Nosebleeds involve bleeding from inside the nose. Many people have nosebleeds once in a while. They tend to be more common in children younger than 10 and adults older than 35. Nosebleeds also are called epistaxes (ep-ih-STAK-seez).

Nosebleeds may cause concern, but they're generally only a minor annoyance. Typically, they aren't dangerous. Nosebleeds are thought to be frequent if they happen more than once a week.
