I am new to this site. I was diagnosed with PCOS in 1998 and began Metformin in 2000. I have been on it ever since. I just had a vaginal hysterectomy on December 1st (kept ovaries). My hysterectomy was for uterine fibroids and a prolapsed uterus - not for PCOS. I had to stop the metformin for the surgery, but started taking it again - having some of those awful side effects again too -bummer. Anyway, wondering if anyone has had a hysterectomy and kept taking metformin? What has been your experience?
