Acute Mountain Sickness (aka Altitude Sickness)Acute Mountain Sickness
Acute Mountain Sickness is a common and minor, though debilitating problem at high altitude. Rarely, it leads to two potentially fatal conditions - High Altitude Pulmonary and Cerebral Oedema (HAPE & HACE) - both of which are medical emergencies. In giving advice about travel to high altitudes it must be stressed that the simple adage of gaining height slowly and descending promptly if one is ill - advice known for generations in all high countries - cannot be bettered.
Most people feel at least a little unwell if they drive, fly or travel by train from sea level to 3500m. Headache, fatigue, undue breathlessness on exertion, the sensation of the heart beating forcibly, loss of appetite, nausea, vomiting, dizziness, difficulty sleeping and irregular breathing during sleep are the common complaints. These are symptoms of Acute Mountain Sickness (AMS), which usually develop during the first 36 hours at altitude and not immediately on arrival. Well over 50% of travellers develop some form of AMS at 3500m, but almost all do so if they ascend rapidly to 5000m (16,400ft).
Usually, these unpleasant effects of lack of oxygen wear off over two to three days, particularly if no further ascent is made. Once the body has acclimatised in this way, further gradual height gain is possible although symptoms may recur at any time. The question "How high, how fast?" has no absolute answer because of individual variation, but it is reasonable for healthy people of any age to travel rapidly to 3500m, though many will develop some degree of AMS after arrival. It is unwise to travel much above 3500m immediately from sea level.
Above 3500m, the speed of further height gain should be gradual and we advise no more than a 300m increase in sleeping altitude per day (with a rest day every third day) and spending at least a week above 3500m before sleeping at 5000m. This does not mean you can't ascend more than 300m in a day (eg. to cross a pass or attempt a summit), as long as you descend again before sleeping. The highest altitude where man lives permanently is about 5500m (18,000ft) but on mountaineering expeditions or a trek, residence for several weeks around 6000m (20,000ft) is quite possible and at these altitudes one should feel entirely well when acclimatised, being limited only by breathlessness on exertion.
There is unfortunately no way of predicting whom AMS will seriously trouble and who will escape it. It is tempting to suppose that being physically fit and avoiding smoking would help in prevention but unfortunately, this does not seem to be the case. Similarly, if you have previously been affected (or not), it seems no more or less likely that you will avoid AMS the next time you travel to altitude.
Strenuous exercise at altitude, whether or not the subject is fit, makes AMS worse; undue exertion and heavy loads should therefore be avoided until acclimatised. Patients with heart or lung disease or high blood pressure should seek specialist advice before travelling above 4000m.
