(HealthDay News) -- Nosebleeds affect one in seven people during their lives, the American Academy of Otolaryngology says. They're most common among people aged 2-10, and aged 50-80.

The academy says the most common causes of nosebleeds include:

• Dryness, allergies or infections.
• Blowing your nose too hard.
• A blood clotting problem triggered by heredity or a current medication.
• A skull fracture or fracture of the nose.
• Tumors or hereditary blood vessel disorders.
