(HealthDay News) -- Nosebleeds are common during childhood, especially during the preschool years. Though they can be scary, they usually aren't caused by a serious problem.
The American Academy of Pediatrics says common causes of nosebleeds include:
- Allergies or a cold, which can lead to nasal swelling or irritation.
- Trauma to the nose, from blowing too hard, picking or putting an object in the nose.
- Exposure to a very dry environment or harsh fumes.
- An abnormal anatomical structure of the nose.
- An abnormal growth inside the nose.
- A blood-clotting problem.
- Taking medication that dries out the nasal passages.
