An allergy is a reaction of the immune system to a foreign material that is normally not harmful to the body. Such foreign compounds are known as allergens. Any foods, pollen, or pet dander may be part of them.

The role of the immune system is to keep you healthy and fight harmful pathogens. It does this by targeting anything it thinks could put your body in danger. Depending on the allergen, this response may involve inflammation, sneezing, or a host of other symptoms.

Normally, the immune system responds to the environment. When your body finds things like pet dander, for instance, it should know it's harmless. In people with allergies to dander, it is viewed by the immune system as a foreign invader that assaults and damages the body.
