Greater than 60% of rhinitis patients over the age of 50 suffer from a non-allergic aetiology. The causes of nasal obstruction are: 1  Infective rhinitis: acute rhinitis is often infective in origin. 2  Viral rhinitis is one of the most frequent causes of nasal obstruction. 3  Rhinoviruses, respiratory syncytial virus, parainfluenza and influenza viruses and adenoviruses are among the viruses most commonly identified.
Nasal congestion most commonly is the result of inflammation and swelling of the lining tissues of the nasal passages and sinuses. Less commonly, anatomical obstructions (for example, a deviated nasal septum, foreign bodies) may lead to nasal congestion.
