What is an Allergy?
Allergy is an immunological hypersensitivity mediated by immunoglobulin E antibody (IgE). It is not a disease itself, but a mechanism leading to conditions such as rhinoconjunctivitis, urticaria, asthma, and anaphylaxis. A normally harmless substance – like pollen, food, or cat saliva – will cause the immune system to defend the body against it. In an allergic reaction, the mast cells release a chemical called histamine, which is the primary cause of allergic symptoms.

When you’re exposed to the allergen again, these antibodies can release many immune system chemicals, such as histamine, that cause allergy symptoms.
