Allergic rhinitis is an allergy reaction that affects the nose and upper airways. It is often called hay fever, even though it is not caused by hay and does not usually cause fever.
Common triggers
Triggers can include pollen, dust mites, mold, pet dander, smoke, or other airborne irritants. Some people have seasonal symptoms, while others have symptoms throughout the year.
Common symptoms
Symptoms can include sneezing, runny nose, nasal congestion, itchy eyes, watery eyes, postnasal drip, cough, or tiredness from poor sleep.
Allergic rhinitis can overlap with asthma, sinusitis, and eczema because all involve immune and inflammatory responses.
