What is asthma exacerbation?

Asthma exacerbation refers to a sudden and significant worsening of asthma symptoms, which may require additional treatment or intervention. During an exacerbation, patients may experience increased shortness of breath, coughing, wheezing, and chest tightness. This can occur due to various triggers, including allergens, respiratory infections, or changes in weather. The intensity of the symptoms can vary, and in many cases, they may require bronchodilator use or even systemic corticosteroids to regain control of the condition. Recognizing and managing exacerbations promptly is vital in preventing further deterioration and maintaining optimal asthma control.

The other choices do not accurately describe asthma exacerbation; for instance, general malaise is more of a vague feeling of unease rather than a specific worsening of asthma symptoms, chronic asthma improving over time does not align with the concept of exacerbation, and brief periods of improved lung function contradict the notion of an exacerbation, which implies a decline in respiratory health.
