Good day - hope you can provide some advice/insight around thyroid function. I have been diagnosed with an anxiety disorder 3 yrs ago as I was/and still am experiencing intense physical anxiety. The immediate thought when it started occurring was that it may be my thyroid as my mother and 2 of her siblings suffer from over active thyroids. I have done 3 thyroid function tests in the past 2 years which all came back normal (have been on a number of SSRI's, benzo's and beta blockers). The last function test I did a week ago as part of some other blood tests showed that my thyroid is overactive (based on TSH and Free T4).

My question is if it is possible to suffer from an overactive thyroid even when the function test shows a normal results? I have used Proprananlol and SSRI's when other tests were done but not for the last one, but as far as I understand Beta Blockers cannot impact on the test results. (I do not appear to have any physical symptoms of Graves disease, I only have severe physical anxiety symptoms i.e. sweaty hands, insomnia, nervousness, hot flushes, inability to relax).

I can only get to see an Endo in the next 4 weeks, are there any other tests I need to ask for in the meantime that my GP can arrange to confirm that I definitely have a Thyroid problem. I am hoping that my anxiety condition over the past few years can be attributed to my thyroid.

Kind regards
