Abundant,colorless and watery nasal dischargemay indicate allergic rhinitis. Then a runny nose most often appears in the pollen season of allergenic plants and is the result of the release of the so-called inflammatory mediators, incl. histamine, which dilates the blood vessels of the nasal mucosa and increases their permeability. Additionally, there is itching of the nose, watery and itchy eyes, frequent sneezing. However, there is no elevated body temperature that is characteristic of a cold. These symptoms disappear once contact with the allergens is ceased. The exception is year-round allergic rhinitis, when allergens are present all the time in the environment (e.g. house dust mites).

Colorless and watery nasal discharge may also indicate an early stage of acute rhinitis. It is also caused by hyperemia and an increase in the permeability of the blood vessels of the nasal mucosa. However, later he changes character again.
