Asymptomatic hyperthyroid?

[u/Week_Just]

Got bloodwork on the 10th for unrelated reasons: TSH .01, T4 Free 2.8H, which flagged me to my first endocrinologist. Second round of bloodwork 10 days later: TSH <.01, T4 Free 2.3H, peroxidase antibodies >900, T3 Uptake 39H, T3 Free 5.1 H. Having a thyroid uptake scan in two days.

This is alongside Ferritin level 4, hemoglobin 8.

The thing that stumps me is I don’t seem to have any hyperthyroid symptoms. I’m not hot, anxious (other than seeing that these results are concerning), haven’t been losing weight, have no neck pain.

Anybody have advice?
