Pregnancy Induced Rhinitis

From Otolaryngology Online

Ellegard and Karlsson defined pregnancy rhinitis as nasal congestion in the last 6 weeks of pregnancy without signs of respiratory tract infections in the absence of allergy. It disappears within the first week after child birth. Relationship between pregnancy rhinitis and allergic rhinitis is unclear, but studies have revealed that the incidence of sinusitis is more than 10 times greater in pregnant women.
