DefinitionBy Mayo Clinic staff
Precocious puberty is when someone's body begins changing from a child into an adult too soon. The process of changing from a child into an adult is known as puberty, and puberty that begins before age 8 for girls and before age 9 for boys is considered precocious puberty.
Puberty includes rapid growth of bones and muscles, changes in body shape and size, and development of the body's ability to reproduce.
The cause of precocious puberty often can't be found. Rarely, conditions such as infections, hormone disorders, tumors, brain abnormalities or injuries may cause precocious puberty. Treatment for precocious puberty typically includes medication to delay further development.
