Intensive lifestyle modification (diet and exercise) is the most effective intervention for preventing type 2 diabetes in women with PCOS who have impaired glucose tolerance, outperforming pharmacological agents like metformin.
If you have PCOS and impaired glucose tolerance, prioritize lifestyle changes over medication. Aim to lose 5-7% of your body weight through a healthy, low-fat diet and at least 150 minutes of moderate exercise per week. This approach is more effective at preventing diabetes than taking metformin alone. Metformin may be considered if lifestyle changes are insufficient, but lifestyle is the primary treatment.
The panel recommends that... Those with IGT should be screened annually for development of type 2 DM. PCOS patients with IGT should be treated with intensive lifestyle modification and weight loss and considered for treatment with insulin-sensitizing agents.
Why this rating
Based on extrapolation from high-quality RCTs in general high-risk populations (DPP, Finnish Diabetes Prevention Study) applied to PCOS context by expert consensus.

- Women with PCOS have a significantly higher risk of developing gestational diabetes mellitus (GDM) compared to control women, with PCOS being an independent risk factor.Strong
- Women with PCOS should undergo screening for impaired glucose tolerance using a 2-hour oral glucose tolerance test (OGTT) rather than fasting plasma glucose alone, as fasting glucose misses a majority of cases in this population.Good
