Hi. Peeps...
Confused about recent blood tests....
My last thyroid test approx 5 months ago i forgot to take my t3 within 12 hrs of test, ( last dose was 4 pm day before am test) so theoretical it may have been lower than it should have been..
Since then i increased my T 3 slightly from 17.5 mcg daily to 20 mcg daily.
Mainly because it's easier than splitting tablets, and I now take all nhs t3, which I thought may be better than taking half an out of date tablet I would be buying online.
Im still on the same amount of levothyroxine ..at 75 mcg daily.
( actual tablets have changed tho.. Info below)
This test - I took a last dose of 5 mcg t3 at 9 pm the night before the blood test at 8.40 am .
I stopped taking all my suppliments inc all b vits a week before the test.
..
Can anyone please explain why my t4 has gone down so much now..3.9 decrease ..and my t3 almost the same as last test .??
If anything i feel like im under medicated even tho I increased my dose.. . Often tired gaining weight.. But stress eating so no surprise there.
But im not sure if i should increase meds more.. Gp and endo both say im over medicated because of the suppressed tsh.. But I am more concerned that the t3 and t 4 gap is getting bigger.. But they won't listen as it's within range. I feel something is not right.
.. I was feeling fine 5 months ago.. Had started taking estrogen pessaries ( last post has more info) but then just decided it was not worth taking as I'm just not interested in a sexual relationship, I'd only just started taking it for a month or two.. But after another attempt I just figured no point.. so I stopped. Gp said no need to worry about it and no side effects from stopping it..
Wonder could this have anything to do with my T4 level? But gp says no.. And it was such a brief amount of time.
Other possible cause..? my brand of tablets have changed slightly levothyroxine is now one 75 mcg( teva brand) tablet instead of 3x 25mcg. ( can't remember but it was some other brand)
For my T3.. I was taking half a 25mcg tyromel tablet that I bought online and one from nhs 5 mcg Morningside nhs supplied tablet 3 pm. ( 17.5mcg daily) Then i switched to ( 2x 5mcg Morningside twice daily = 20 mcg daily ) all nhs prescribed tablets.. I'm wondering if it could be to do with absorbing the tablets..
Im always worried about the other tests that are high.. doctors never seem to be able to explain that.
