What are common symptoms associated with allergic rhinitis?

The common symptoms associated with allergic rhinitis primarily include nasal congestion and a runny nose. Allergic rhinitis occurs when allergens, such as pollen, dust mites, or pet dander, trigger an immune response in the nasal passages. This response leads to the inflammation of the nasal lining, causing increased mucus production, which results in symptoms like a runny nose and nasal congestion. Individuals may experience other symptoms like sneezing, itchy eyes, and postnasal drip as well, but the most prevalent indicators are indeed nasal congestion and a runny nose. These symptoms are specific to the upper respiratory tract and help differentiate allergic rhinitis from other conditions that may involve similar features but are caused by different pathologies.
