Which condition is characterized by bronchoconstriction and excessive mucus production, often presenting with wheezing?

• A. COPD
• B. Asthma
• C. Pneumonia
• D. Croup

Answer: (B)

Airways tighten and mucus production increases when the lining of the airways becomes inflamed and hyperresponsive. This combination narrows the bronchioles and creates turbulent airflow that often produces a wheeze. That pattern is most characteristic of asthma, where triggers such as allergens, exercise, or cold air can provoke episodic bronchoconstriction and mucus plugging.

In COPD, symptoms are usually chronic and progressive, with a cough and excess mucus lasting over time and less emphasis on acute, episodic bronchoconstriction with wheeze. Pneumonia presents with infection signs—fever, productive cough, and crackles from alveolar consolidation—rather than primarily constricted airways. Croup involves upper airway swelling in children, producing a barky cough and often inspiratory stridor, not the classic wheeze from narrowed lower airways.

So the described presentation—bronchoconstriction with excessive mucus production and wheezing—most aligns with asthma.
