Hi Joesmum

from me too.
I agree that if you have had surgical menopause and you have found a treatment that works ie the implants then do continue with this as you are still young.
Notwithstanding other members' experiences about how they feel on different oestrogen levels - from what I've read, research shows that there are no absolute oestrogen levels which are an indicator of when a women will or will not experience symptoms such as flushes and sweats and as pointed out it is often the drop in oestrogen that triggers these symptoms - but seemingly not during the normal menstrual cycle otherwise we would all have them all our lives!
As you have had a hysterectomy and don't need to worry about progestogen then why not have the level you feel good at. I can see your point about maybe trying to reduce - but you are still young at 51 - I haven't even started peri-menopause then.
For the rest of us - while many of us might feel even better on higher doses of oestrogen, if we have our uterus, we have to take progesterone and this is usually the limiting factor for our oestrogen dose! Also as a complete contrast my levels when last measured were something like 212 pmol/l - so as yours are (and I am on a 50 mcg patch) - but I suffer no symptoms of flushes and sweats nor joint aches or low mood so this is fine as a post-menopausal oestrogen level for me! I am not raring to go with enthusiasm all the time and if my levels were 300 pmol/l + then maybe I would be - but I don't want to take progesterone more often nor have a heavier bleed.
I did read that HRT doses were designed to give an average oestrogen level across the whole menstrual cycle of somewhere in the 300's (in pmol/l). I'm not sure what would be the consequences ( in terms of health, cancer risk etc) to have levels at the ovulatory peak for the rest of your life - but there are no data on this as far as I know!
The ref ranges for estradiol are here:
70-510 females: early fol. phase (day 5)
390-1480 females: preovulatory peak
70-600 females: luteal phase
< 130 post-menopausal
For most of us it's a compromise between eliminating symptoms and taking progesterone/bleeding - but for you - I would make the most of it and go for the implant. The other alternative is to slowly increase your patch - so go to 100 mcg and see how you feel and take it from there. You might find that you feel good on lower levels than 800? 50 mcg is very low following on from an implant!!
