Hi Shannonplussed
As you say the best person to interpet and advise on this is your doctor and then referral to a gynaecologist.
However just a few observations.
Firstly, if you started HRT only 5 months after stopping the pill then you don't know if you are menopause yet. This is defined as 12 months without a natural period (ie not on HRT, mini pill, COP, or Mirena coil). You only went5 months before starting HRT? Given your age then you may still be peri-menopausal (FSH tests cannot predict whether you are post-menopausal as they can go into post-menopausal range even in peri-menopause.)
"A normal [
FSH] level does not exclude early menopausal transition and a raised level does not exclude continuing ovarian function."
https://www.menopausematters.co.uk/diagnose.phpThat being the case then you might expect some thickening of the uterus lining and even bleeding (beyond the 6 months settling in time) if ovulation takes place.
Secondly, as I understand it, a slight thickening of the uterus lining per se is not necessarily a cause for concern especially when taking HRT. You bleeding could have been an actual period - but not as heavy as you would expect because you are taking progesterone continuously.
Hyperplasia doesn't develop from too much oestrogen
per se - but the ration of oestrogen to progesterone is too high. You can take as much oestrogen as you feel you need to feel well, provided that the amount of progesterone is sufficient to keep the lining thin.
Obviously the lesions will need checking but in the absence of bleeding are far less of a worry I would say. When I had unusual structure identified on a scan I had a hysteroscopy and biopsy - because I was well post-meno and had had some abnormal spotting or bleeding - which should always be investigated.
As you say - if it is thickened there could be all sorts of reasons eg if you are still fertile but it can be thinned as you say with a higher dose of progesterone if it continues to remain thick - or as advised by your doc.
I don't follow your argument about the body needing to hold onto fat stores in order to make oestrogen? I don't think it works like that. Storage of fat is under metabolic control and dependent on your diet and exercise amongst other things. If you have excess fat then the fat cells can make estrone from androgens which can then be converted to estradiol elsewhere in the body, so I understand, irrespective of exogenous oestrogens. In order to reduce the "fatty stores" you need to increase exercise and change your diet - (unless you have a thyroid problem) - and sometimes that doesn't even work we find!
Just a few random observations - hope you get on Ok at your appointment and all is well!
