Quoting rpgmomma8404:" I'm wondering why they would put you on metformin for PCOS? I take it for diabetes. "
Women with PCOS don't digest sugars/carbs like most people do, so they gain weight and it messes with the hormones. Metformin helps to regulate it. At least, that's the way my doctor explained it to me. Also, women with PCOS are either borderline diabetic or already have diabetes. They don't know if PCOS causes diabetes or not yet, but it's a contributing factor for a lot of diabetes in women.
