There is so much incorrect information out there that it can be a bit of a minefield trying to find and navigate the route. The complication I find being in perimenopause is that my cycle is still present and causing all sorts of symptoms which are not predictable from day to day nevermind month to month.
The UK seems to prescribe on symptoms rather than blood results in the most case and to be honest my experience of both is that the symptoms are telling the story just as well as bloods.
So, oestrogen during perimenopause doesn't just "decline" as a lot of people believe, indeed it goes a bit mad and spikes and dips unpredictably.
Its for this reason that I fail to understand how the cream based versions from private clinics can be any better than the mainstream solutions, except of course that they cost a lot more and are not licensed for use, especially to protect the endometrium.
Given the perimenopause situation, the two main approaches I have seen are
- Supplement the oestrogen with a low dose of 17beta estradiol which is the bio/body identical oestrogen (not a horse in sight!) to try and even out the spikes a bit. The really popular solution for this seems to be Oestrogel, a topical gel where you can tailor the dosage a bit to suit yourself. However it is not recommended to keep changing the dose too frequently as it simply serves to confuse the issue more.
- Take high levels of oestrogen to override your normal cycle. This I have only read about and haven't tried myself (I did option 1) so perhaps someone with more experience on this could pop along and help out.
In both of these situations, if you still have a uterus, you must oppose the oestrogen with progesterone in order to prevent the endometrium proliferating too far and adding unnecessary risks. The NICE guidelines, as I recall, say something along the lines of 200mg progesterone for a minimum of 12 days. As with the oestrogen, micronised progesterone (Utrogestan) is a bio/body identical hormone and not as with progestins synthetic.
There is, I have found a lot of trial and error, frustration and exasperation in finding the right dose but I can also say that it is absolutely worth it because I have rediscovered the woman who seems to have vacated the premises when my hormones started going mad. Having been on the journey for about 3 years prior to HRT then taking HRT I would have taken HRT earlier.
Hope this helps.
