Hi. I'm a 47 year old male in the UK: I started self-medicating with WP Thyroid 16 months ago because of hypo symptoms -lack of energy, feeling cold, constipation, brain fog and poor memory. My last test was 18 months before I started self-medicating:
Serum T4 level 12.4 pmol/L (12 - 22)
Serum TSH level 2.87 mU/L (0.3 - 4.2)
These two were the only tests in the thyroid section of a wider panel of blood tests ordered by my gp when I presented with lack of energy - he failed to diagnose anything and I didn't bother approaching him until now about possible thyroid medication as the results were "within range".
I increased the dose of NDT to 4.5 grains over 7 months and have been on that dose since - the only real symptom changes I've noticed are temperature (don't feel cold anymore) and brain fog (has lifted a bit).
Due to cost I recently approached my gp for a prescription; after the initial consultation (with blood draw, test results below) I was quite hopeful but on my return he said he could only prescribe levo (obviously not true as other GPs prescribe NDT). After indicated my unhappiness at this he offered me an appointment with an endo which I accepted.
Blood drawn at 10.07 am, hadn't eaten for 10 hours but had taken usual 4.5 grains WP Thyroid on morning of test (plenty of brain fog left obviously) :
Serum T4 - 22.5 (12 - 22)
Serum TSH - 0.01 (0.3 - 4.2)
Serum free T3 - 14.0 (3.1 - 6.8)
Se thyroid peroxidase Ab conc - 7 (< 34)
I have been promised an endo appointment (apparently will be some time due to waiting list) and have been told to get blood drawn a week before. What dosage should I reduce to?
Should I ask for a Thyroglobulin antibodies test or any other test?
Should I have tried levo before NDT?
On doses over 4.5 grains I got too warm (have little energy on any dose).
All advice much appreciated.
