Asthma
What is
Asthma
Asthma
is a disease which affects the respiratory
system. The airways become narrowed, or blocked,
making breathing difficult.
The severity and frequency of attacks varies,
but generally, mild to moderate
Asthma
can be controlled with appropriate treatment.
In some cases, the symptoms can reverse, or
disappear altogether, without the need for any
medication.
Recognizing the Symptoms
An
Asthma
attack can last from a few minutes to a number
of hours, often occuring at night and during
humid weather conditions. It can be triggered by
physical activity, anxiety, stress, or a
reaction to an allergic or environmental agent
(allergen), such as smoke, pollen, or dust
mites.
The symptoms vary with age, but the usual signs
are breathing difficulty, particularly breathing
out
(emptying the lungs),
with a tight, dry-sounding cough, and occasional
wheezing
(a whistling noise from the chest).
As the attack worsens, breathing becomes more
labored, the chest feels very tight,
and the person experiences an uncomfortable
clammy feeling.
The attack can sometimes be relieved by rest,
moving to a cooler (not cold) less humid area,
or removing the allergic source until treatment
is available.
Any severe case of breathlessness, particularly
in the young and elderly, must receive urgent
medical attention.
