Chronic
Bronchitis
WHAT IS CHRONIC
BRONCHITIS?
Bronchitis is the inflammation of
the lining of the bronchial tubes. When the bronchi are
inflamed and/or infected, less air is able to flow to
and from the lungs and a heavy mucus or phlegm is
coughed up. Many people suffer a brief attack of acute
bronchitis with cough and mucus production when they
have severe colds. Acute bronchitis is usually not
associated with fever.
Chronic
bronchitis is defined by the presence of a
mucus-producing cough most days of the month, three
months of a year for two successive years without other
underlying disease to explain the cough. This
inflammation eventually leads to scarring of the lining
of the bronchial tubes. Once the bronchial tubes have
been irritated over a long period of time, excessive
mucus is produced constantly, the lining of the
bronchial tubes becomes thickened, an irritating cough
develops, and air flow may be hampered, the lungs become
scarred. The bronchial tubes then make an ideal breeding
place for infections.
Chronic
bronchitis may precede or accompany pulmonary
emphysema. These two conditions together are
commonly referred to as Chronic Obstructive Pulmonary
Disease (COPD).
WHAT CAUSES CHRONIC
BRONCHITIS?
Cigarette smoking is by far the
most common cause of chronic bronchitis. The bronchial
tubes of people with chronic bronchitis may also have
been irritated initially by bacterial or viral
infections.
People
exposed to industrial dusts and fumes in the workplace,
such as coal miners, grain handlers, and metal molders,
are also at high risk of developing this disease.
In fact, a recent study found that the fraction of COPD
attributed to work was estimated as 19.2% overall and
31.1% among never smokers.
Air
pollution can worsen chronic bronchitis symptoms when
atmospheric concentrations of sulfur dioxide and other
air pollutants increase. These symptoms are intensified
when individuals also smoke.
HOW SERIOUS IS
CHRONIC BRONCHITIS?
Over 9.1 million Americans
are diagnosed with chronic bronchitis by a health
professional annually. Chronic bronchitis affects people
of all ages, but is higher in those over 45 years old.
Females are more than twice as likely to be diagnosed
with chronic bronchitis as men. In 2002, 2.9
million males were diagnosed with chronic bronchitis
compared to 6.2 million females.
Together
with emphysema and other chronic lower respiratory
diseases, excluding asthma, chronic obstructive
pulmonary disease (COPD) is the fourth leading cause of
death in the U.S, claiming the lives of more than
120,000 Americans.
Chronic
bronchitis is often neglected by individuals until it is
in an advanced state, because people mistakenly believe
that the disease is not life-threatening. By the time a
patient goes to his or her doctor the lungs have
frequently been seriously injured. Then the patient may
be in danger of developing serious respiratory problems
or heart failure.
HOW CHRONIC BRONCHITIS
ATTACKS
Chronic bronchitis doesn't strike
suddenly. After a winter cold seems cured, an individual
may continue to cough and produce large amounts of mucus
for several weeks. Since people who get chronic
bronchitis are often smokers, the cough is usually
dismissed as only "smoker's
cough."
As time goes
on, colds become more damaging. Coughing and bringing up
phlegm last longer after each cold.
Without
realizing it, one begins to take this coughing and mucus
production as a matter of course. Soon they are present
all the time, before colds, during colds, after colds,
all year round. Generally, the cough is worse in the
morning and in damp, cold weather. An ounce or more of
yellow mucus may be coughed up each
day.
TREATMENT FOR CHRONIC
BRONCHITIS
The treatment of chronic bronchitis is
primarily aimed at reducing irritation in the bronchial
tubes. The discovery of antibiotic drugs has been
helpful in treating acute bacterial infection associated
with chronic bronchitis. However people with chronic
bronchitis do not need to take antibiotics
continually.
Bronchodilator drugs may be
prescribed to help relax and open up air passages in the
lungs, if there is a tendency for these to close up.
These drugs may be inhaled as aerosol sprays or taken as
pills. Some physicians believe that inhaled
corticosteroids are useful.
To
effectively control chronic bronchitis, it is necessary
to eliminate sources of irritation and infection in the
nose, throat, mouth, sinuses, and bronchial tubes. This
means an individual must avoid polluted air and dusty
working conditions and give up smoking. Your local
American Lung Association can suggest methods to help
you quit smoking.
If the
person with chronic bronchitis is exposed to dust and
fumes at work, the doctor may suggest changing the work
environment. All persons with chronic bronchitis must
develop and follow a plan for a healthy lifestyle.
Improving one's general health also increases the body's
resistance to infections.
WHAT SHOULD YOU DO IF YOU HAVE
CHRONIC BRONCHITIS?
A good health plan for any
person with chronic bronchitis should include these
rules: See your doctor or follow your doctor's
instructions at the beginning of any cold or respiratory
infection.
-
Don't
smoke! Contact your local American Lung Association at
1-800-LUNG-USA (1-800-586-4872) for information on how
to quit smoking.
-
Follow a
nutritious, well-balanced diet, and maintain your
ideal body weight.
-
Get
regular exercise daily, without tiring yourself too
much.
-
Ask your
doctor about getting vaccinated against influenza and
pneumococcal pneumonia.
-
Avoid
exposure to colds and influenza at home or in public,
and avoid respiratory irritants such as secondhand
smoke, dust, and other air
pollutants. |
