High Altitude Medicine
High Altitude Cerebral Oedema (HACE)
The brain is affected by altitude because it needs a good supply of oxygen and may swell causing pressure. High Altitude Cerebral Oedema (HACE) is caused by brain swelling and can kill very quickly if not treated.
Some Common Symptoms of HACE:
- Headaches - very common at altitude, especially if you suffer headaches or migraine at home.
- Loss of balance - co-ordination and balance may be affected. Older people and those who are acclimatised feel less effect.
- Clumsiness’ and bad judgements increase the risk of accidents.
- Mood changes - on a ‘trip of a lifetime’ there will be good days and bad days. Bad days can trigger disappointment and depression. Be prepared for mood swings!
Before you go:
- Learn the signs of HACE & stroke.
- Prepare medical supplies.
- Consider expectations / fears and who will support you on bad days.
At altitude:
- Headache (AMS) avoid triggers - dehydration, exhaustion, alcohol - treat with painkillers.
- Stroke - treat with ½ a 300mg aspirin & descend. See a doctor.
- Be honest about how you feel.
Consequence if Ignored:
Loss of consciousness - confusion, drowsiness. Reduced breathing. DEATH. In serious cases death can occur within as little as an hour of symptoms being noticed.
