Having rhinitis and a cold does not necessarily lead to nosebleeds; colds can induce or aggravate rhinitis. However, if the mucous membrane of the nose is dry due to the irritation of rhinitis, nosebleeds may occur. Colds are mostly caused by viral infections, during the onset of which the body’s immunity can be reduced, resulting in an aggravation of the original rhinitis, more serious nasal congestion, runny nose, sneezing, and even fever and other symptoms. When the original rhinitis is more serious, or cold triggered by the inflammatory reaction of the nasal mucosa, there may be nasal mucosal edema, brittle, capillary dilatation rupture bleeding, resulting in the occurrence of nasal bleeding. It is recommended that patients cooperate with the doctor as soon as possible during the cold, eat more protein-rich foods, and should actively treat the original rhinitis to avoid aggravation of the condition.
