ASTHMA: DO YOU HAVE IT?

“When I would have an attack, it would feel like my chest
was in a vice”, recalls Steve Warshawer, elite ultra-marathoner, and sufferer
of exercise-induced asthma. Asthma

Warning Signs
So maybe you don’t even know you have asthma. That’s not uncommon. Asthma is defined, as
“chronic inflammation and constriction of the airways”, according to Dr.
Courtney Crim, director of the Respiratory Institute. Typical signs and symptoms include faster
breathing, wheezing and coughing, a feeling of tightness in the chest,
difficulty sleeping and a decrease in peak flow (the volume of air you can
expel from your lungs).
An asthma attack, however, is defined by symptoms including: difficulty speaking, increased heart rate, blue lips and, a peak flow reading that measures in the red zone and a lack of relief from your inhaler. If you don’t know if you have asthma, this would be mean continued wheezing and coughing, even after slowing down, or resting.
At
the Mayo Clinic, a correct diagnosis of asthma begins first with a thorough
physical exam, complete with a medical history, and a lung function test. A lung function test consists of both a
spirometer reading, used to measure the amount of air you can expel, and a peak
flow meter reading, used to measure the rate at which you can expel air from
your lungs. Your doctor might also give
you a bronchodilator to see if your lung function improves.
Should
your lung tests show that your lungs are performing below normal levels, your
doctor would need to rule out any other conditions that might cause these
results.
If you are diagnosed with asthma, your doctor will then
attempt to identify the type and class of your asthma. The types of asthma describe the conditions
that precipitate the symptoms and include: allergic, seasonal, exercise-induced,
nocturnal and non-allergic. The classes
describe the frequency of the symptoms and include: mild-intermittent,
mild-persistent, moderate-persistent and severe-persistent.
Much ground has been made in understanding the causes of
asthma. According to Dr. Courtney Crim, resident asthma expert and certified
pulmonologist at the Respiratory Institute, asthma results from an interaction
between the environment and genetics.
This
is particularly the case with both seasonal and exercise-induced asthma. Trees, grasses, flowering plants, pollen and
mold can trigger seasonal asthma. Trail
runners, especially need to be cautious of windy days when the dust or smoke
levels can trigger an attack. However,
in urban living—within 10 miles of heavily congested areas--second-hand smoke
and respiratory infections can also bring on both exercise-induced and seasonal
asthma.
Pull the Trigger
Luckily, most asthma triggers are avoidable, but much of
the asthma management depends on determining and removing them. Common triggers include:
The Respiratory Institute
suggests keeping a daily journal to help determine some of your triggers.
Asthma
treatment however, begins with medication.
Three types of medications are commonly prescribed for asthma:
fast-acting bronchodilators, long acting bronchodilators and inhaled
corticosteroids (ICS).
Both
ICS and long-acting bronchodilators are considered preventative, while
short-acting bronchodilators are considered to be quick-relief. While many runners with exercise-induced or
seasonal asthma rely solely on the quick-relief inhalers, most treatment plans
also involve a preventative treatment.
New
evidence suggests that if asthma is inadequately treated, it may get worse over
time and lead to a long term decrease in lung function and even permanent lung
damage.
If
asthma is treated properly, the quick-relief inhaler should only be used
periodically. Trail runners are often
prone to overuse of their inhalers, as they spend more time exposed to pollen,
dust and flowering plants than the average person. Ideally, runners should only use their inhaler
as a last resort, to prevent an attack.
And according to the Respiratory Institute, if you are using your
inhaler more than twice a week, your asthma symptoms may not be under control.
Runners
who are susceptible to exercise-induced asthma should avoid exercising when
pollen and dust levels are high or outdoors in the winter and should moderate
their exercise intensity. Those with
seasonal asthma may benefit by avoiding exercise when pollen levels are high, such
as in the spring, or when there is an increase in flowering plants.
Don’t let asthma keep you from enjoying the
trails this year. If you keep your
asthma symptoms under control, you can maintain your lung function and running
capacity. Again, if you are wheezing or
using your inhaler more than twice a week, see your physician immediately
because you could be at risk of permanent lung damage. And permanent lung damage can make that
wheezing while running permanent. As
runners, we know that breathing hard is part of the territory; not being able
to breathe, however, is unacceptable.

EXTRACTING ALTERNATIVES
Many asthma sufferers have found relief in the following
herbal extracts. These treatments are
not a replacement for asthma medication, and you should consult your doctor before
taking any of them:
