PCOS is most often defined according to the Rotterdam criteria, which stipulate that at least two of the following be present: irregular ovulation, biochemical/clinical hyperandrogenism, and polycystic ovaries (seen in the MRI scan above). Insulin resistance is part of the pathogenesis of PCOS, and insulin resistance is associated with T2D in PCOS.
In fact, PCOS is an independent risk factor for T2D, even after adjustment for BMI and obesity. Even normal-weight women with PCOS have an increased risk for T2D. More than half of women with PCOS develop T2D by age 40.
Even though family history and obesity are major contributors in the development of diabetes in patients with PCOS, diabetes can still occur in lean patients with PCOS who have no family history, mainly secondary to insulin resistance.
The Endocrine Society recommends that all individuals with PCOS undergo an oral glucose tolerance test every 3-5 years, with more frequent screening for those who develop symptoms of T2D, significant weight gain, or central adiposity. In guidelines published in 2015 by the American Association of Clinical Endocrinologists, the American College of Endocrinology, and the Androgen Excess and PCOS Society, an annual oral glucose tolerance test is recommended for patients with PCOS and impaired glucose tolerance, whereas those with a family history of T2D or a BMI above 30 should be screened every 1-2 years.
Management of T2D with PCOS is similar to that of T2D without PCOS. Accordingly, metformin and lifestyle changes are the treatments of choice; any antidiabetic agent may be added in patients who do not achieve glycemic targets despite treatment with metformin.

A 36-year-old woman presents with recent unintended weight loss of 12 lb in 2 months. Currently, she weighs 153 lb (BMI 24.7). She complains of increased thirst, increased urination, lack of energy, and fatigue.
Metabolic workup reveals that A1c is 7.1%, fasting blood glucose level is 131 mg/dL, oral glucose tolerance test level is 210 mg/dL, and random blood glucose level is 215 mg/dL, all of which are diagnostic for type 2 diabetes (T2D). She has no family history of diabetes.
A lipid panel shows a low-density lipoprotein cholesterol of 140 mg/dL, high-density lipoprotein cholesterol 38 mg/dL, and triglycerides 210 mg/dL. Blood pressure is 150/95 mm Hg.
The patient had been diagnosed with polycystic ovary syndrome (PCOS) at age 33, during a workup for infertility. At the time of her PCOS diagnosis, she weighed 190 lb (BMI, 30.7). She gave birth to an 8-lb son 14 months ago.
