I have had UT for 10 years diagnosed post partum. Currently taking levothyroxine 100mcg which has increased from 25mcg over the years. My last blood test was via the GP annual review which came back "normal". They only tested TSH and FT4. I asked for a referral as I still have symptoms I believe attributed to UT. I cannot (despite trying everything) lose any weight I am terribly constipated and have dizziness and a constant "thick head". The doctor said basically move more eat less ( i couldn't actually eat much less) and he wasn't prepared to do anything as TSH was fine.
Having suffered for 10 years with this attitude I took it on myself to got and see a nutritionist who recommended I got more detailed tests so i went to a lab and paid for some. They have come back as follows:
Anti-thyroglobulin abs <40 (0-40)
Anti thyroperoxidase as 351 (0-35)
FT4 15 (9-22)
FT3 3.51 (2.63-5.70)
TSH 0.73 (0.35 -4.94)
Iodine 63 (100-199)
Iodine/ Creatinine ratio 0.13 mmol of iodine per mole of creatinine (ref interval 0.12 -0.42)
Does this mean I now have an auto immune disease despite taking thyroxine? Is diet the only way to stop having this? Should I be asking for vitamin/ mineral testing also?
Thanks for any help and advice I have read lots on here and its all so useful.
