Precocious puberty is when sexual and physical maturation occurs earlier than normal. It can begin as early as age 6-7 in girls and before age 9 in boys. This is caused by the early release of hormones from the hypothalamus and pituitary gland. Treatment aims to stop further sexual development and rapid growth to allow children to reach their full adult height. Medications that block sex hormones are commonly used, and can help reverse physical changes and return behavior to age-appropriate levels. Precocious puberty affects girls more often than boys and carries health risks if not properly treated.
