What to do about Altitude Sickness?
Altitude sickness can be prevented by acclimatization; that is a graduate rate of ascent (not more than 400-500 meters), allowing sufficient rest at various intermediate altitudes. The day air of the mountains tends to dehydrate you so an increased fluid intake is necessary. Try to drink at least four liters of water a day. On the trail, you can drink hot garlic soup that will help you to some extent. When we reach to our destination it is better to make some hiking up to a bit higher point and come down to the camp or hotel. This is a really good way to get acclimatization. You may take Diamox 250 mg tablets the night before flying/going to altitude. Sometimes the symptoms often disappear and the trek can be resumed.
