Hi...I have just finished reading STTM and it confirms what I have been thinking, that with low TSH, low T3 and low T4, I may have a problem with my pituitary. I also have high(ish) cortisol but that wasn't considered much of a problem after GP had spoken to the endo!
But in the book she suggests doing a five day measurement of body temperature at every 3 hours which I did (with a mercury thermometer) and also a digital thermometer but I think it's inconclusive. In the book it says if you are swinging from more than 0.1 C (or .2 - .3F) every day then you have an adrenals problems. However I swung on some days and not others eg if I take the Celcius measurements: Days 1 to 2 there was a 0.1 difference (not significant), days 2 to 3 a 0.2 swing (significant), days 3 to 4 (no swing at all) days 4 to 5 a 0.2 swing (significant). In other words half the time it was significant and half the time not. It was quite an ordeal remembering to do the measurements every three hours. I suppose I could do another batch sometime but not sure it would throw up that much additional info.
However there is 0.3 difference between the lowest average (taken on 2nd and 3rd July) and the highest taken on 30th June.
