A nosebleed happens when the blood vessels rupture in the lining of the nasal passages.
Pediatric nosebleeds are common, but that doesn’t make them less scary for you or your child. Children tend to have nosebleeds more often than adults because the blood vessels in the lining of their nasal cavities are closer to the surface, making them more likely to rupture and result in a nosebleed.
In most cases, a nosebleed is not a serious condition, and most children grow out of having them. However, in rare cases, a nosebleed could be a sign of a more serious problem, such as a severe head injury.
The most common causes of nosebleeds in children include:
- A common cold that irritates the lining of the nasal passages
- Exposure to dry air that dries out the nasal passages
- Injury to the nose
- Repeated nose-blowing
- Seasonal allergies
- Sinus infection
- Something stuck in the nose (for example, a child putting a toy in the nasal passage)
Rarely, a nosebleed is caused by a serious head injury, a tumor in the nasal passage or a bleeding disorder.
The main symptom of a nosebleed is bleeding that comes from one or both nostrils of the nose.
