There are several possible causes of this abnormal expansion of the blood vessels or inflammation. The first one is that the nerve endings in the nose may be hyperresponsive, similar to the same way wit the lungs react in asthma.

Other causes are health problems that lead to nonallergic rhinitis.  They can be short-lived or chronic problems. Nonallergic rhinitis triggers include:

  • Environmental or occupational irritants. Dust, smog, secondhand smoke or strong odors, such as perfumes, can trigger nonallergic rhinitis.
