Patient's question:
Irregular, every few daysDoctor's answer:
Acute febrile infectious diseases are a common cause of nosebleeds in children, especially upper respiratory tract infections. When high fever occurs, blood vessels in the skin and mucous membranes throughout the body become congested and swollen. The nasal mucosa also undergoes this pathological change. Acute congestion and swelling of the nasal mucosa make it more prone to rupture and bleeding because the blood vessels in the nasal mucosa are superficial. Once severe fever occurs, combined with the external force of forcefully blowing the nose, the submucosal blood vessels can rupture and bleed.
