Allergic Asthma Overview

What Is Allergic Asthma?

Allergic asthma is the most common type of asthma. There are approximately 24 million people in the US with asthma. About 60% (6 out of 10) of people with asthma have allergic asthma. For school-age children, this number is closer to 80%. Allergic asthma is caused by breathing in an allergen, which is a substance that can cause an allergic reaction. Allergens that cause allergic reactions, such as pet dander or dust mites, are commonly called allergic triggers.
