text: Rhinitis can be broadly classified into allergic and nonallergic rhinitis. Some forms of rhinitis are not easily classified as either allergic or nonallergic, and sometimes, there also appear to be an overlap of both allergic and nonallergic rhinitis (sometimes referred to as 'mixed' rhinitis). The classification and diagnosis of nonallergic rhinitis is challenging due to its diverse etiology,  and it is also not well understood compared to the allergic type.
