Frequent nosebleeds in little girls are mostly due to the fact that the mucous membrane of the nasal cavity is delicate and easily stimulated by dry and cold air or frequent picking of the nasal cavity, which leads to rupture and ulceration of the mucous membrane in the Lai area and capillary bleeding. The bleeding in children is usually small, stopping with a drip or with blood in the snot. In this case, you should keep the nasal cavity clean and moist, try to avoid contact with the stimulation of dry and cold air, do not stay in the air-conditioned room for a long time, and at the same time, you can use saline to rinse the nasal cavity to keep the nasal mucosa clean and moist. Develop good habits, do not often pick the nasal cavity with your hands, so as not to cause mucosal damage. In addition, you should go to the ENT department of a regular hospital to check the condition of the nasal mucosa and to do blood tests and coagulation system tests to exclude blood system diseases.
