Hi Karine
I remember you from a discussion I started previously. My wife is the same age and has been period free for the same time as you (literally - on the money!). She had been reluctant to take HRT for years (7 years of suffering TERRIBLY - we're talking job ending, relationship straining, awful physical effects etc) as she was terrified that if she took it and then stopped, she would go "back to square one". It was the flushes that changed her mind eventually - after yet another 2 consecutive days (every week) of being bed ridden due to excessive flushes and sweats, she decided to give it a go. The longer she went period free, the more the flushes increased. We had a consultation with a great GP who agreed to prescribe her some patches (the lowest risk form of it). They reduced her flushes and sweats within days. Honestly. I know you haven't had a hot flush yet and I hope that you don't, but the chances are, I'm afraid, that you eventually will and it may be at that point that you change your mind about HRT. The health benefits in a woman of your age massively outweigh the risks (obviously unless you're severely overweight/smoke/history of cancer in the family etc). I completely agree with you that HRT will "stop" the body from adjusting itself to lower levels of our hormones - and we were absolutely desperate to get through this without HRT, but when it came down to it, her quality of life was SO poor that it seemed the only option. We had tried various regimes of supplements etc for 6 years - managed to get her hair to stop falling out but apart from that it just wasn't cutting it (although god knows how worse she may have felt without all of her vitamins).
Yes - the decline in hormones is a natural thing, but remember that back in the day, women would usually die not long after menopause! We're now living for longer and taking some hormones will just (hopefully) ensure that we do so whilst feeling well and healthy.
It is such a personal journey and I genuinely hope that you start to feel better really soon without the need to take something that concerns you so much. The decision to go on HRT is so massive and for a lot of women.
I wish you all the very best
