When children have dizziness and nosebleeds, the following causes are mainly considered: First, the child is likely to have systemic malnutrition, lack of vitamins, lack of clotting factors, so the coagulation function is not good, and after the lack of nutrition the patient will feel always weak and often have symptoms of dizziness; Second, sometimes it is because there may be hemangiomas inside the nasal cavity, and prolonged bleeding will easily lead to the formation of anemia, and dizziness will often occur. It is best to go to the hospital for detailed examination to clarify the cause and symptomatic treatment. The nosebleed needs to be stopped and erythromycin cream can be applied locally so as to promote the healing of the mucous membrane, the nosebleed is reduced and the dizziness symptoms should improve to some extent. If it is general malnutrition, further examination is often needed to actively supplement nutrition.
