What are the causes of frequent unilateral nosebleeds in children?

Nosebleeds (epistaxis) are a very common symptom—for example, caused by picking the nose, prolonged sleeping on electric heating pads, or frequent nose-picking. Please take note. So, what causes recurrent unilateral nosebleeds in children?

What Causes Recurrent Unilateral Nosebleeds in Children?

Recurrent unilateral epistaxis in children is most commonly due to rupture of the nasal mucosa. If the bleeding is minimal—such as mild nasal congestion or occasional spotting—it typically originates from the Kiesselbach plexus (also known as Little’s area), a region rich in capillary networks located on the anterior-inferior portion of the nasal septum. Although bleeding from this area is usually minor, it may occasionally involve small arteries, leading to more substantial hemorrhage.

If unilateral nosebleeds recur frequently, prompt evaluation by an otolaryngologist at a reputable hospital is recommended to examine the nasal mucosa. Additionally, maintaining nasal hygiene and moisture is essential. Regular nasal irrigation with warm isotonic saline solution can help restore normal mucosal function. Parents should instruct children not to pick their noses with their fingers, as this may cause mucosal trauma and secondary infection, thereby triggering recurrent epistaxis.

When children experience nosebleeds, they should avoid consuming spicy or stimulating foods and beverages. Instead, opt for lukewarm, nutrient-rich foods high in protein, vitamins, and iron—such as honey water, rice water, milk, or fruit juice—or soft, semi-liquid meals like congee or noodles. Spicy and hard-textured foods should be avoided; instead, emphasize fresh vegetables and fruits. We hope this information proves helpful. Wishing you good health and happiness!
