Nosebleeds in children may be caused by nasal mucous membrane damage, allergic rhinitis, deviated nasal septum, etc., and often require general treatment, medication, surgery, and so on. 1. Nasal mucous membrane injury: it is often caused by the child’s love of picking his/her nose, which can be guided by education, and the child should avoid picking his/her nose as much as possible. 2. Allergic rhinitis: often easy to cause nasal itching, the child often rubbing the nose is easy to cause nosebleeds, usually need to use local mometasone furoate nasal spray, budesonide nasal spray, etc., to help relieve the inflammatory reaction of the nasal cavity, if necessary, can be added to the doctor’s orders, such as loratadine anti-allergy treatment. 3. Nasal septum deviation: mild nasal septum deviation generally does not cause nosebleeds, if the nasal septum deviation is more serious, resulting in nosebleeds, can be prescribed by the need to take surgical correction. If your child has a nosebleed, it may be caused by other reasons, so it is recommended that you go to the hospital in time to find out the cause of the nosebleed and then cooperate with the doctor to take treatment.
