What would cause TSH levels to fluctuate erratically but yet stay within the range? I'm on Nutri Thyroid and Thyro Complex but since Jan been on a trial of Thyroxine 50mcg. I've had an MRI scan of the pituitary and that appears to be ok, everything was signalling secondary hypothyroidism.
Last year (March) whilst on Nutri Thyroid and Thyro Complex my Free T4 came up slowly to 15 nmol, my TSH was depressed. Yet in July in that heat my Free T4 crashed to 9.3 the lowest I'd known it go. Question is why did it crash?
My Endo thought that I was on Thyroxine when I showed him my results when my Free T4 came upto 15. so he was interested when I told him i was In fact on Nutri Thyroid and Thyro complex.
I am on Sertraline. They've never tested me for antibodies plus I have psoriasis.
Anyone have any ideas?
