What are the different types of allergic rhinitis?

3 types. Perennial - year-round symptoms usually due to something in your home - house dust mites, animal danders, molds, cockroaches. Seasonal - symptoms occurring only part of the year due to outdoor stuff - tree, grass or weed pollens & molds. Intermittent - symptoms triggered by occasional exposure to things you are allergic to - typically someone else' pet when you visit their home.
Allergic Rhinitis. Seasonal, perennial, non-allergic, vasomotor, hormonal, medication-induced, gustatory.
