Chronic bronchitis belongs to a larger family of medical conditions known as chronic obstructive pulmonary disease (COPD). The term COPD is given to any condition that causes difficulty in breathing as a result of constant blocking of the airways.
Bronchitis is identified by a cough, usually with some sputum production.The cough happens because the air tubes are permanently inflamed and secrete mucus. When cough and sputum have been present for more than 3 months in each of 2 consecutive years, the condition is called chronic bronchitis. In North America, about 1 person in 20 suffers from chronic bronchitis.
Smoking for many years causes about 90% of chronic bronchitis cases, and the great majority of people with chronic bronchitis are over 45 years of age. The risk of chronic bronchitis is also increased in workers employed in certain occupations such as coal mining, welding, asbestos work, or grain handling.
When breathing becomes more difficult for a person with chronic bronchitis, they may be experiencing an acute exacerbation of chronic bronchitis (AECB). During an acute exacerbation, breathing becomes more difficult because of further narrowing of the airways and secretion of large amounts of mucus that is often thicker than usual.
The further narrowing of airways in people with chronic bronchitis that results in AECB can be caused by allergens (e.g., pollens, wood or cigarette smoke, pollution), toxins (a variety of different chemicals), or acute viral or bacterial infections.
Bacterial infections are usually associated with mucus that turns a yellow or greenish colour and is typically much thicker than usual. Coloured mucus does not necessarily mean the person has a bacterial infection, however.
When a person has severe chronic lung disease from smoking, it may take something as minor as a chest cold to make their breathing so severe that they must be hospitalized.
AECB is associated with increased frequency and severity of coughing, and it is often accompanied by worsened chest congestion and discomfort. Increasing shortness of breath is also typical, and wheezing may be present as well.
People suffering from an acute exacerbation caused by infection may feel weak and have fever and chills. Doctors may recommend a chest X-ray to ensure that pneumonia is not the cause for these symptoms. Blood in the sputum may also indicate other medical conditions and should be reported to your physician promptly.
An acute exacerbation of chronic bronchitis (AECB) is said to have occurred if there has been an increase in frequency and severity of cough, along with larger amounts of sputum, or increasing shortness of breath.
The challenge lies in diagnosing the cause of an AECB so that the best treatment can be put in place. Therefore, it is important for the person with AECB to give their doctor a detailed description of the circumstances that may have led to the particular episode. For example, was there exposure to inhaled irritants such as secondhand smoke in the recent past? It is also important to describe any symptoms experienced to the doctor (e.g., fever, chills).
Your physician may investigate your AECB with a chest X-ray or a sputum culture. Treatment is often started before the test results confirm the condition.
Prevention of AECB for a person with chronic bronchitis includes:
Treatment of AECB may include:
Any person with chronic bronchitis should have a treatment or "care plan" in place for those times when an acute exacerbation suddenly hits. A doctor and patient must agree on which symptoms to watch for (e.g., shortness of breath, change in character or amount of mucus) before the person starts self-treatment. Such plans allow a person to start treatment right away so symptoms are kept as much under control as possible until a doctor can be seen.
*All medications have both common (generic) and brand names. The brand name is what a specific manufacturer calls the product (e.g., Tylenol®). The common name is the medical name for the medication (e.g., acetaminophen). A medication may have many brand names, but only one common name. This article lists medications by their common names.
