Chronic bronchitis is an inflammation of the bronchi, the main air passages in the lungs, which persists for a long period or repeatedly recurs.
The condition is characterized by excessive bronchial mucus and a productive cough that produces sputum for three months or more in at least two consecutive years, without any other disease that could account for this symptom.
