What are the connections between allergic rhinitis, recurrent URTIs, sinusitis, and otitis?
Allergic rhinitis, recurrent URTIs, sinusitis, and ear infections (otitis) are closely connected because they affect the same airway passages of the nose, sinuses, and ears. Allergic rhinitis causes ongoing nasal swelling and blockage, which makes it easier for infections to occur repeatedly. Blocked sinuses can lead to sinusitis, and poor drainage of the Eustachian tube can cause ear infections and ear fullness. Treating nasal allergies early and properly can help prevent frequent infections of the sinuses and ears.
