Adding DPP4 inhibitors (e.g., sitagliptin) to metformin significantly improves glycemic profiles (fasting blood sugar and HOMA-IR) in women with PCOS compared to metformin alone.

If metformin alone isn't controlling your blood sugar or insulin resistance, adding a DPP4 inhibitor (like sitagliptin) is a clinically supported next step. This combination targets glucose metabolism more effectively than metformin alone in PCOS patients.

Why this rating

Based on a systematic review of 16 RCTs, but the review explicitly states a meta-analysis was not conducted due to heterogeneity.
