I'll make a thread on this. Thyroid hormones are going towards hyperthyroidism. TSH = 0.46 ( 0,3-4,2 my former GP used 0,4 – 4,0 mU/l ) fT4 = 24 ( 12-22 my former GP used 8 – 26 pmol/l ) so imho it is still within range. GP has tested for TSi, that was oke, which I am happy about. But still I think there is something going on there. because there is a trend getting TSH lower and fT4 higher. The strange thing is, when my health was going south some years ago, I thought that I might be going toward hypothyroid. Mainly because of the eyebrow-thing that I read about. Some time ago my eldest sister gave me a childhood-picture of me ( very nice to see myself as being a sixyear-old, with red bows in her tails, a freckly face and her eyes still very squint-eyed ) but a look at that pic showed the eyebrowthing...and yeah, I've always been kinda slow... so now I wonder. I don't know anything about the whole thyroid thing, those articles that @pattismith posts are way beyond my head and need my head now for making wise decisions about a bankloan ( which I get ) something in me tells me that I may have a problem converting T4 into T3. Am I right in thinking that when that is the case, THS and fT4 go up while the body is not getting enough because of the conversion-thing? so the blood looks like hyperthyroid, while the body is hypothyroid??? the other thing that springs to mind is the fact that my parents have overloaded my body with fluoride as a child. And fluoride applied by a dentist was one of the things that have pushed me over the edge some years ago.
