What type of substance is typically found in the urine of a patient suffering from rhinitis?

In patients suffering from rhinitis, mucus is a typical substance that is found in the urine. Rhinitis involves inflammation of the nasal mucosa, which is characterized by increased mucus production in the nasal passages. This condition can result in an increase in mucus output from the respiratory system, as the body attempts to clear irritants or allergens. While mucus itself isn't directly found in urine, the condition signifies the body's overall response to inflammation or infection, which may affect other bodily functions, including urine composition.

This context helps distinguish mucus production as a key symptom of rhinitis. It’s essential to understand that other substances such as excess protein, white blood cells, or glucose in urine are generally indicative of conditions like kidney damage or infections rather than a direct symptom of rhinitis. Thus, mucus, representing the primary response to the irritation in the nose, aligns more closely with the symptoms of rhinitis.
