How does the body of an asthma patient typically respond to allergens?

In asthma patients, exposure to allergens triggers an exaggerated inflammatory response in the airways. This hyper-reactivity is a hallmark of asthma and leads to the release of inflammatory mediators such as histamines, leukotrienes, and cytokines. As a result, the airway becomes constricted and inflamed, causing symptoms such as wheezing, coughing, and difficulty breathing. This heightened inflammatory response is what distinguishes asthma from non-allergic reactions, where the body may have a more controlled or muted response.

The presence of allergens in an asthma patient's system leads to increased mucus production, airway swelling, and bronchoconstriction, which can significantly impede airflow. This process is an integral part of the asthma pathophysiology and helps explain why individuals with asthma are at a higher risk for severe respiratory symptoms when they encounter specific allergens, such as pollen, dust mites, or pet dander.
