LSGMSU1 is right. There are studies which indicate that Met helps lower male hormone levels and brings about regular ovulation in thinner cysters too.
My BMI has always been normal ... 23-24 range. And so my gynaec has prescribed me with only 500 mg Met per day. I've been on it for 4 months now. It has made me lose a few Pounds, but my cycles are regular, if a bit long-ish (40-50 days).
BTW I recently met my gynaec again with a print-out of that thin cysters and Met article. Surprisingly (or maybe I'd just become a little cynical after reading the experiences of many cysters here!), she seemed very open to the idea. She read the article carefully, twice ... and showed it to her assistants (a couple of them are always around when she checks patients).
But then she said that those studies were conducted on American women (who are, on an average, bigger and heavier) and would not be valid for Indian women. Type II Diabetics in India are also not prescribed more than 1000 mg per day. She says many of her patients who she has prescribed 1000 mg Met to complain of weakness and fatigue and she's had to reduce the dosage to 500 mg.
She asked me to take a few tests - blood sugar and serum prolactin. My prolactin levels have been a little on the higher side in the past, and she'd prescribed B-Long (Pyridoxine Hydrochloride) tablets ... which also worked well. I'm hypothyroid and that means my prolactin levels tend to go high and that also inhibits ovulation. She's asked me to come see her with the test results - which I plan to do in a day or two.
But she seems open to increasing dosage and I'm glad that my gynaec is so open minded
