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. |
