As has been said lubylou - there is no knowing how anyone will react after stopping HRT!
I think Taz has put the main categories - and I doubt whether it is understood which group you will fall into, and whether taking HRT itself will influence how you will subsequently react.
I would agree that the overall health benefits, and the years of well-being from taking HRT, for most women far outweigh the future negative impact of symptoms - but of course if you are one of the unlucky ones that will continue to have them for years you might not think so.
However what if you were one of those who would have had them for years anyway? Surely it is still worth taking HRT for some years because at least you will have had those years?
Re the 50 percent - I would want to see the paper that produced this result - I imagine this may be one study, but until we know what was being investigated I will remain sceptical! Unfortunately many papers we can't get access to because you have to pay - the abstracts do not give the study design nor the detailed results (I don't agree with this!).
For example here are two papers that discuss this:
The first discusses gradual tapering vs abrupt cessation of HRT:
http://www.ncbi.nlm.nih.gov/pubmed/16735933That study only consisted of 91 women and did not give the figure for how many actually had their symptoms returning - the main conclusion of the paper was that there was no significant difference in outcome after 12 months between the two groups (ie gradual or abrupt).
Another study - which Panay is a co-author, is this one:
http://www.ncbi.nlm.nih.gov/pubmed/21903711Very interesting though it is, the abstract doesn't give the percentage of women who had a return of symptoms, and even if it did, also of course it is a greatly biased sample (ie women on Menopause Matters who returned a questionnaire) so is likely to vastly over-estimate the actual number in the general population of women taking and stopping HRT. In any case as far as I can make out, the survey was actually designed to find out how many women stopped taking HRT after the WHI study and subsequent advice which is a different question.
Because we will never know what would have happened if we hadn't taken HRT - to use HRT or not is a decision which needs to be taken in terms of how you feel at the time and at that stage in your life, taking into account the health benefits of taking it, improvement to well-being, and compared to the risks, and versus the negative impact of your health and well-being for the few years that you are experiencing negative symptoms, if you don't take it. For many also the health benefits will be long term.
Regarding the NICE guidelines - they are looking into whether stopping abruptly or gradual tapering gives different results re symptoms - but this will only be on the basis of current published reserach. I've been looking too and whenever there is something promising - the paper is inaccessible!
I can't remember when you started HRT lubylou but I do hope that on the whole you feel it was worth it - sorry - I'm lost as to where you are now with it, how long you took it for and how old you are!.
I've gone off on a bit of a ramble here again - oops
