Children with frequent nasal bleeding are clinically considered to have the following conditions: the first condition, children have developed very bad habits, often picking their nose with their hands, repeatedly picking their nose can easily artificially lead to arterial bleeding in the nasal septum lei area, which is very common. In the second case, some children have congenital anatomical abnormalities of the nasal cavity, such as the existence of congenital deviation of the nasal septum, or some children have acquired nasal bone fractures, nasal trauma, etc., which can easily induce local tearing and rupture of the nasal mucosa and thus bleeding. In the third case, some children have allergic rhinitis, chronic rhinitis, sinusitis, and the mucous membrane of the nasal cavity is in a state of congestion and erosion for a long time, plus the child often sneezes, and the stimulation of airflow can easily induce nasal bleeding, which is not too much at this time. In the fourth case, some children have foreign bodies in the nasal cavity, such as fava beans, rubber and other foreign bodies stuffed into the nasal cavity after not removed in time, the foreign body in the nasal cavity becomes a focus of infection, inducing local mucosal erosion, rupture, and thus bleeding. In the fifth case, some patients have blood-related diseases, such as leukemia, aplastic anemia, hemophilia, hypersplenism, etc., which also tend to induce bilateral nasal bleeding.
