It seems I might have SIFO(small intestine fungal overgrowth) which affect thyroid function as does SIBO.
Had thyroid tests on dialysis method done as normal tests vary too much. But surprise surprise lab tested them normally...how difficult it can be to read the lab referral!!!
Anyway my doctor told me in this situation I need to avoid supplementing vitamin D which is stereoidhormone ,as well as omega 3 and 6, which worsen the inflammation.
I am getting antifungal medication if I want to, he reckon my SIFO is already getting better as I have taken oregano oil and symptoms have lessened plus vit B1+B6+B12 injections have helped too.
Also my vit D is tested by different method which measure active vit D, if thats ok then I might be one of those who shouldn't supplement vit D if normal test come back low.
I am like bleh, meh, sigh.
On the positive side, all other tests show nothing to worry about, it's highly unlikely I have mitochondrial disease which is huge relief!
