The doctor will look into the child’s medical history and will carry out a detailed physical examination in order to find the cause of the precocious puberty, so as to evaluate the appropriate course of treatment for that specific cause. The doctor will likely conduct an x-ray to determine bone age, perform a blood test, and in some instances, may carry out an ultrasound on the ovaries or an MRI scan on the brain to determine whether there is an ovarian tumor or a problem within the brain. If the doctor is unable to determine the cause, but still detects abnormal hormone production, the doctor will work to limit the on-set of early puberty by giving medications (injections) which can prevent the brain from releasing the hormones that causes children to develop early, and allowing the child to develop and grow at an appropriate rate. This injected medication must be administered monthly until the child’s bone age corresponds to his or her real age, and the child is at an appropriate age to begin puberty. When this treatment is discontinued, the production of hormones will resume as normal.
