There are many causes of nosebleeds in children, mainly related to the following factors: 1. The nasal mucosa of young children is fragile, and when the air is dry, it can cause bleeding of the nasal mucosa; 2. Trauma or foreign bodies in the nasal cavity can also easily lead to nosebleeds, while some young children have nasal inflammation or pick their nostrils with their favorite hands, which can easily lead to bleeding from injuries to the fragile nasal mucosa; 3, hemophilia and other blood system diseases, can also easily lead to nosebleeds in children. Therefore, if your child has frequent nosebleeds, it is recommended to go to the ENT department to find the cause and then treat the symptoms. In addition to actively looking for the cause and providing the appropriate treatment, you can also prevent the condition by taking relevant measures, such as paying attention to regulating the humidity and temperature in the room and using a humidifier. For children with a history of nasal bleeding during the dry season, families should have a supply of ophthalmic ointment of gentamycin, which can be applied evenly in the nasal cavity every day to moisten the nasal mucosa. Help children correct the bad habit of picking their nostrils and pay attention to avoid external damage. If your child has a cold, tonsillitis, pneumonia or mumps and other infectious diseases, you should actively treat them to avoid congestion and swelling of the blood vessels in the nasal mucosa and even bleeding from ruptured capillaries. In addition, we should correct the child’s habit of partial eating, drink more water, eat more vegetables and arrange the diet in a reasonable and scientific way.
