It all depends what you want to do OP.
I wish there was a way of having a permanent sticky thread here for the NICE guidelines because I keep linking to them, because they answer so many of these points- and can be printed off to take to GPs who've not bloody read them!!!!
NICE meno Guidelines
The point of the new guidelines is to bring drs (GPs ) up to speed so they aren't still basing treatment on outdated research from 10+ years ago, and also to inform us women what we can ask for.
Drs are supposed to keep up to speed and also take advantage of the training days provided by the British Menopause Society. These training days explain how they ought to treat menopause and HRT.
If your GP isn't up to speed then you have to take the bull by the horns and tell them about NICE's recommendations!
The link above is about diagnosis but you can scroll through the whole report for other aspects of treatment.
Basically - diagnosis:
If you are under 45 you are classed as having a premature menopause. This is determined by blood tests- see www.daisynetwork.org.uk for info on which tests and when.
HRT is the recommended treatment for women under 45 because you are at risk of osteoporosis and heart disease with an early menopause.
For women over 45 the advice to GPs is to treat the symptoms and not waste a) time and b) money on blood tests - just treat the women with HRT if that is what she'd like to try and there are no medical reasons why she can't have it.
If your GPs are being worse than useless, you need to be more assertive, wave the NICE stuff at them, or change GPs, or find a local NHS menopause clinic or find a private gynaecologist who will treat you with the care you deserve! Like anything, you can choose to buy health care if you come up against a brick wall in the NHS or want a 2nd opinion. You shouldn't have to of course, but if you are getting nowhere then that is an option.
Sorry for the bit of a rant but I get so fed up hearing about mostly useless GPs on the topic of meno.
