What is non-allergic rhinitis?
Non-allergic rhinitis includes chronic sneezing and nasal congestion with no apparent cause. The symptoms of nonallergic rhinitis are similar to those of allergic rhinitis (hay fever) without the usual signs of an allergic reaction.
Non-allergic rhinitis can affect children and adults, although it is more common after the age of 20. The triggers of non-allergic rhinitis symptoms vary and may include certain air odors and irritants, changes in weather, certain medications, foods or chronic conditions.
The diagnosis of nonallergic rhinitis is confirmed after an allergic cause is ruled out. This may require blood tests or skin tests for allergies.
