Hurdity - It seems a bit patronising to criticise a GP or (anybody else really) for not understanding natural selection or genetics.
Oh - I've just caught up with this thread. I must say I am offended by that personal remark - which is totally unfair

. Not sure why you have picked on me as you will see from this thread that many of us do criticise our GPs, and precisely for the reason that they are the medical professionals who we go to see to help us, diagnose us and prescribe medication for us as appropriate, and who have studied biology and medicine to a high level and should know what they are talking about. Therefore it is their responsibility to inform and not to mislead. OK in this case it wasn't serious - and I know some GPs for example prescribe the wrong HRT - which is a more serious error, but they are not beyond criticism! I do not see that as patronising in mine nor anyone else's post. As for " or (anybody else really) - well that was unnecessary as I was clearly criticising the GP for stating something as fact to a patient that is wrong. I would not dream of saying that for example to anyone on here and I hope that is apparent from my posts as I try to be as helpful as possible without criticim, as most of us do. Negative personal remarks like this can be quite upsetting.
There were two aspects being discussed - the evolution (or genetics) of menopause and whether it is "natural" and the consequences and undesirability of being oestrogen deficient. Fortunately no-one posting on the thread disagrees that being oestrogen deficient in menopause has detrimental health consequences in many cases, and that the length of time we are in it is far longer now than it ever has been. Also that there needs to be more understanding by GPs, in this and other overlapping hormonal issues that become apparent in women at middle age and beyond - ie thyroid hormone, testosterone, and to a lesser extent insulin - as well as the various chronic fatigue conditions and syndromes that I'm sure in many cases are due to our hormone deficiencies and inefficiencies of some of our endocrine organs as we age.
Taz - interesting link there - which I skimmed through quickly! I might have mentioned the nurturing bit (or at least intended to!) which is what I am inclined to go with but I see that is also just another theory (it never can really be tested in humans).
GypsyRoseLee - we've gone off on a tangent here! Have we? However it's great to be able to discuss it and hope you are in a better place in your cycle moodwise at the moment?
