If low estrogen is part of your list of issues, you might benefit from reading one or more of the books by
Dr Vliet.
Also if you have low estrogen and high FSH - you
might have something more like premature ovarian failure, or perimenopause or menopause. The array of symptoms that women with PCOS can have is quite variable - but I think often PCOS is characterized by an elevated LH:FSH ratio - so if you have an elevated FSH it
might mean somethings else -- it would be up to a doctor of course to say for sure.
I was told that I have "premature ovarian decline with normal FSH" as well as PCOS (my LH:FSH ratio is very typical of PCOS) - "premature ovarian decline" is not really an officially used diagnosis word in wide use as much as it is what my doctors office used to describe what I have -- I think it mainly means low estradiol or low ovarian hormones in my case -- I looked into Premarture Ovarian Failure because it sort of sounded the same. Elevated FSH is consistent with POF (although high FSH might could mean other things too
probably) - I was told that you really can't have POF without elevated FSH -- it would seem to me that low estradiol and missing periods might fit too - the rest I don't know about since I really did not go too far into looking into the possibility of FOS for myself. Again I don't know much about it but it might be worth an internet search for you to find out more.
Also - with low estrogen, especially if it started early, you might might want to ask your doctor if you need to get a bone density scan to make sure that loss of bone density is not a problem. (I have that too.)
Would you mind saying how old your are and at what age you think the problem you described began?
