When a patient experiences dryness inside the nose, it can be affected by a variety of factors. Some patients may suffer from cold or suffer from respiratory viral infections that cause the onset of acute rhinitis symptoms, and a certain degree of nasal dryness may occur in the early stages of acute rhinitis. At the same time, patients may also experience dryness inside the nose due to factors such as excessive recent smoking and drinking, excessive consumption of spicy, stimulating and inflammatory foods, or their own low water intake and insufficient vitamin intake. Patients may also be affected by excessive dryness of the surrounding air environment or pollution, as well as chronic rhinitis, chronic sinusitis and other factors, all of which may cause the symptoms of dryness inside the nose, and may further cause recurrent nasal bleeding.
