What is an allergy?
Allergies, according to Very well health, are an abnormal immune system response to foreign substances that are normally harmless.
Your immune system’s job is to protect your body against harmful substances. However, in people with allergies, your immune system identifies certain harmless substances as harmful, triggering a reaction to protect them from “attack”.
Causes
One can be allergic to different substances like dust, pollen, mould, animal dander i.e. shed skin, some foods, latex and certain medications. Other allergens include some metals, plant resin and insect stings.
