peacegirl, I am also progesterone intolerant and have been advised to have a hysterectomy in the long term. At the moment, I am taking a very drastically reduced dose of (vaginal) Utrogestan under supervision with regular uterine scans and it is working extremely well at lining clearance and thinning. However, I don't want to have periods for the rest of my life so unless someone invents a modified form of Oestrogel (like DUAVEE) that stops the womb lining building up, I will have to face a hysterectomy at some point.
If you are progesterone intolerant, you can't just flick a switch and make yourself able to take progesterone.
If it hadn't been for those wretched studies, there may have been more research and development of better forms of progesterone or a less drastic medical procedure for progesterone intolerant women - something like an ablation. I feel strongly that the progesterone options for women are very poor indeed and even women who are not progesterone intolerant per se often don't feel great while taking it. It is also where all the HRT risk lies.
CLKD is so right, quality of life is vital and I think there are plenty of women who are progesterone intolerant who could safely reduce their dose and have a better quality of life.
There is only one way to find out how much progesterone you need and that is to have a uterine scan and have your lining measurement taken. No doctor can tell by talking to you from the other side of a desk. The NHS over-prescribe the progesterone part of HRT because they do not routinely offer uterine scans.
I wish there were better options available.
