I was diagnosed with an underscore thyroid about 4 years ago following a bit of a battle with my GP (another story!). However was eventually prescribed levothyroxine, test results were always a little high from my point of view and although I felt better through taking levo I thought I should feel better than I was feeling.
I've just had results back and was surprised to see how they've changed recently.
In January 18 my results were:
TSH 3.28 (0.27 - 4.2)
Ft4 18.6 (12-22.0)
Before this test I was taking alternate days of 75mcg and 50mcg of levothyroxine, GP increased to 75 mcg daily and retest in April.
Tsh 0.06 same range
Ft4 33.2 same range
Doctor recommended I reduce levo to 50mcg daily which I did and retest July.
Tsh 28.76 same range
Ft4 14.08 same range
Have I reduced too much? Am thinking parhaps going back to alternate days of 75/50 would have been better, but I've never had readings this high or as low as in April. To me this suggests was underactive, went overactive in April and now underactive again, could this be hashimotos? If it was what else should I look out for? Why would this change so drastically?
Thanks in advance.
