Patient's question:
Daughter is two months away from turning 10 years old and has started developing breasts. Height: 145 cm, Weight: 87 lbs. Children of the same age as her do not have as pronounced breast development as her. No check-up has been done yet. Is it precocious puberty? Thank you.Doctor's answer:
Hello, precocious puberty refers to girls who exhibit secondary sexual development abnormalities before the age of 8. Based on pathogenesis and clinical manifestations, it is divided into central precocious puberty and peripheral precocious puberty. The causes of hypothalamic-pituitary-gonadal axis dysfunction mainly include nutritional excess, environmental pollution, and visual stimulation. Clinical symptoms are observed before the age of 8 in boys before the age of 9, showing secondary sexual development. Examinations include bone age assessment, ultrasound examination, sex hormone testing, and GnRH or similar stimulatory tests.
