My GP told me that hrt isn’t recommended for me because of diabetes. Luckily I don’t really suffer from menopause symptoms apart from one, which was the reason for the conversation but is liveable with.Shouldn't affect your BG any more than were you pre-menopausal at a time of the month (ie most of it) when your lady hormones weren't in overdrive before your period - personally mine didn't appear to go into overdrive and affect my BG anyway - but there again I was on the pill for most of those years LOL
HRT patches - cease to be effective when exposed to the sun - so if you're eg having a beach holiday somewhere lovely warm and sunny etc you'd have to stick the patch where it wouldn't be exposed to the rays - ie under your costume somewhere eg on your buttocks. When you happen to be naturist then the answer is HRT implants (the best solution even if you're not naturist) or if not, tablets.
