What are the causes of nosebleeds in children?

When a human organ bleeds, it cannot usually be seen in person, whereas nasal bleeding is easily detected. It is generally believed that the bleeding is caused by the dilatation and rupture of blood vessels in the nasal septal vascular plexus area,Among patients with nasal bleeding, children account for the majority, what is the reason for this? According to the analysis, the causes of nasal bleeding in children are generally the following: 1. Acute febrile infectious diseases. During childhood, some infectious diseases with acute onset and high fever often occur, especially upper respiratory tract infections are more common. When high fever occurs, the blood vessels of the skin and mucous membranes throughout the body become congested and swollen, and the nasal mucosa also undergoes such pathological changes. The acute congestion and swelling of the nasal mucosa is more likely to cause rupture and bleeding because of the thin nasal mucosa and superficial blood vessels.

2.Trauma. The nose is an organ exposed on the body surface, once trauma occurs, such as blows and bruises, the nose naturally bears the brunt. Under the impact of severe trauma, the blood vessels under the mucous membrane will rupture and bleed.

3.Picking nose. Strictly speaking, nose picking should also be included in the scope of trauma. Children often like to dig blindly with their fingers in the nasal cavity out of curiosity and difficulty, which is a bad habit that is not only unhygienic but also easy to cause local mucosal bleeding in the nasal cavity. The general digging site is under the front of the nasal septum, and there are many blood vessels in this area, many tiny blood vessels are interwoven into a series of mesh, like a spider web, the blood vessels are superficial and very fine, the site is in the nasal cavity mouth, as long as the hand digging, you can dig through the blood vessels. More than 90% of children’s nasal bleeding is here.

4, nasal foreign body. Normally, in addition to some secretion of nasal snot, there is no object blocking the nasal cavity, so that breathing is free and clear. But sometimes, children like to stuff some small objects in the nasal cavity, such as peanuts, melon seeds, kernels, soybeans, plastic paper, small metal toys, etc., because of playfulness and fun. Once these objects are stuffed into the nose and become foreign bodies, children can’t get them out themselves and are afraid to make a statement, so they are forgotten and stay in the nasal cavity for a long time. Some foreign objects swell and mold in the nasal cavity with water, causing nasal mucosa infection, erosion and bleeding, and sometimes under the bad stimulation of foreign objects, the nasal mucosa can also cause traumatic bleeding.

5, blood diseases. It is important to know that the blood in the human blood vessels to do neither bleeding, nor agglutination, all by some special factors in the blood. If under the action of certain factors, some factors in the blood will undergo a series of changes, so that the blood vessels and blood in the occurrence of bleeding, it is not easy to stop the coagulation. These are leukemia, hemophilia, thrombocytopenic purpura, aplastic anemia, etc., collectively known as blood disorders. This is a direct cause of nosebleeds in children and can cause recurrent, heavy bleeding.

6, rhinitis, paranasal sinusitis. Children are also prone to acute and chronic rhinitis and paranasal sinusitis. Once this inflammation occurs, the mucous membrane in the nasal cavity or paranasal sinus becomes congested and swollen, and from time to time there is mucopurulent nasal discharge, and under the stimulation of purulent nasal discharge, the blood vessels under the mucous membrane also bleed.

To prevent rhinorrhea in children, we should take appropriate measures for specific causes, such as actively treating acute febrile diseases, admonishing and educating children not to stuff their noses, changing the bad habit of nose picking, eating less food with internal heat, cooperating with doctors to treat inflammation of nasal cavity and paranasal sinuses, etc.
