Question
My daughter is 9 and a half years old and has started menstruating. Is this a sign of precocious puberty? She is currently 1 meter 45 cm tall. Can she still grow taller?
Answer
Generally speaking, the onset of menstruation in girls is a sign of sexual development maturing. If menstruation begins at this age, it may indicate precocious puberty. Once girls with precocious puberty start menstruating, the likelihood of further height growth is very low. It is recommended that you take your daughter to see an endocrinologist for tests of growth hormones and sex hormones, as well as an evaluation of the epiphyseal line, to assess whether she can still grow taller.
