Why isn't it normal an is a sign of obsessiveness to want to understand exactly what - and why - goes on in our bodies?!! (LOL) Ameliagrey, I've never had that response to curiosity about biology ever before. Yes, I do accept that certain hormones affect mood and we need to live with this but don't you think it's hugely helpful to know exactly what hormones and how they interact with brain chemistry and the amygdala/ the limbic system and really 'get a handle' on what's going on?
My DCs are fascinated and constantly asking all kinds of questions about how the brain works, how biology interacts with the mind etc etc and in my family background, there are a lot of medics. or people in allied professions. So we're all used to talking about and understanding how body/mind works. DCs (all boys) know all about menstruation, gender differences etc etc and seem to find it helpful to know that if I've lost my temper with them, it's because of progesterone levels, not because of them!
Recently, when I've been irritable because of the stage I'm at in my menstrual cycle, it's been v helpful for me and everyone else to be able to voice the fact that my 'hormones are interacting with my brain chemistry and making mum like a prickly porcupine'. The more I explain why I'm moody to my DCs, the more they feel able to see it as a biological thing and not the underlying 'me' and then I also feel more separate from the mood rather than dragged along with it.
So I do find that greater knowledge leads to greater liberation. Is that really abnormal? I never thought of myself as anything other than average 
No one specialises in gynaecology in the wider family however and my late mother suffered awfully during her menopause.
I'm feeling a lot better myself, since making some life changes anyway but am still fascinated and would find it v useful to know precisely what goes on that elicits certain reactions in myself and other women. I'm not inclined to use a gynaecologist's valuable time just to ask them specific questions and am sure I can find the answers by doing some research myself but as MN is such a fund of brilliant information and there are lots of intelligent women posting here, then I thought I'd try this forum in the first instance.
I actually think this is partly a feminist issue and maybe should have posted in that section because I think that 'women's problems' have been under researched and when the medical profession was male-dominated, women were often seen as 'weaker' just because they'd have hormonally induced mood swings at different times of the month. I find knowing exactly what is the biological basis of these moods, liberating and interesting and am keen to know more.
I've always found in life that if you understand why something is happening and exactly what's going on, then making sense of it frees you up to detach and have more choice and control. I want to be able to apply this principle more fully to my perimenopause.
I'm someone who rarely if ever has needed any medication other than occasional paracetemol and for me, being able to understand why I might be experiencing a pain and what it signifies has often been enough for me not to need a painkiller - eg period pains! I know that may not be the way that feels right for other people however. It's just what works for me. I don't think I'd ever contemplate taking HRT and have never been on the pill or anything like that at all.
Anyway, I already feel much better since my OP and am still interested in finding out more about the biological basis to my perimenopause. I think that women benefit and are strengthened by being able to understand exactly what happens in their bodies rather than just trusting the doctor who advises them to have all the answers. It's like when you take you car in to be serviced: if you passively accept the mechanic's view on what needs to be done, without knowing why, you're in a weaker position than if you have a working knowledge yourself of what might be going on!
I find that understanding liberates us from confusion and alleviates guilt and that's what propelled me to research the specifics of perimenopause and beyond.
