polycystic ovary syndrome
"I have just been diagnosed with having Polycystic Ovary Syndrome. Before the diagnosis I put on about 40 lbs just out of the blue within 8 months. I also had excess hair on my face, stomach and legs, and I only had about 6 periods in the last year. 

I went for a pelvic scan and for the last 9 days I have been taking Metformin (500mg twice a day) under the doctor's orders. Something is definitely happening because I had a period within 5 days of taking the medication and I've lost about 4 lbs in the last week. The side effects were annoying. I had a lot of gas and diarrhea for about 3 days. The side effects seem to have passed now. My overall experience with Metformin is fairly good so far. I am looking forward to seeing more results."
