EXTRINSIC ASTHMA OR INTRINSIC ASTHMA?

Extrinsic and intrinsic asthma are also called allergic and nonallergic asthma. Extrinsic or allergic asthma is triggered by an allergen, while intrinsic or nonallergic asthma is triggered by something other than an allergy. Because the symptoms of both kinds of asthma are similar, the two conditions can be difficult to decipher, and you may need to examine potential triggers to tell the difference. When asthma symptoms mimic seasonal allergies or you’re already experiencing allergy symptoms, it usually indicates extrinsic asthma. Asthma symptoms that accompany or follow an upper respiratory virus or infection, oral infections, or exercise are usually caused by intrinsic asthma. It is possible to have both intrinsic and extrinsic asthma and seasonal allergies all at the same time.

P.S. Age can point to whether asthma is extrinsic (usually develops during childhood) or intrinsic (usually develops in middle age or later).
