Question
Why does my child sometimes have nosebleeds at night? We’ve taken them to the hospital, but they haven’t found any cause. Their daily diet and afternoon naps are quite regular, and they don’t eat much snacks?
Answer
The most common cause of nosebleeds in children is skin breakdown in the nasal cavity due to nasal diseases, such as regional inflammation of the nasal mucosa, foreign objects, or tumors, which can lead to nosebleeds. Additionally, dry, hot, or cold weather may also cause the nasal mucosa to crack. Some children may have the bad habit of picking their noses, which can also lead to nosebleeds. Unbalanced diet leading to vitamin deficiencies is also one of the causes of nosebleeds. Other systemic diseases such as hypertension and blood system diseases may also be the cause of nosebleeds, with leukemia being the most common in blood system diseases. Besides severe liver disease causing serious impairment of blood coagulation function and other conditions, all these can lead to nosebleeds. Therefore, it is recommended to first visit the otorhinolaryngology department of the hospital to rule out nosebleeds caused by nasal diseases.
