What is precocious puberty? Precocious puberty (CPP) is defined as the onset of sexual development in children at a significantly earlier age, with girls showing secondary sexual characteristics by age 8 and boys by age 9. The overall incidence of precocious puberty in children is more common in girls, with a male to female ratio of about 1:4. The clinical manifestations of central precocious puberty are: secondary sexual characteristics appear before the normal age of puberty, accelerated height growth, early bone age, and early epiphyseal fusion. The gonads are enlarged and developed, and fertility is achieved. Why should I seek early medical attention for precocious puberty? Once a child is found to have signs of precocious puberty, parents should take the child to the hospital as soon as possible. Only through a physical examination by an experienced specialist and a series of special laboratory tests to clarify the child’s disease can the correct treatment plan be chosen for the cause. In addition, too many children with precocious puberty have early secretion of sex hormones, which cause early healing of the long bone epiphysis and eventually affect the lifelong height of the child in adulthood. If the child does not seek medical treatment in time, the epiphysis will heal to a certain extent, or the bone age will reach a certain level (generally considered to be above 14 years old), and there is not much room for height growth, and the best time for treatment will be lost. Therefore, whether from the treatment of the original disease or from the consideration of the child’s lifelong height, once the signs of precocious puberty are detected, it is very necessary to seek medical attention in time.
