I have PCOS and had realize lap band surgery DEC 09, I have lost 120lbs and even after all that weight loss I still have the exact same symptoms as before. I found out recently after stopping my bcp in the effort to try to have my first child. I stopped my bcp in Oct last year and in a matter of 2 months or so I gained 25lbs without doing anything different. I had been able to maintain my weight loss for 2 years with no problems so I knew something was going on so I went to see my doctor and she said that bcp's are a treatment for pcos well then it all made sense to me. I have the insulin's resistance and that makes your body turn that extra insulin's in to fat so once I talked to my doc and had some blood work I was put on metformin to help control everything. I started out at 500mg 2 times daily and now I am taking 500mg 4 times daily. I have been on them for about 3 weeks at the lower dose and just started the new dose so I will share as times goes on what good happens. But to answer your question wls did not make my pcos go away and if it did there wouldn't be a support group here I guess. So weight may be a factor but it certainly isn't the only factor. Have you already had surgery?
