What is the likely cause of worsening symptoms during late summer to autumn?

• A. Tree pollen
• B. Grass pollen
• C. Ragweed
• D. Pine pollen

Answer: (C)

The worsening of asthma symptoms during late summer to autumn is most likely attributed to ragweed pollen. Ragweed is a common allergen that typically releases its pollen in late summer and continues through autumn. As the ragweed plant flourishes, its pollen can travel significant distances, exacerbating allergic reactions in individuals who are sensitive to it. This seasonal cycle can lead to increased inflammation of the airways in asthmatic patients, resulting in worsening symptoms. In contrast, tree pollen and grass pollen are more commonly associated with spring and early summer, making them less likely to be the primary cause of symptoms during late summer to autumn. Pine pollen, while potentially a trigger during its specific pollen season, is not typically associated with significant asthma exacerbations in the late summer to autumn timeframe when ragweed pollen peaks. Understanding these seasonal patterns is essential for effective asthma management and education.
