Asthma and Allergy

Allergic asthma is asthma caused by an allergic reaction. It’s also known as allergy-induced asthma. People with allergic asthma usually start feeling symptoms after inhaling an allergen such as pollen. The Asthma and Allergy Foundation of America reports that more than half of people with asthma have allergic asthma. Allergic asthma is treatable in most cases. An allergen is a typically harmless substance such as dust mites, pet dander, pollen or mold. If you are allergic to a substance, this allergen triggers a response starting in the immune system. Through a complex reaction, these allergens then cause the passages in the airways of the lungs to become inflamed and swollen. This results in coughing, wheezing and other asthma symptoms
