Had my thyroid removed in 2010 with no problems thereafter. For the past two years my levothyroxine dosage level had been 87.5 gms (funny level but it worked well for me) and TSH level was OK at 0.57(mUI/L) in January this year.
Moved house and first test with new GP was May result TSH (XaELV) was 0.09 mu/L [0.35 - 4.94]
Serum free T4 level (XaERr) 15.8 pmol/L [9.0 - 19.0]'
Next test July - TSH (XaELV) was 0.03 mu/L [0.35 - 4.94] Serum free T4 level (XaERr) 16.4 pmol/L [9.0 - 19.0]
Levothyroxene changed to 100mg. Didn't make any different to the tiredness. itchy skin etc.
Latest Test November 7th - TSH (XaELV) was 0.06 mu/L [0.35 - 4.94] Serum free T4 level (XaERr) 15.6 pmol/L [9.0 - 19.0]
Any advice as to what is going on here? Do I need more or less thyroxene or something else?
