Question
Why do children often have nosebleeds?
Answer
Acute febrile infectious diseases are the main causes of nosebleeds in children, especially upper respiratory infections. When a high fever occurs, there is vasodilation and swelling of the skin and mucous membranes throughout the body. The nasal mucosa also undergoes this pathological change. When the nasal mucosa is acutely congested and swollen, it is more prone to break and bleed. The nasal cavity’s mucosal blood vessels are superficial, and when there is severe fever, combined with the external force of forcefully blowing the nose, the blood vessels under the mucosa will break and bleed.
