What is Precocious Puberty (Early Puberty)?

Early puberty is also called precocious puberty. Puberty is thought to be early in girls before the age of 8 and in boys before the age of 9. Most children with early puberty grow fast at first, but finish growing before reaching their expected adult height.

Early puberty will cause a child’s body to change much sooner than his or her friends. They may feel different than their friends and have hormone changes that may cause mood swings. Your child may feel uncomfortable with his or her body changes.

Helping your child deal with teasing from friends and boosting self-esteem are important steps to help your child adjust to these changes.

h3>Cause of Precocious Puberty

Early puberty is caused by hormones from the reproductive glands or special glands called adrenal and pituitary glands.

A family history of early puberty, genetic syndromes, brain injury, or brain cancer treatments may also be a cause.

Discuss the reason your child may be in early puberty with your child’s healthcare provider.
