Am I overactive

[Ricky_]

Hi I'm new here. A quite story. In 1995 my tsh was1.74 and ft4 14.6.

Since it went overactive ,treat with radioactive iodine in 2001, now my reading are tsh 0.01 and ft4 19.5. Am I overactive! Doc thinks not. Any help appreciated.

Welcome to the forum, Ricky_.

If your FT4 19.5 is within the lab ref range you are not over medicated. The lab ref range is the figures in brackets after your results.

Hi, thanks for getting back, does the low tsh not come into the equation.

Ricky_,

No, low TSH just means your pituitary gland has detected sufficient circulating T4 and T3. It is FT4 and/or FT3 being over range which means you are over medicated.

Thanks for your help, let's hope it stays that way.

Despite the lack of reference ranges, the 1995 results you quote do not show evidence of you being hyperthyroid at that time. What changed between 1995 and 2001?

I was coming to the end of a 23 year army career in 2001, my sister died suddenly towards the end of 2000, it was then I noticed changes (with hindsight), but was not diagnosed by doc until late October, by this time my ft4 was 88.
