Hi Mommarv
from me too and so very sorry to hear about your daughter's cancer and prognosis. No wonder you are exhausted and of course you want to be as well as you possibly can.
With all the stress you have been under it's no wonder you have put on weight - and you mention the increased cancer risk. Your GP will know you well I presume so in your position I would really ask for help and referral re reducing your weight because as you say you want to be in the best possible health for your granddaughter. Getting on the road to weight loss will also help you feel better and reduce the intensity of your flushes as well as reducing your cancer risk. What a lot to ask of someone having to cope with what you are having to do? Your doctor should have no hesitation in giving you every possible help so that you won't be at greater risk yourself.
Re HRT - depending on where you are in menopause you could be offered continuous combined (no-bleed) or a cyclical type where you get a bleed every 4 weeks - this latter is if you are not post-menopause and have had a period within the last 12 months. If you are very close to menopause - one or two periods only in past year, in view of your age then you could be put on the continuous combined type straight away.
Have a look at the Treatments tab above and HRT preparations, at the different types. There are tablets, patches and gel (with separate progesterone) so it's a matter of personal preference. Do you know if your doc is sympathetic about menopause and HRT? Sometimes the progestogen in the HRT causes pmt problems for some women so sometimes it's best to start with a cyclical type first anyway to get used to HRT and then change after 3 months if it doesn't suit you.
Do read up all you can before tomorrow and if you want to know anything else about it please do ask.
