An allergy is a condition that causes the body's defense system (immune system) to react too strongly to an allergen. An allergen is a substance that is harmless to most people but can cause a reaction in some people.
Allergies often affect the nose (allergic rhinitis), eyes (allergic conjunctivitis), skin (atopic dermatitis), and stomach. They can be mild, moderate, or severe. They cannot spread from person to person. Allergies can start at any age. In some cases, they may go away as your child gets older.
Symptoms depend on how severe the allergy is.
