Children get up in the morning to identify the cause of nosebleeds, may be physiological, may also be pathological; physiological reasons need to adjust the lifestyle, pathologically caused by the need for targeted treatment under the guidance of a doctor, such as drug therapy. 1. Physiological: If the humidity of the environment in which the child sleeps at night is too low, the mucous membrane of the nasal cavity is also in a dry state when the child gets up, which will lead to an increase in the brittleness of blood vessels, and will easily lead to the phenomenon of nosebleeds when the child gets up in the morning. It is recommended to increase the humidity of the indoor environment at night, such as turning on the humidifier or the ground to put the water basin, generally can be relieved. 2. Pathological: chronic rhinitis, sinusitis and other nasal inflammation, can cause nosebleeds in the morning. Chronic rhinitis can use mometasone furoate nasal spray, as well as oral rhinitis particles. However, other factors, such as thrombocytopenia or coagulation disorders, cannot be ruled out. Therefore, if lifestyle modification is ineffective, we should go to the hospital in time to clarify the cause of the disease and follow the doctor’s instructions to standardize the treatment, do not blindly self-medication. All of the above drugs should be used under the guidance of a doctor.
