Will birth control or other medications help a woman with PCOS lose weight?

I have PCOS. I gained weight with the birth control pill. So yes you can gain weight. Metformin made me lose 72 pounds. So If you take it regularly it will help. But you will have to deal with the side effects of Metformin. My blood sugar has stabilized also. But I'd talk to your doctor or OB/GYN or an endocrinologist.
