Asthma is the intermittent inflammation and narrowing of bronchial
tubes, which provide the passageway for air movement. It may occur
in almost any age group ranging from infancy to old age. The main
distinction between asthma and emphysema or chronic bronchitis is
the reversibility. Asthma occurs episodically in the form of “attacks.”
In between these attacks, many patients experience no symptoms and
go about their business uninterrupted. Jackie Joyner, an Olympic
athlete, suffered from asthma, took medications on a regular basis,
and still competed in the Olympics in track and field. With effective
management of the disease, people can live relatively normal lives.

A variety of environmental exposures and other health problems
may trigger attacks. Many asthmatics suffer from severe symptoms
related to allergies. The various allergens capable of triggering
asthma attacks include dog, cat, and other animal hair, as well
as dust mites, weeds, grasses, molds, trees and even cockroaches.
Upper respiratory tract infections, acid indigestion and sinus infections
may also provoke asthma attacks in some people along with exercise
or physical exertion.
People suffering from asthma attacks usually complain of shortness
of breath, coughing and wheezing. The wheezing sounds like a high-pitched
noise similar to a flute and frequently worsens at night. The classic
dry cough of asthma intensifies during the night as well. |
