IgE is usually only involved locally, within the airway passages.
Triggers include stress, cold or dry air, smoke, anxiety, viruses or infections
Extrinsic
Sometimes called allergic asthma
Symptoms are triggered by an allergen (such as dust mites, pet dander, pollen, or mold). The immune system overreacts, producing too much IgE throughout the body. It’s the IgE that triggers an extrinsic asthma attack.
