And its quite difficult to share my knowledge on this over here. With PCOS, you can learn new thing every day and I mean it! For the question you have asked: I got this info: Some women with easily moved hormones or hormones that are pretty close to normal can see signs of menstruation fairly quickly with Metformin. Others have to be more patient with their hormones while they get re-aligned. About 50% of women begin having regular ovulatory menses after 6 months of treatment. For women with PCOS treated with metformin alone, about 25% begin regular menses within 3 months,and about 50% to 95% begin regular menses within 6 months. Metformin is highly effective in normalizing menstrual cyclicity in women with PCOS, especially with a treatment duration of 6 months or longer.... Also you may now want to know Why you are on a diabetic drug? Here is the answer: Met is an insulin regulator. A large number of PCOS women (although not all...) have insulin resistance, where their bodies do not use the insulin their body produces efficiently. As a result, the body over-produces insulin to get their blood sugar down. So the diabetic drug Metformin/Glucophage works well with Insulin Resistant (IR) women because it opens the cell doors and helps your body use insulin more efficiently. I would like to tell you few more things: Firstly the best doctor you must refer to for PCOS is 'Reproductive Endocrinologist' or a 'Fertility Specialist'. These are the best medical professionals to deal with pcos in terms of health and changing to a healthier life style.. As you have pcos, it is best to keep yourself up to date and ready with necassary knowledge about this syndrome. As it not only affects fertility but also your entire health............Keeping yourself aware will also make you positive and you can even reason why a particular doc put you on some particular treatment. 'cuz believe me its not easy to find docs who actually understand pcos in all its aspects.............. Very frankly it won't be possible to tell you all what I know in this space so I would suggest you do search the net, I can give you the links I like......one being: You may be concerned about other health problems too but you know once you have control over your lifestyle, things will be fine and almost normal. You should try implementing healthy habits (regarding food n exercise) in your daily shedule and believe me it Only does good to all people who try it. I have pcos, I felt really lonely till I came to know a lot of women have this. I got a lot of support from this forum: Also one wonderful n Very Informative worldwide group I found recently is In this group you will find an entire forum about Metformin where also its FAQs are answered and also women using this med have shared their experiences with metformin. Both are worldwide pcos support groups. A group of wonderful ladies having pcos and all at different stages of life dealing with pcos, trying to conceive.... You can ask any question related to general health of women or any question relating to pcos. You'll get a first hand experienced advice as there is always someone to answer. And some women here are really knowlegeable. If you sign in these forums, don't forget to post an introduction so that all ladies know you and I am sure you'll be welcomed warmly. In the end, dear you don't have to be scared by all this! I know its easier said than done but believe me I have PCOS and I was just so scared n worried when I was first diagnosed in 2002 and now things are much easier, I am much more aware. Know that you are Not alone, there are many many women like you out there...... You can mail me any time, click on my name "Quetzal" that'll take you to my profile and then click "Email Quetzal".
