Asthma
|
| Definition |
Asthma is a condition that involves
the lungs. Asthma may be active or inactive. When asthma is inactive
breathing is usually normal. When asthma is active it may cause
difficulties breathing. The breathing is difficult because the
airways become narrowed and may be blocked by secretions.
Inflammation of the airways may in part be responsible for causing
the narrowing and secretion build up described above.

| Causes |
Some people are born with asthma
and others may develop asthma later in life. The exact cause for
asthma is not known. Most people with asthma have triggering events
that activate their asthma. Several common things activate asthma
including infections, certain plant or animal material, dust,
exercise, and certain stresses.
|
| Treatment |
Asthma usually responds to
treatment. Medications that help relax the airways and decrease
inflammation are used to treat asthma. These medications may be
taken by inhalation or by mouth daily. When an asthma ia active
(often called an attack), other medications can also be given
intravenously. The best approach to a person with asthma is to
prevent an attack from happening or treat the asthma attack very
early on.

| Comments |
Most people with asthma maintain a
normal lifestyle and level of physical activity. However, asthma can
be dangerous if untreated. Some conditions, such as status
asthmaticus (severe asthma attack), can even cause death. This is
why it is important for anyone with asthma to work with their doctor
to make sure they have the proper medication. Also, if asthma
symptoms are not quickly controlled, the patient's doctor should
immediately be notified.
