The condition of reversible narrowing of the airways during exercise causing increased breathing effort is called?

• A. Exercise-induced asthma
• B. Chronic fatigue syndrome
• C. Exercise-induced bronchitis
• D. Allergic rhinitis

Answer: (A)

When exercise triggers reversible narrowing of the airways, the condition is called exercise-induced asthma (often referred to as exercise-induced bronchoconstriction). During intense or prolonged activity, increased ventilation can dry and cool the airways, prompting airway smooth muscle constriction and the release of inflammatory mediators. This leads to breathing difficulty, wheeze, or coughing, but the narrowing is reversible with rest or appropriate treatment. Chronic fatigue syndrome is about persistent fatigue with various symptoms and is not about airway narrowing during exercise. Exercise-induced bronchitis isn’t a standard term for a reversible airway change, and bronchitis implies inflammation of the bronchi rather than a transient, exercise-triggered narrowing. Allergic rhinitis involves nasal symptoms and allergic inflammation of the upper airways, not the reversible lower airway constriction described here.
