A substance that causes an allergic reaction is called an "allergen". Allergens can be found in food, drinks or the environment.

Typical Symptoms

The immune system of a person with an allergy reacts to the allergen as though it were a harmful pathogen - such as an undesirable bacterium, virus, fungus or toxin.

However, the allergen is not harmful. The immune system has a simply become oversensitive to that substance.

When the immune system reacts to an allergen, it releases immunoglobulin E (IgE), a type of antibody. IgE is released to destroy the allergen.


Reducing exposure to allergens, such as dust mites, may delay or prevent allergy or asthma symptoms.

Avoid smoking and exposure to environmental tobacco smoke. Tobacco smoke should also be removed from work places.
