Chronic bronchitis

Chronic bronchitis is a long-term inflammation of the bronchi, the airways that carry air to the lungs. It is characterized by a persistent cough that produces sputum for at least three months in two consecutive years, in the absence of other underlying lung diseases. This condition often results from prolonged exposure to irritants, such as cigarette smoke, and can lead to airway obstruction, impaired gas exchange, and increased susceptibility to respiratory infections. It is a major component of Chronic Obstructive Pulmonary Disease (COPD).
