I'm new here, so all help and suggestions gratefully received.
I was diagnosed as having an overactive thyroid some years ago and had the radio active treatment thus making me under active. I was started on a dose of 25mgs of Levothyroxine which has gradually been increased over the years to 50, then 75 then 100, and now 125mgs daily.
I still get my bloods checked every quarter as I remain unconvinced that I am on the right level of medication.
Can you please explain in simple terms what TSH, T3 and T4 are? My recent blood test showed:
TSH 2.58 (0.27 - 4.2)
T4 16.3 (12.0 -22.0)
