What are Allergies?
Allergies are abnormal physical reactions you experience when you are exposed to substances (allergens) to which you have developed an allergy. These substances are usually harmless and do not produce symptoms in non-allergic people. The response produces symptoms that may be mild to life-threatening.
What Kinds of Things are Allergens?
ANYTHING to which a person becomes allergic is an allergen. Certain substances are more likely to become allergens. For example, ragweed pollen, cedar pollen. Other substances may be medications, dust, mold, animal dander, feathers, insect venom, air-borne chemicals, etc.
Most commonly, allergies begin in childhood. However, allergic symptoms may develop at ANY age.
