which condition is permanent inflammation of the airways accompanied by excess mucus production

Answer 1

The condition you are describing is chronic bronchitis, which is a form of chronic obstructive pulmonary disease (COPD). Chronic bronchitis is characterized by long-term inflammation of the bronchial tubes, leading to persistent cough, mucus production, and difficulty breathing. It is often caused by long-term exposure to irritants such as smoking, air pollution, or workplace hazards.
