How does non-allergic rhinitis affect the body?

Dr. Jeanne Morrison, PhD
Family Practitioner

Non-allergic rhinitis is caused by many things, including the common cold. About 1 billion people are affected by the common cold in the United States every year. In non-allergic rhinitis, the blood vessels expand in the nose, causing inflammation in the tissues that line the nose. This causes nasal congestion, or runniness and stuffiness, and postnasal drip. Non-allergic rhinitis symptoms are not triggered by allergies.

Non-allergic rhinitis is a bothersome condition, but it is not a serious, harmful disease. Complications like infection and nose polyps can develop in more severe cases, but these usually are not serious. Talk to your doctor if you are experiencing symptoms related to non-allergic rhinitis to discuss your treatment options.
