Rhinitis is a common condition that affects the nasal passages. It is typically characterized by symptoms such as a runny or stuffy nose, sneezing, nasal congestion, and postnasal drip. There are a few different synonyms for rhinitis, including allergic rhinitis (also known as hay fever), infectious rhinitis (caused by a virus or bacteria), and non-allergic rhinitis (not caused by allergies). Other terms used to describe rhinitis include nasal inflammation, sinusitis, and nasal allergy. Treatment for rhinitis generally involves managing the underlying cause, such as avoiding allergens, taking antihistamines or decongestants, or using nasal sprays.
