Frequent nosebleeds are a very common phenomenon among children. There are many reasons for nosebleeds, specifically the following: First, many children have the bad habit of picking their nose with their hands. Our nasal cavity comes with a protective film, and many children have the habit of picking their nostrils, which is very bad, which will not only bring bacteria into the nasal cavity, but also lead to damage to the nasal mucosa, which causes congestion leading to nosebleeds. Secondly, allergic rhinitis. Some allergic reactions and their combined infections can also lead to nasal congestion. Usually allergic rhinitis has symptoms of old nasal mucosa ulceration, and slight rubbing of the nose at this time may lead to ruptured nasal mucosa and nosebleeds. Allergic rhinitis can also cause an itchy sensation that prompts the child to touch the nose, which can also lead to nosebleeds. Some children may also have some vascular deformities and congenital developmental problems that cause repeated bleeding from small blood vessels, which in serious cases require specialist ENT treatment. Finally, in addition to the above causes, nosebleeds in children may also be a manifestation of other organ pathologies, so if your child has frequent nosebleeds and can’t stop them, you need to go to the hospital for relevant examinations and timely discharge of pathological factors.
