What is bronchitis?

Bronchitis is an inflammation of the bronchial tubes, or bronchi, that bring air into the lungs. Inflammation is a chemical reaction in the body that produces redness, swelling, and pain. The inflammation may be caused by a virus, bacteria, smoking or the inhalation of chemical pollutants or dust. In bronchitis, areas of the bronchial wall become inflamed and

swollen, and mucus increases. As a result, the air passageway is narrowed. Bacteria and viruses are usually present. Most cases of acute bronchitis disappear within a few days without lasting effects, although coughs may linger three weeks or more.

Bronchitis can either be of brief duration (acute) or have a long course (chronic). Acute bronchitis is usually caused by a viral infection, but can also be caused by a bacterial infection and can heal without complications. Chronic bronchitis is a sign of serious lung disease that may be slowed but cannot be cured. Anyone can get acute bronchitis, but infants, young children, and the elderly are more likely to get the disease because people in these age groups generally have weaker immune systems. Smokers and people with heart or other lung diseases are also at higher risk of developing acute bronchitis. Individuals exposed to chemical fumes or high levels of air pollution also have a greater chance of developing acute bronchitis. Chronic bronchitis is caused by inhaling bronchial irritants, especially cigarette smoke. Until recently, more men than women developed chronic bronchitis, but as the number of women who smoke has increased, so has their rate of chronic bronchitis. Because this disease progresses slowly, middle-aged and older people are more likely to be diagnosed with chronic bronchitis.
