My Endo is moderately reasonable (believes that Ferritin needs to be nowhere rock-bottom, for example), but still seems rather in thrall to the almighty TSH. she has told me, as so many Endos do, that a suppressed TSH leads to a greater risk of osteoporosis and atrial fibrillation; FT4 and FT3 values in range be damned.
I will be seeing her again on Thursday and would like to challenge her on this if I can, and in a reasonable manner. Therefore I would be grateful for links to studies / literature (if they exist) showing that a suppressed TSH value with a FT4 and FT3 value within the reference range is not harmful / runs no greater risk than for the average person. I have found studies which show that a very low (>0.03) TSH is not harmful wrt osteoporosis but atrial fibrillation wasn't mentioned. These studies concluded that having TSH <0.03 wasn't great news.
In addition, does anybody know what the increased risk for both osteoporosis and AF amounts to and what the baseline risk for the general population is?
Anecdotal evidence need not apply. You may well be someone who's gone for years with a suppressed TSH and in-range everything else with no problems but that's not going to do for my purposes.
