There are two types of allergic rhinitis: seasonal and perennial.
Allergic rhinitis.is an inflammation of the nasal passages caused by allergic reaction to airborne substances. Seasonal AR occurs in the spring, summer, and early fall, when airborne plant pollens are at their highest levels.
Reducing exposure to pollen may improve symptoms of seasonal AR.Preventing perennial AR requires identification of the responsible allergens.
