So...last year I went to the doctors for extreme tiredness and had the standard blood tests done. The results came back with slightly low tsh and slightly lowT4 (I think). Usefully I didn't keep a copy of my results.
I remember my doctor saying the results were unexpected because my low tsh wouldn't normally correspond with the low t4. He said I might be starting with under active thyroid and to go back in a few months.
Obviously I didn't and a year later I went back with heavy periods and the same symptoms. He said again last time I was borderline under and sent me for more tests.
I've just called for the results and I have a TSH of 0.38 but the receptionist couldn't find any other results. She said it's come back in the normal range.
Again this would seem to indicate an overactive thyroid if anything wouldn't it?
Is it possible to have an under active thyroid with such a low Tsh?
Is there any point pursuing this with the doctors?
