Allergic rhinitis is one of the most common allergies.

Allergic rhinitis An allergen is something that triggers an allergy. When a person with allergic rhinitis breathes in an allergen such as pollen, mold, animal dander, or dust, the body releases chemicals that cause allergy symptoms. Hay fever involves an allergic reaction to pollen. Plants that cause hay fever are trees, grasses, and weeds. Their pollen is carried by the wind. (Flower pollen is carried by insects and does not cause hay fever.) Types of plants that cause hay fever vary from person to person and from area to area.
