Some of the stimuli or triggers of asthma attacks include viral upper respiratory infections, pollen, dust mites, molds, animal dander, other environmental allergens, occupational chemicals, tobacco smoke, cold air, exercise, gastroesophageal reflux, sinus infections, emotional factors, and drugs such as aspirin, nonsteroidal anti‐inflammatory drugs, and beta blockers. Various chemical reactions occur to make your airways hypersensitive to dust mites. Each subsequent time you're exposed to dust mites your immune system will respond by causing airway inflammation. And it's this inflammation that causes asthma and allergy symptoms.

In asthmatic air-ways, several inflammatory cells are activated, including mast cells
In asthma, the dominant physiological event leading to clinical symptoms is airway narrowing and a subsequent interference with airflow. In acute exacerbations of asthma, bronchial smooth muscle contraction (bronchoconstriction) occurs quickly to narrow the airways in response to exposure to a variety of stimuli including allergens or irritants. 2018-01-01 · Allergic asthma is associated with airway inflammation and airway hyperresponsiveness.
