I was diagnosed with Graves Disease in 2012 and had Radioactive Iodine Treatment in the same year. I have since been battling to feel anywhere near to normal and have just sat down in desperation to graph my blood test results from diagnosis to now.
Interestingly my FT3 was checked regularly up until March 2013. I hadn't realised until now that this test came back below range. The results were:
TSH 0.20 (range 0.35-4.94)
FT4 16.2 (range 9-19.1)
FT3 3.04 (range 3.6-6.15)
I realise that this is only just below range however I am suffering from extreme tiredness, constantly being rundown and unwell and extreme problems with my eyes (although no apparent thyroid eye disease visually).
This low FT3 was never mentioned to me and my FT3 has not been tested since despite me having 3 more sets of bloods taken. The results from these were:
MAY 2012: TSH 0.30, FT4 15.7
NOV 2012: TSH 0.20, FT4 15.5
JAN 2014: TSH 0.37, FT4 15.9
(Ranges as above for all of these)
As my TSH is within range my doctor seems baffled by my lack of well being and has requested a full blood count and haematinics test (I do not yet have the results from these).
I am currently taking 100mcg Levothyroxine and 1600 IU Fultium D3 (Colecalciferol) per day.
Do you think that my T3 could be at all to blame for any of this and is it worth requesting for this test to be repeated.
Feeling very alone and helpless.
