What causes bronchitis?
Bronchitis, a swelling of the airways in the lungs that causes coughing and mucus, can be either acute (short-term) or chronic (long-term).
Acute bronchitis is most often caused by a viral infection, such as a cold or flu. Bacteria can also sometimes cause acute bronchitis.
Chronic bronchitis is most often more common in smokers. However, nonsmokers can also get chronic bronchitis. You may be at higher risk of getting chronic bronchitis if you:
- Are older
- Have a family history of lung disease
- Had respiratory diseases in childhood
- Have been exposed to fumes or secondhand smoke
- Have gastroesophageal reflux disease (GERD)
