Precocious puberty is defined as the abnormal condition where secondary sexual characteristics develop before the age of eight in girls and nine in boys. The harm of this disease includes shorter adult height, earlier sexual behavior, and suppressed personality, among other effects. The principle of treatment primarily focuses on improving the child's adult height, with treatments mainly including medication and etiological treatment. If diagnosed and treated early, the prognosis is generally good, and the final adult height can be significantly improved. If treatment is not administered in a timely manner, and the epiphyses of the bones have closed, it may not be possible to alter the final height.
