IgE: The Underlying Cause
You know that an allergen can trigger your asthma symptoms. But what puts your body’s allergic response in motion? The answer is an antibody in your blood called immunoglobulin E, or IgE.
IgE and a case of mistaken identity
When you have allergic asthma, your immune system sees allergens as dangerous. To protect your body from these “dangerous” allergens, it produces more IgE. The allergens then attach to the IgE on the surface of certain immune cells. This releases chemicals that can cause inflammation and increase mucus in your airways. As a result, allergic asthma symptoms may begin, such as coughing, wheezing, and shortness of breath.Watch video: “How Allergens Lead to Asthma Symptoms & Attacks”
