An allergy is a reaction to a substance that is usually considered harmless to non-allergic individuals. The body’s immune system identifies allergens as foreign invaders and produces IgE antibodies against them. Approximately 60 million Americans suffer from allergies. Different allergens are found throughout the United States and in varying concentrations. There is no place one can go to totally avoid allergens in the United States.

Allergies can develop at any age. Once someone is know to be allergy prone, they have a tendency to exhibit allergies anytime throughout their lifetime. Avoidance of an allergen is the most effective treatment for allergies. The development of specific allergies is related to repeated exposure to that allergen.
