Patient's question:
The child is 6 years old and has been prone to nosebleeds since childhood. Now, they are occurring more frequently, and the child often has a blocked nose on one side. Even a slight chill can trigger a nosebleed. What could be the cause? The doctor said it's due to eroded nasal mucosa and prescribed a nasal spray, but it hasn't shown any improvement! Should any specific tests be conducted?Doctor's answer:
1. Nosebleeds in children are very common, most often occurring in children aged 4 to 10, while infants rarely experience them again. The majority of causes for pediatric nosebleeds are erosion or ulcers of the nasal mucosa that damage the arterial capillaries on the mucosa, leading to nosebleeds.2. The most common site of nosebleeds in children is the anterior inferior part of the nasal septum, where there is a network of arterial capillaries. This area is easily affected by airflow and temperature changes. Factors such as rapid airflow, dry air, and hot weather can cause the mucosa in this area to be damaged, resulting in the rupture of capillaries within the mucosa and subsequent bleeding. Additionally, if a child has a habit of picking their nose, it can more easily cause damage to the nasal mucosa, leading to bleeding.
