Nasal bleeding in children is a relatively common phenomenon, usually due to dryness of the nasal mucosa, fragility of the nasal mucosa or malformation of the blood vessels in the nose, among other reasons. The frequency of nosebleeds in children is more than 3-5 times a week and is related to the air, weather or low water intake of the child, and whether the nosebleeds can be controlled by simple hemostasis. If the frequency of nosebleeds is too high and cannot be well controlled by simple treatment measures, it is necessary to visit an otolaryngologist and have a nasal endoscopy performed by a professional otolaryngologist to identify whether the nosebleeds are due to nasal mucosa problems or due to other problems. Hematological tests are also needed to determine if there are other complicating causes of the nasal bleeding.
