When assessing a patient with asthma, which type of asthma is triggered predominantly by allergens?

The type of asthma that is primarily triggered by allergens is known as extrinsic asthma. This form of asthma occurs when the immune system overreacts to specific environmental triggers, such as pollen, dust mites, pet dander, or mold. In individuals with extrinsic asthma, these allergens provoke an inflammatory response in the airways, leading to symptoms such as wheezing, coughing, chest tightness, and shortness of breath.

Extrinsic asthma is often associated with a personal or family history of allergic conditions, such as hay fever or eczema, making the connection between allergens and the onset of asthma symptoms significant. Understanding this type of asthma is crucial for effective management, as avoiding allergens and implementing appropriate pharmacotherapy can help mitigate symptoms and reduce the frequency of asthma attacks.
