Well, completely unexpectedly today I got blood test results showing I am 'subclinical hypothyroid', according to "Thyroid Disease" by Mark Vanderpump. Apparently, according to him, having a high TSH with a low T4 puts me in that category.
My actual results were TSH 5.2 (highlighted as high) and my free T4 was 10. This is normal, but on the low side as the bottom of the range is 9, so not well into normal by any means.
The GP I saw - not my own - was of the opinion, I think, that if I was showing symptoms I might want to treat it, although she was at great pains to point out that "they wouldn't normally consider this result as needing treatment". She said I should discuss it with my GP, who will LOVE this, since he only gave me the test because I asked for it, and we'd had a big fight over other testing, so he was humouring me.
My confusion is this. I have a rare neurological condition, Trigeminal Neuralgia, incurable and degenerative. I felt that it might be B12 deficiency related, had another big fight over testing for that, and to cut a long story short, ended up being treated for B12 deficiency, even although I didn't merit it, as far as the NHS was concerned. Lo and behold, my TN has indeed responded, spectacularly, to B12 treatments. Since then I have been trying to make sense of this B12 connection, as I feel sure there is one, of an autoimmune nature, if I could just get to the bottom of it. I have explored coeliac and other malabsorption issues, but so far they have been a dead end.
So I'm wondering, does B12 and thyroid have a connection? If so, what is it? I have had gastric problems for upwards of fifteen years, gallstones and then this, the TN. I feel sure they are all part of a pattern. I did NOT expect thyroid to play a role in it, but it looks highly suspicious that it might.
Before I tackle my disbelieving doctor yet again, does anyone have any connections to offer for B12 and thyroid and how it may fit with gastric problems or, indeed, neurological problems? Any connections most gratefully accepted, especially if they are from reputable, i.e. scientifically sound, sources!
