Comorbidities and allergic rhinitis: not just a runny nose.

: Allergic rhinitis is rarely found in isolation and should be considered in the context of upper and lower airway disease. People with AR are at greater risk of suffering asthma, rhinosinusitis, and other related upper airway conditions. Most people with both nasal allergies and asthma report that their asthma gets better when their nasal allergies are under control. People with AR are more than twice as likely to suffer problems sleeping due to their nasal allergy symptoms.
