PCOS is a disease that occurs after the onset of puberty. Body hair growth is under the control of adrenal glands
, and overfunctioning of the adrenal androgens is responsible for overgrowth of body hair (hirsutism
). You should take her for an evaluation by a general pediatrician
or a pediatric endocrinologist
, who may order tests of adrenal hormonal secretion before reaching a diagnosis.
