What kind of doctor treats Precocious Puberty?
A pediatric endocrinologist, a children's hormone doctor, usually treats precocious puberty. A child's regular doctor, called a pediatrician, often spots the signs first. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is precocious puberty?
Puberty is the time when a person's body changes from a child's body to an adult's body. Puberty usually begins between ages 8 and 13 for girls and ages 9 and 14 for boys. Precocious puberty is when these body changes happen earlier than normal.
Precocious puberty is rare, and many more girls are affected than boys. There are two main types. In central precocious puberty, a part of the brain called the hypothalamus starts puberty early. In peripheral precocious puberty, the ovaries, testicles, or adrenal glands make sex hormones too early.
Symptoms
In girls, any of these signs before age 8 means puberty is early:
- Armpit or pubic hair
- Breasts
- Faster growth
- A first period
In boys, any of these signs before age 9 means puberty is early:
- Armpit or pubic hair
- Growth of the testes and penis
- Facial hair, often first on the upper lip
- Muscle growth
- A deepening voice
Acne and adult body odor can also be early signs in both boys and girls. Children who start puberty too early may not reach their full height, because growth stops too early. Early development can also cause social and emotional problems.
Causes and who gets it
Most often there is no clear cause. Some cases are due to changes in the brain, genetic problems, or certain tumors that release hormones.
In most girls with the central type, there is no medical problem behind it. In boys, it is less common and more likely to be linked to a medical problem. Examples are a tumor, a brain injury, or inflammation (swelling), such as meningitis.
Contact with an adult's estrogen or testosterone cream can also cause it. Children should not take adult medicines or supplements that contain hormones.
How doctors diagnose it
Your child's doctor will take a medical history and do a physical exam. Blood tests may check hormone levels. The doctor may order an x-ray of the hand to see if the bones are maturing too fast. A CT or MRI scan of the brain or belly may check for tumors. Rarely, a blood test checks for a gene change that causes a rare type.
Treatment
Treatment depends on the cause. Some children get medicines that stop the release of sex hormones, which helps delay puberty. These medicines are given as a shot until the normal age of puberty. Surgery may be needed to remove a tumor.
For peripheral precocious puberty, treatment depends on the cause. It could mean removing the outside source of hormones, such as an estrogen cream.
Parents can help by explaining the condition and the treatment plan. Talking to a mental health worker or counselor may also help.
When to see a doctor
See your child's doctor if your child shows signs of early puberty. Report these signs if they start before age 8 in girls or before age 9 in boys. Also see the doctor if early development seems to cause problems in school or with other children. Early vaginal bleeding, especially bleeding before breast development, should be reported.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can check your child and refer you to a pediatric endocrinologist.
Common questions
Does precocious puberty affect height?
Yes, it can make a child shorter than expected as an adult. The bones of these children mature and stop growing earlier than normal.
Can precocious puberty be treated?
Yes, treatment can help stop puberty until the child is closer to the normal time for sexual development. Medicines that stop the release of sex hormones are given as a shot.
Is precocious puberty more common in girls or boys?
It is more common in girls. Boys are more likely to have a medical problem that causes it.
Can precocious puberty cause emotional problems?
Yes, it can. Children want to be like their friends. Early development can make them look different.
