Frequent nosebleeds in boys may be related to environmental dryness, nasopharyngeal fibrous hemangioma, nasal capillary hemangioma, allergic rhinitis and other diseases.
1. Dry environment: dry air, indoor temperature is too high, too dry, as well as long time in air-conditioned room makes indoor ventilation is poor, etc., cause nasal mucosa dry bleeding.
2. Nasopharyngeal fibrous hemangioma: it is the most common benign tumor in nasopharynx, which is composed of dense connective tissue, elastic fibers and blood vessels, and often occurs in young men aged 10 to 25, so it is also called “male adolescent hemorrhagic nasopharyngeal angiofibroma”. Due to repeated hemorrhage, patients often have different degrees of anemia.
3. Nasal cavity capillary hemangioma: the nasal cavity is rich in submucosal capillaries, and there are arterial and venous conglomerations in the anterior part of nasal septum, anterior end of inferior turbinate, and skin of external nose, etc. Boys are in the period of growth and development, and this performance is especially obvious. In trauma, chronic inflammation, adverse physical and chemical factors stimulation, often can occur often nosebleed.
4. Allergic rhinitis: allergic boys in contact with allergens, nasal mucosal edema, mucosal epithelial tissue brittleness increases, often in the emergence of nasal itching, sneezing, sneezing, runny nose symptoms, triggered by blowing the nose, rubbing the nose, and after the damage to the nasal mucosa, frequent nosebleeds occur.
Affected children should avoid picking their noses and other bad habits, and should be hydrated when exercising. When a boy has frequent nosebleeds, he should consult a doctor for a systematic examination to confirm the diagnosis.
