I was diagnosed with hyperthyroidism some months ago.
My T4 was at 45, and my TSH had given up with a reading of <.01
I was put on carbimazole, initially 40mg/day. This got my T4 down to 11. I was told to reduce the carb to 20mg/day
But, my latest blood tests shows that my TSH is now approaching 10, whilst my my T4 remains at 11.
I was told to further reduce my carb to 10mg/day.
Is the TSH fighting with the carbimazole?
