I am told that I have had high TSH for at least the last 5 years which has gone untreated (shown in historical blood tests). In February (3.5 months ago) my results were:
Serum TSH 47 mu/L [0.35 - 5]
Serum free T4 11.9 pmol/L [9-24]
at that time my levothyroxine was increased to 150, which I have taken for over 3 months until the most recent tests which show:
Serum TSH 0.32 mu/L [0.35 - 5]
Serum free T4 23 pmol/L [9-24]
Serum free T3 5.3 pmol/L [3.5-6.5]
My endocrinologist says that I am now slap bang in the middle of 'normal' therefore the medication is at the right level and any symptoms (still gaining weight, brain fog, fatigue etc) must be attributable to something else.
all other tests B12, iron etc are in normal parameters.
Is there something I am missing or should be looking at?
