📋Overview
This condition occurs when the bronchial tubes become irritated and swollen, frequently leading to a cough that produces thickened mucus. The inflammation is generally categorized as either acute, often developing from a respiratory infection, or chronic, which involves persistent irritation of the airways.
Acute cases typically improve within a few weeks, while the chronic form is characterized by a productive cough lasting for at least three months over two consecutive years. This long-term version is considered a type of chronic obstructive pulmonary disease and often results from prolonged exposure to inhaled irritants.
