Precocious puberty

Overview

Precocious puberty typically begins before age 8 in girls and before age 9 in boys. Bones and muscles start to grow fast. The body changes in shape and size. And the ability to have a baby begins. The cause of precocious puberty often can't be found. Rarely, certain health problems may cause it. These include hormone disorders and tumors.

Symptoms

Precocious puberty symptoms can include fast growth, pubic or underarm hair growth, acne and adult body odor. Children who are born female have a first menstrual period and start to grow breasts. Children who are born male see the testicles and penis grow larger. They also develop a deeper voice and facial hair.

Treatments

If no clear cause of precocious puberty is found, medicine may be a treatment option. Medicine can stop the body from developing more until the usual age of puberty. If a health condition is found, treatment of that condition can delay puberty. Counseling can help a child or family manage the emotions and challenges of having this condition.
