out isn't simple. Although
asthma is usually thought of as
a childhood affliction, close to 60
percent of asthmatics are adults.
Although the disease's severity
varies from person to person,
asthmatics share a chronic dis-
ease that has no cure — not yet.
Tragically, almost 4,000 peo-
ple in this country die each year
from this disease. Many under-
estimate it as mere wheezing or
as a minor, temporary ailment.
Thankfully, however, advances
in asthma management have
made it possible to reduce the
severity and frequency of symp-
toms so that more people are
better able to manage the dis-
ease.

WHAT HAPPENS IN THE
ASTHMATIC LUNG
Asthma is a chronic lung dis-
ease, often described as a reac-
tive airway disease, with varying
levels of obstruction. Recent re-
search shows that inflammation
of the lining of the bronchi, the
large air passages to the lungs,
is the most common symptom of
asthma. This causes the airway
lining to swell and narrows the
airway opening. Sometimes, the
inflammation and swelling can
last for weeks following an
episode. Most asthmatics have
some degree of inflammation all
of the time.
The unpleasant sensation of
not being able to breathe occurs
when someone with asthma is
exposed to a stimulus known as
a "trigger," such as pollen, mold,
viral infections or cold weather.
The bronchi of people with asth-
ma are so sensitive to one or
more of these stimuli that when
they're exposed, they experience
an asthma attack.
Air enters the lungs through
the trachea, which branches
into the right and left bronchi.

he word asthma is derived
from a Greek word meaning
"to breathe hard" or "gasping."
To understand what it feels like
to be an asthmatic, imagine
tightness in your chest and
wheezing when you breathe.
You can pull some air into your
lungs, but you can't fully expel
it.
Or, breathe in very deeply,
hold for a second, and then try to
take another breath. You can't.
Now add to that coughing and a
feeling of panic because you're
suffocating during an asthma
attack!

Those passages, in turn, are
subdivided into smaller and
smaller bronchial tubes and
bronchioles, which finally end
in air sacs called alveoli. In the
alveoli, inhaled oxygen enters
the bloodstream and carbon
dioxide is removed to be ex-
haled.
During an asthma attack, the
muscles that line the airways
tighten, constricting the route
through which air goes in and
out. The lining of the bronchial
tubes swells and becomes in-
flamed, blocking the passage of
air even more. The mucus that
usually lubricates the airways
becomes thick and sticky and
may plug up the airways. It be-
comes harder and harder to
breathe out because air deplet-
ed of oxygen is trapped in the
