I had a total TT in 2011. Until last year I had left the management of my medication to my doctors. However, in the last year I have been unable to hold a dose of 100 mcg of levothyroxine without developing hypothyroid symptoms.
Therefore, when I looked back at previous results I realised that for at least 2 years this has been the case (possibly longer but attributed severe fatigue to having young children).
In December 2012 my TSH was around 2.0
In June 2013 my TSH was around 6.8 and I had many symptoms which I now realise were hypothyroid.
Then I moved to Germany and in the November 2013 test my TSH was 0.01 and I experienced a rapid heart rate.
Until March 2014 the TSH was between 0.5 and then 0.08
That was when I was pressured by a nice but totally ignorant doctor to cut my dose to 50mcg sending my TSH to 24 and giving my a bewildering array of hypothyroid symptoms.
I can't give T4 and T3 for the earlier results as I don't think they took them. The results only show the TSH in my copies and I didn't know anything about the values then.
So, in the last year I have felt that I seem to drop. It seems that times of exacerbated stress or exertion contribute.
I would appreciate any feedback. Is this a common phenomen, especially when the medication is totally replacing the thyroxine?
