Answer
Allergic asthma is an airway inflammation caused by the immune system’s allergic reaction to certain substances, leading to airway narrowing and difficulty breathing. Allergens may include inhaled substances such as cold air, pollen, dust mites, as well as certain foods and medications. This inflammation causes susceptible individuals to experience recurrent attacks of wheezing, shortness of breath, chest tightness, or coughing, which often worsen at night and in the morning. The airways become hyperresponsive to various stimulating factors.
