What causes central precocious puberty?

ANSWER

Most times, experts don't know, particularly in girls.

Sometimes, central precocious puberty is triggered by a medical problem. An underlying cause is more common in boys and children under age 6, especially if puberty is advancing rapidly. These can include:

  • Tumors and other growths, often benign
  • Brain injury, either from surgery or a blow to the head, that affects hormonal balances
  • Inflammation of the brain, sometimes from an infection
