Symptions

  •  headache
  • nausea and vomiting
  • dizziness
  • tiredness
  • loss of appetite shortness of breath
  • The symptoms are usually worse at night

The best way to prevent altitude sickness is to travel to altitudes above 3,000m slowly.It usually takes a few days for the body to get used to a change in altitude.You should also avoid flying directly to areas of high altitude,if possible take 2-3 days to get used to high altitudes before going above 3,000m avoid climbing more than 300-500m a day.you have to have rest day every 600-900m you go up, or every 3-4 days, make sure you’re drinking enough water, avoid alcohol, avoid strenuous exercise for the first 24 hours, eat a light but high calorie diet and avoid smoking

Symptoms of HACE:

  • headache
  •  weakness
  • nausea and vomiting
  •  loss of co-ordination
