  • ADr. Anita Gupta, Anesthesiology, answered
    Allergic asthma is a common form of asthma that occurs when an allergen, such as pollen, pet dander, dust mites, or molds, is inhaled. These allergens trigger a hypersensitive response in the immune system that causes the airway passages to become inflamed. The muscles around the airways also tighten. Symptoms include coughing, wheezing, shortness of breath, rapid breathing, and chest tightening. Determining which allergens are causing asthma symptoms is essential so people can avoid these triggers and control asthma.

    Allergic asthma is an overreaction of the immune system to a substance (allergen) that results in symptoms of an asthma attack: difficulty breathing, wheezing, chest tightness, and coughing. Allergens that can cause allergic asthma attacks include pollen, mold, animal dander, dust mites, cockroaches, and certain chemicals.

    An attack may occur from a few minutes to an hour after exposure to an allergen or as long as 4 to 12 hours later. Controlling a person's exposure to substances that trigger allergic asthma attacks may prevent the attacks or help make them less severe. Also, there are medicines to help reduce the reaction to the allergen.
