Which disease presents with dyspnea and wheezing?

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

Answer: (A)

Asthma is the classic disease that presents with both dyspnea and wheezing because it creates reversible airway obstruction from bronchospasm and airway inflammation. The airways become hyperresponsive and narrow in response to triggers (allergens, exercise, cold air, infections), producing wheeze as air moves through constricted passages and dyspnea from reduced airflow. This pattern often varies over time and responds to bronchodilators, making wheezing with shortness of breath a hallmark in many acute presentations.

Bronchitis can cause cough and sometimes wheeze, but its main feature is a productive cough from mucus production. COPD involves chronic, progressive dyspnea with a smoldering cough and sputum, not the classic episodic wheeze. Pneumonia typically presents with fever and localized chest findings like crackles or dullness, not primarily wheezing.
