A couple of weeks ago I posted with a query about whether or not to take HRT, as my GP wants me to - grateful for the responses to that and I'm been mulling over the best way forward.
While doing so I came across test results for FISH and LH, taken at the same time as the tests that led to my hypo diagnosis on 31 Aug 2017. Both FSH and LH are very very low, below the bottom of their respective ranges:
49.5 u/L (range 1.7 U/L upwards, with >35 U/L being perimenopausal)
25.2 u/L (range 1.0 U/L upwards, with perimenopausal being 7.7-58.5 U/L)
Those are not typos by the way; my results are in u/L ie milli-units whereas the ranges are in U/L ie units. So my results are very low.
Not sure therefore why my GP thinks I'm menopausal, but she seems to want to attribute my symptoms to menpause rather than thryoid. I don't know what those FSH and LH results do indicate though. I googled them, and found that apparently low FSH and LH can be caused by hypothyroidism or alternatively by dysfunction in the hypothalamus or pituitary. So the right course of action might be continuing to sort my thyroid - but if it's a hypothalamus or pituitary problem, I don't know what if anything needs to be done. Either way, the GP would need to have a very good answer to convince me to take HRT!
Can anyone explain these results or give any advice please? (I have the mirena coil fitted so don't know is what my cycle is doing as not bleeding at all now.)
For completeness, thyroid results 31 Aug 2017:
TSH 6.89 (0.27-4.2)
FT4 11.1 (12.0-22.0)
After these started on 25mcg levo.
Results 30 Oct 2017:
TSH 3.58 (0.27-4.2)
FT4 14.3 (12.0-22.0)
Dose increased to 50mcg after these.
Now awaiting results of thyroid bloods taken a few days ago, then will talk to GP again.
