@Jonathan Edwards We have 'met' last year on a different part of the forum last year where I was contemplating whether I really did have ME due to the fact that I had Hashimoto's diagnosed some years beforehand. At the moment I do think in my case that there are distinctions, especially as my symptoms worsened long term following whooping cough, as they can do with ME. I know this is an old thread however, I do think this is an interesting issue.....
Over the past few years I have gone on both ME and thyroid forums trying to unpick my own problem and wondering exactly what is what. It's not as simple as you seem to say.
A couple of years back I had a conversation on the phone with a well known ME scientist (I don't want to name the person as it was only verbal, and I cannot provide a link). I asked them the question re the thyroid and they had seen many ME patients and said that the thyroid was dysfunctional in a high proportion (it was over 70% quoted). The scientist said though, that 'however we don't know if the problem is upstream or downstream' and I guess that's still the issue. Maybe ME itself creates thyroid dysfunction rather than the other way round, so it's understandable that some people would then think of causation.
Also I have noted quite a number of people on thyroid forums who DO seem to have ME type symptoms. It's quite possible that they do in fact have ME rather than thyroid conditions, or in fact BOTH like I have but endocrinologists are generally held in some contempt by the forums for the rigid attitudes encountered in diagnosis and help. Women (and it's usually women.....) being treated by male endos (it's usually male) suggesting that their problems are chronic fatigue syndrome or depression is what is often encountered. The thyroid world seems to be as hidebound as the CFS world...
One thing I have taken in over the last few years is the general upset in the thyroid world over modern diagnosis using TSH only. In my own case I was diagnosed nearly 20 years ago, when 'borderline' cases were treated, but I wonder now if I would have been treated with T4 quite so readily as my TSH 'only' was around 4 or 5. I gather that the rules now suggest to some GPs that they should not treat until the TSH reaches 10, even though the ranges vary across the world, and are set lower in the US. NICE guidelines do suggest that doctors should also take into account symptoms if TSH is over 4.5 but I gather that many GPs do not follow this. My own GP told me that I knew more about the thyroid than she did, and that's certainly one issue encountered by others!
In addition, FT3 testing is now not done routinely in labs, and it's hard to get done on the NHS at all except under and endocrinologist, so there are a significant proportion of people whose TSH is normal and yet their FT3 is low and it's likely that sufficient conversion from FT4 is not happening (if FT4 is high for example). In my case after some years of T4 only treatment this is exactly what was happening, and yet I had to pay privately for the FT3 test!
By this time I had the ME diagnosis and hoped that changing my thyroid meds to T3 only would then supply the 'answer'. I have been on T3 only for 2 yrs now, luckily for me via an endocrinologist. While I am on the whole better than I was on T4 only, it hasn't proved to be 'the answer' sadly. I have tried going back to T4 mixed with T3 but feel quite ill now on T4 at all, and as the hair on my legs stopped growing,and I had more hairloss from my head, I backed off but am thinking of trying NDT in the Spring which is disapproved of by the NHS so will have to go privately.
