Which statement about asthma inflammation is accurate?

1. Swelling of the airway occurs only when exposed to triggers

2. Narrowing of the airway occurs due to prolonged exposure to allergens

3. Bronchospasm does not contribute to inflammation in asthma

4. Inflammation can occur even without exposure to triggers

The correct answer is: Inflammation can occur even without exposure to triggers

The correct statement regarding asthma inflammation is that inflammation can occur even without exposure to triggers. This understanding is crucial because asthma is characterized by a chronic inflammatory process in the airways that can persist regardless of immediate environmental factors. In asthma, underlying inflammation can lead to airway hyperreactivity and increased sensitivity to various stimuli. This means that individuals may experience inflammation and associated symptoms even during periods of no identifiable triggers or external exposures. The fact that inflammation is a key feature of asthma highlights the importance of managing not just acute symptoms but also the ongoing inflammatory process. Additionally, recognizing that inflammation is not solely dependent on triggers informs treatment approaches that often include long-term control medications aimed at reducing airway inflammation, even in the absence of apparent exacerbating factors. This is vital for improving overall control of asthma and preventing future attacks.
