Allergy-Induced Asthma: When Allergies Cause Asthma
Allergies and asthma are often thought to be unrelated conditions. However, in many cases there is a causal relation between the two. For instance, common allergens (like pet dander, dust, and pollen) trigger allergic inflammation in the lungs followed by more serious asthmatic symptoms. Doctors call this variety of asthma ‘allergy-induced asthma.’ How does an allergic response cause an asthmatic reaction? Many of us suffer from allergies or know someone who suffers from allergies of some kind. It’s a common sight when someone is exposed to an allergen they are known to react to, and as if on cue, the reaction follows. An allergic response occurs when the immune system mistakenly identifies a harmless allergen (i.e., cat dander) as an invader and releases antibodies. How ironic that It is this protective mechanism that leads to allergy symptoms of itchy eyes, hives, runny nose, headache, cough, and nasal congestion. If you also suffer from asthma, a simple allergic reaction can trigger wheezing and coughing due to tight and restricted lungs and lead to a full blown attack. Who’s most at risk of allergy-induced asthma? If you suffer from allergy symptoms resulting in hay fever (caused by the powdery pollen that’s produced by weeds, grasses, and certain trees), you may have a higher risk of also developing asthma.
