What causes nose bleeding in children?

Some children often have nosebleeds. Sometimes they have nosebleeds while they are sleeping, sometimes they have nosebleeds while they are playing, and some children have nosebleeds while they are sitting quietly. For some children, the bleeding can be stopped quickly, but for others, it is difficult to stop the bleeding. So, what causes nosebleeds in children?

Overall reasons

1. Acute infection: If a child suffers from a cold, tonsillitis, pneumonia, or an infectious disease such as scarlet fever or mumps, he or she will have a high fever. At this time, the blood vessels in the nasal mucosa will also become severely congested and swollen, and even cause capillaries to rupture and bleed. This nosebleed must be accompanied by a high fever.

2. Blood system diseases: When suffering from blood diseases, such as thrombocytopenic purpura, aplastic anemia, hemophilia, leukemia, etc., nose bleeding is often the earliest symptom. If the child has unexplained nose bleeding, parents should pay special attention.

Local causes

1. Trauma: Minor trauma such as picking or blowing the nose can damage the "Ritter's area" of the nasal septum and cause nose bleeding.

2. Inflammation: Local inflammation of the nasal cavity, such as acute and chronic rhinitis and sinusitis, can cause dilation or ulceration of the blood vessels in the nasal mucosa, leading to nosebleeds.

3. Tumors: Tumors in the nasal cavity, paranasal sinuses and nasopharynx are often rich in new blood vessels. If ulcers, tissue necrosis and secondary infection occur, nose bleeding will occur.

4. Climate factors: Dry climate causes dry and crusted nasal mucosa, which can cause nosebleeds.

5. Caused by allergies: Most children who are prone to nosebleeds have symptoms of allergic rhinitis. The nasal mucosa of allergic rhinitis often has erosion symptoms, and because of the itchy feeling, they often poke and rub the nose, causing injury to the nasal mucosa and bleeding.

There are many reasons for nosebleeds. Trauma, inflammation, getting angry, and blood diseases may all cause nosebleeds in children. If a child has repeated nosebleed symptoms, it should be taken seriously. It is best to take the child to the hospital for examination and determine the cause, then provide timely treatment. Do not delay the child's condition due to parental indifference.
