Hi everyone. I posted recently after a blood test indicated a low tsh at 0.2. but T3 and T4 within range. I had never had a thyroid test or any issues that I thought were thyroid related up until that point and am not on medication. Another blood test again showed T3 and T4 within range but TSH down to 0.07
I was referred to an endocrinologist who repeated the tests and antibodies and all were ok except the TSH has now dropped to 0.06.
He has now suggested we wait 4 weeks and try again as it could be silent thyroiditis.
What else could be causing this? Is it potentially a pituitary gland problem? Would I know about it if the had a non-thyroidal illness?
Any help would be warmly welcomed.
