Patient's question:
Doctor, my child is four years old. Recently, I've noticed that he often gets nosebleeds. Is there any illness associated with this?Doctor's answer:
The causes of nosebleeds in children are different from those in adults. The most common cause is trauma, such as falling or bumping the nose, severe coughing, sneezing, or nose picking, which can lead to erosion of the nasal vestibule. The second is nasal foreign bodies, such as toys, paper balls, fruit peels, or melons, inserted into the nasal cavity, causing erosion of the nasal mucosa and bleeding.Nasal inflammation with secretions accumulating in the nasal cavity can lead to dryness, itching, pain, and other discomforts. Children often pick their noses, causing bleeding of the nasal mucosa.
Nutritional imbalances or vitamin deficiencies, such as picky eating in some children, can lead to vitamin deficiencies (e.g., vitamins C, K, or calcium deficiency), often resulting in nosebleeds in children.
The least common cause is tumors, including benign or malignant tumors, or blood disorders such as leukemia, hemophilia, or aplastic anemia, which can lead to impaired blood clotting and cause nosebleeds.
