuation of the casualty may arise, and in the worst cases the person affected may die on the mountain.
