Nosebleeds, also called epistaxis (ep-ih-STAK-sis), involve bleeding from the inside of your nose. Many people have occasional nosebleeds, particularly younger children and older adults.

Talk to your doctor if you're having frequent nosebleeds, even if you can stop them fairly easily. It's important to determine the cause of frequent nosebleeds.
After the bleeding has stopped, to keep it from starting again, don't pick or blow your nose and don't bend down for several hours. Keep your head higher than the level of your heart.
