Patient's question:
Symptoms: No bump or injury, but why is there nosebleed? What's going on?Onset Time: Last time was the second time this has happened.
Test Results: No medical examination at the hospital.
Doctor's answer:
Children's nosebleeds most commonly occur in the anterior lower part of the nasal septum. There is a network of blood vessels formed by arteries and veins in the anterior lower part of the nasal septum. The mucosa here is thin, and the veins lack valves, which is medically referred to as the nasal fragile area. Due to its anterior position, it is easily damaged when subjected to external force. There are many causes of nosebleeds, both local and systemic. Local causes include nasal trauma, anterior rhinitis, nasal foreign bodies, and nasal angiofibromas; systemic causes include upper respiratory tract infections, aplastic anemia, thrombocytopenic purpura, liver cirrhosis, vitamin C deficiency, hemophilia, and leukemia.
