Which condition is characterized by sneezing, nasal congestion, and clear rhinorrhea, particularly worse in the morning?

The condition characterized by sneezing, nasal congestion, and clear rhinorrhea that is notably worse in the morning is allergic rhinitis. This condition arises due to an allergic response to environmental allergens such as pollen, dust mites, animal dander, or mold.

In allergic rhinitis, the immune system overreacts to these allergens, leading to inflammation of the nasal passages and resulting in symptoms like sneezing and clear nasal discharge, which is distinctly different from the purulent discharge often associated with infections. The timing of symptoms worsening in the morning can be attributed to the accumulation of allergens during the night, especially if the patient sleeps in an environment where allergens are present, such as dust mites in bedding.

Understanding the context of allergic rhinitis is important, as it helps distinguish it from other conditions. For instance, viral rhinitis typically presents with a similar but shorter duration of symptoms and may include fever or more significant malaise, while sinusitis often has obstructive symptoms along with purulent nasal discharge. Chronic rhinitis encompasses ongoing symptoms but does not necessarily highlight the allergic nature or the significant morning exacerbation seen in allergic rhinitis.
