Summary
This study aims to learn more about blood sugar patterns in women with Polycystic Ovary Syndrome (PCOS) using a continuous glucose monitor (CGM). Researchers will compare women with and without PCOS to see how their blood sugar differs in daily life. They will also test whether wearing a CGM for 90 days can help improve blood sugar and reproductive health. About 56 women aged 18-45 will participate.
