Question
A four-year-old child has been experiencing frequent nosebleeds recently. Does this indicate a health problem?
Answer
The causes of nosebleeds in children are diverse and differ from those in adults. The most common causes include injuries such as a blow to the nose or a fall, severe cough (severe cough), sneezing, or picking the nose, which may lead to nasal mucosal ulceration. Second, nasal foreign bodies, such as toys, paper balls, or fruit peels inserted into the nose, can also cause nasal mucosal ulceration and trigger bleeding. Additionally, nasal inflammation leading to the accumulation of secretions can cause dryness, itching, pain, and discomfort. Children may scratch their noses due to these symptoms, leading to nasal mucosal bleeding. Nutritional imbalances or vitamin deficiencies, especially those caused by picky eating leading to deficiencies in vitamin C, K, or calcium, are also common causes of nosebleeds in children. In rare cases, benign or malignant tumors, as well as blood diseases such as leukemia, hemophilia, and aplastic anemia, may cause nosebleeds due to impaired clotting function.
