I am on metformin because I have type 2 diabetes as well as pcos. But I do know that metformin is used to treat pcos even if there is no insulin resistance or diabetes. I'm no medical expert, but here is the reason why, to the best of my knowledge...
The hormones that cause the pcos symptoms travel through the bloodstream with insulin (they are kind of paired up). When you are insulin resistant, your body is not matching up the insulin and the glucose like it should be. Therefore, you don't process the insulin or the other hormones. Taking metformin makes that matching up happen. So, even if your glucose is normal, taking metformin can help more insulin (and other hormones) get processed so that the symptoms of pcos improve. Basically, it revs up your metabolism.
The good thing about metformin is, unlike other diabetes medications, it is very unlikely that your blood sugar will go too low.
Taking metformin has made a huge difference for me. Not only are my sugar levels more stable, but I have been able to lose weight when I couldn't no matter how hard I tried before. And I believe that its the medicine kick-starting my system that has made the difference.
I had really bad side effets on the regular release, but now I take the extended release and I'm fine. Hope this helped!

Dream as if you'll live forever. Live as if you'll die today.
If you have to tell someone how bad you want it, then you haven't shown them how hard you already work for it.
Whether you get what you want isn't what defines you. It's how you go about your business.
