Nosebleeds occur when the blood vessels in the nose break down. While trauma and dry air are the most common causes of nosebleeds, some medical conditions such as sinusitis and certain medications, such as over-the-counter decongestant nasal sprays, can make the blood vessels in the walls of the nose fragile and prone to breaking down.
In children, nosebleeds are usually caused by bleeding close to the tip of the nose. They can be frightening; but it is a common condition in children.
Nosebleeds can also be caused by:
- Nose picking or blowing
- Colds
- Allergies
- Sinus infections
- Injury to the nose
- Overly dry air
- Foreign material in the nose
