In another thread about metformin I started, I had some helpful suggestions to look into thyroid.
At the time, I'd had two prior tests during the last 6 months, and was advised here on Excelmale things were worse than I thought. Looking into things away from the standard clinical approach, I came to agree.
I had:
Jan '19
TSH H 6.21 0.27 - 4.20 mIU/L
Free T4 17.80 12.0 - 22.0 pmol/L
March '19
TSH H 5.27 0.27 - 4.20 mIU/L
Free T4 13.80 12.0 - 22.0 pmol/L
There were cries of 'Hashimotos!'. I duly went off and did a more in depth test. Unfortunately I chose one without the RT3 test, because it was about 4x cheaper. I was mostly interested in antibodies in the short term.
TSH 3.46 mIU/L (Range: 0.27 - 4.2)
Free T3 3.96 pmol/L (Range: 3.1 - 6.8)
Free Thyroxine 17.100 pmol/L (Range: 12 - 22)
Thyroglobulin Antibodies X 491.000 kU/L (Range: < 115)
Thyroid Peroxidase Antibodies <9.0 kIU/L (Range: < 34)
As you can see, if you believe the standard stuff, everything is 'normal' now, thyroid hormones wise. But as many here will agree, 3.46 TSH is still not normal, and I at the lower end of FT3, and that's without even checking for RT3. Besides I started metformin (off label) two weeks ago, and I understand that its reductive effect on TSH can be visible fairly early on. I also understand, and if I'm honest I think most people don't, there is no evidence metformin's impact on TSH translates to a lowering of T4 and T3.
To my surprise, looking around a the standard diagnosis checklist for hashimotos, I cannot decide if that's a diagnosis which applies to me. You can guess probably that I think it does. What do you think? High TG and low TPO?
