Overview
Pathophysiology
Rhinitis is caused by chronic or acute inflammation of the mucous membrane of the nose due to viruses, bacteria or irritants. The inflammation results in the generating of excessive amounts of mucus producing a runny nose, nasal congestion and post-nasal drip.
Rhinitis is caused by an increase in histamine. This increase is likely caused by airborne allergens. These allergens may affect an individual's nose, throat, or eyes and cause an increase in fluid production within these areas.
Rhinitis is considered IgE-mediated when the sufferer is classified as having allergic rhinitis.
