Wow Hurdity! Thanks SO much for posting that COMPREHENSIVE article.
I have just briefly skimmed it so far.
Several things stood out to me.
They show a graph (the last one) of 3 women given a 50 patch and the individual variations of the blood levels was striking....AND, the graphs were very similar (peak-trough like) to the one I pointed you to in the link I posted. Also, the second graph there shows short time variation in one women on one patch. Maybe the top graph with the gradual decrease is actually an "average" based on the second graph?
and was made to negate the short-time variation in one woman on one patch?
Also....much lower in article, it mentions vaginal estrogen 10 tablets affect vaginal cytology but have NO SIGNIFICANT effect on urethral cytology, unlike the vaginal estrogen 25 tablets!!!!!
If I am reading this right, that means I need to take vagifem 25 which is not available in US. Whereas, the estring ring alleviates all urinary symptoms. I really am going to push for trying estring again (last time I tried it years ago I was not on hrt) to see if this will solve my issues.
Additionally, the daily graph for the gel has little peak-trough and looks like it has more potential for horizontal steady-state levels, but this comes with DAILY dosing. To be honest, I seem to feel the fluctuations I am getting with my patches and this may be a good alternative for those of us who think fluctuation in hormone level is a problem when the levels go down before changing patch.
Regarding progesterone caps.....the levels are higher and sustained longer as we have discussed before, with less side effects. I am limited on my estrogen dose because I can't seem to get my progesterone levels up, but I have not tried the vaginal administration route. I am going to discuss this with my doctor also. I think with my 100 sublingual dose, the progesterone probably rises quickly and falls, and when my blood is drawn is usually in daytime so the level is always lower (I take before bedtime). Who knows what effect we are getting from active metabolites that can't be measured though?
Luckily my lining now is the same as it was last march in thickness.
Regarding risks....my goal is to find some level that works well for a while, then I can try to decrease some to mitigate any risks involved. I am still working and as many of you, I feel I need good levels of hrt to do my job. After retirement, maybe it will be easier to lower hormone levels.
Again, thanks so much!
