Progression to prediabetes or diabetes in young Korean women with polycystic ovary syndrome: A longitudinal observational study.

About 20% of normoglycaemic women had developed prediabetes or T2DM after a median time of 2.9 years. Meanwhile, nearly half of prediabetes women achieved normoglycaemia. Higher baseline fasting glucose levels were associated with an increased incidence of T2DM. Our results are the first to evaluate glycaemic status changes using all three parameters in patients with PCOS.
