When the person is exposed to the allergen again, the allergen binds to the IgE antibodies on the mast cells, causing the mast cells to release chemicals, including histamine.

Allergies can range from mild (like seasonal hay fever) to severe and life-threatening (like anaphylaxis, a severe systemic reaction).
