Asthmatics - don't suffer at altitude!
Copyright 2006 David Drinkall
Some kinds of exercise cause problems for asthmatics. Activities
like climbing and skiing have an additional problem. Not only
are there the exercise problems, but the altitude itself can
cause an additional challenge of its own.
It is possible that people with asthma are more likely to be
affected by altitude sickness. But what is altitude sickness?
And why should asthma sufferers be more likely to suffer from it?
Simply put, people who live at lower altitudes can become ill
when they visit high areas. They can feel light-headed, suffer
from headache, suffer from fatigue, insomnia and palpitations,
or experience lack of appetite, diarrhoea and abdominal pain.
One of the most acute collections of symptoms is around
breathing difficulties; liquid accumulates in the lungs.
Will altitude affect your asthma?
The conditions are high altitudes are often dry and cold, and
these conditions tend to worsen or trigger asthma. If your
asthma is triggered by cold conditions, you might find that high
altitudes are a problem, as the air temperature usually
decreases at higher altitudes.
Bear in mid, though, that fit, healthy people with
well-controlled asthma should have no problems coping with high
altitudes, provided that they go up slowly. Recognise and accept
your limitations. Make sure you have all your medicines with
you. You may need to adjust your dose, and to plan your intake
before, through and after your activity.
But be careful. In freezing conditions, pressurized inhalers may
not work properly. They should be warmed (e.g. in the hands)
before use.
Take it easy
Climbing and skiing can be very strenuous exercise and may
trigger exercise-induced asthma in some people.
Some kinds of asthma may be eased
If your asthma is triggered by house-dust mites, you may even
find that your asthma improves. Surprised? Why should this be?
Simply because the house-dust mite cannot survive at altitudes
higher than 'the snow line'.
Take time to acclimatize
People with asthma who fly directly into a place that is at high
altitude will not have time to acclimatize and may experience
problems. So talk to your doctor so that the altitude if you're
flying to a high-altitude destination several weeks before you
leave. This will allow you time to work out a personal asthma
action plan for the trip.
Your plan might involve increasing your preventer treatment for
several weeks before the trip to give the airways extra
protection. Or measuring peak flow while away to determine how
altitude is affecting your lung function. Or even simple things
like ensuring that you have enough medication and backup
medication.
Take care when exercising
Make sure you feel right at any particular altitude before going
higher. If you start feeling breathless, slow down. Drink plenty
of water, and eat small snacks often to prevent altitude
sickness. And, do tell your fellow climbers and skiers that
you're asthmatic.
Remember to take everything in stages, talk to your doctor and
keep your medicines to hand, and you should have a better time
this winter.
