Re: Hashi's and new test results.
I take natural thyroid. My TSH hasn't been higher than .02 in nearly 9 years, but that's fine with my MD who understands the T3 component in the med suppresses TSH. TSH has no practical purpose when the thyroid feedback loop gets interrupted by exogenous thyroid supplementation, particularly so when T3 is one of those exogenous hormones.
If you feel good, there's no reason you can't continue with the same dose. Don't increase just to play the numbers game. My own FT levels aren't what would be considered optimal for the average thyroid patient, but I feel good and don't plan to push the issue for a dose increase unless I start symptomatically backsliding.
I hope you won't have to fight about that TSH level. Good luck!
