You may have seen my last post where I told you of the situation where Dr T instructed me to withdraw from levothyroxine for 4 weeks and get my bloods tested. The main reason for this is because my TsH remained normal when I was diagnosed 2 years ago, despite brutally low free thyroid hormone levels.
3 weeks into withdrawing from levothyroxine I experienced a return in my symptoms including crippling tiredness.
Here are the results of my bloods:
T4 - 7.9 (7.9-20)
T3 - 4.8 (3.8-6)
TSH- 4.25 (0.34-6)
Other bloods I requested
Ferritin 28 (11-370)
B12- 525 (120-625)
Folate - 15.9 (<3 suggests deficiency)
Vit D - 56 (<50 suggests deficiency)
So clearly my TSH has responded and come up very quickly from it being previously suppressed at 0.07 all the time or thereabouts. My t4 was previously always in the top of the range and now is basically at the bottom. T3 is somewhat normal. However this was only after 4 weeks and presumably I would still have had Levo in my system. I'm sure after another 2-3 weeks my TSH would continue to rise and free thyroid hormones continue to fall. Is it safe to say I definitely am under active and do you think Dr Toft will agree and that I should be taking meds? I am not seeing him until 23rd December but he did instruct me to take my meds between this blood test and then.
I am concerned about my ferritin as it is very low (although not low enough to be under normal range) although seen people on here advocating for a level above 70. What is the best way I can get my ferritin levels up? Presumably this is also contributing to my tiredness. I don't eat meat or fish so can't really get it from red meat etc. I'm more thinking on the lines of a good supplement if anyone has any recommendations.
Looking forward to reading your responses- I swear this forum keeps me alive and sane !!
