Precocious puberty has many causes, including genetic factors, conditions during the mother's pregnancy, or congenital pituitary abnormalities, all of which can lead to the condition. When precocious puberty occurs, it is necessary to conduct diagnostic tests including MRI of the pituitary in the head, bone age assessment, ultrasonography of the gonads, and blood hormone level measurements to determine the appropriate treatment. Mild cases can be managed through a balanced diet, appropriate exercise, and rest. In some cases, oral Chinese medicine can be used if blood hormone levels are not severe enough to require other treatments, to help control the child’s sexual development. In severe cases, such as when a child's bone age is more than one year above their actual age, accompanied by abnormal blood hormone levels and changes in gonadal ultrasound, and significant loss in height, it may be necessary to administer injections of gonadotropin-releasing hormone analogs to control the level of sexual development. If there is a significant loss in height, it may also be necessary to combine this with growth hormone injections to treat growth.
