Chronic bronchitis is the inflammation, or irritation, of the airways in the lungs. Airways are the tubes in the lungs where air passes through. They are also known as bronchial tubes. When the airways are irritated, thick mucus forms inside of them. The mucus plugs up the airways and makes it hard for the person to get air into your lungs. Symptoms of chronic bronchitis include a cough that produces mucus (sometimes called sputum), breathing difficulties, and a feeling of tightness in the chest.


A physical examination will often show decreased intensity of breath sounds, wheeze (rales) and prolonged expiration. Most doctors depend on the presence of a persistent dry or wet cough as evidence of bronchitis. Pulmonary Function Tests (PFT) (or spirometry) must be performed in all patients affected with chronic cough. An FEV1/FVC ratio below 0.7 that is not fully reversible after bronchodilator therapy shows the presence of COPD, that requires more aggressive therapy and brings with it a more severe prognosis than simple chronic bronchitis. A chest X-ray that shows hyperinflation; collapse and consolidation of lung areas would support a diagnosis of pneumonia. Some conditions that look like bronchitis may be indicated by chest radiography. A blood test could indicate some sort of inflammation, as indicated by a raised white blood cell count and elevated C-reactive protein. Further obstruction to the airways is the result of more goblet cells in the small airways. This is generally typical of chronic bronchitis Although infection is not the reason or cause of chronic bronchitis it is seen to help in sustaining the bronchitis.

For acute worsening of chronic bronchitis, if antibiotics are used a meta-analysis found that "amoxicillin/clavulanic acid, macrolides, second-generation or third-generation cephalosporins, and quinolones" may be more effective for treatment.
