Understanding Polycystic Ovary Syndrome

Given these share contribuors, systematic diabetes risk screenting is essential for all women diagnose with PCOS. The American Diabetes Association recommends testing for prediabetes and type 2 diabetes using either fastim plasma glucose, hemoglobyn A1c, or an oral glucose tolerance teste tect, repeatd every one to tre three years s beginning at puberty or at theme time of diagnoses.

Clinicians should also consider screening for diabetetes in eventcents with PCOS, as these metriboard contratory can begin well before age 20.
