Chronic bronchitis is a long-term respiratory condition in which the bronchial tubes are irritated and inflamed. Chronic bronchitis causes breathing problems that continue for long periods of time or recur regularly. The most common cause of bronchitis in the U.S. is smoking or second-hand smoke. Infections, allergies and asthma may also bring about or exacerbate chronic bronchitis.
Coughing
Individuals who suffer with chronic bronchitis experience coughing for long periods of time. The cough can last for months and may reoccur several times a year. The cough is often deep and may produce phlegm.
Shortness of Breath and Wheezing
Individuals may experience shortness of breath, wheezing and fatigue. These symptoms may become worse with physical activity. A doctor should be consulted for long-term wheezing or shortness of breath to rule out other conditions, such as asthma or emphysema.
Fever
Bronchitis inflames and weakens the bronchial tubes and lungs, making them more susceptible to infection. When this happens, a bronchitis sufferer may experience a fever. Antibiotics may be used to treat the infection and to relieve symptoms.
Pneumonia
In some individuals, chronic bronchitis may lead to pneumonia. This is more common in people with weakened immune systems and the elderly.
Lung Cancer
The chance of developing lung cancer increases for those who suffer from chronic bronchitis. Smokers with chronic bronchitis have an even higher risk of developing lung cancer.
