What Is Allergy?
Allergies are hypersensitive immune responses to substances that either enter or come in contact with the body, such as pet dander, pollen or bee venom. A substance that causes an allergic reaction is called an "allergen". Allergens can be found in food, drinks or the environment.
Most allergens are harmless, i.e. the majority of people are not affected by them. Allergens can stimulate an immune response when you breathe in or touch the allergen, or by ingestion of food or beverage, or from injections of medication.
