I was diagnosed with an under active thyroid about 2 years ago, after a prolonged spell of exhaustion and regular illness. I'm on 25mg of Levothyroxine a day. Since then I've continued to be constantly tired, but the worst bit is that I seem to catch every bug going. I'm being floored by flu-like symptoms at least once every 4-6 weeks, for at least a week at a time, even through the summer. My vitamin B and D are a bit low, despite taking multi-vitamins, but not too drastic. My GP thinks everything is fine and I've just been a bit unlucky with bugs.
I've tried going gluten-free, but that didn't make any difference (and I've been tested for coeliac, which came back negative). I've tried to get fitter - but the in-between-bouts-of-flu spells aren't long enough, and I faint quite often during or after rigorous exercise. Saying that, I am still trying to do swim or walk a few times a week. I've tried eating super healthy. I rarely go out, or do anything, as I just want to sleep.
Any ideas? I want my life back.
My last results were:
TSH = 3.2
Free T4 = 17
Vitamin B12 = 287 (up from 194 at previous)
Serum folate = 5.4
Vitamin D = 53
