Hello – The actual results are really only useful within the context of your lab’s “normal” range, and each lab is a little different.
In general, though, docs will recommend a reduction in replacement hormone if T3/T4 are too high and TSH is too low. (And hopefully, they will be considering your symptoms as well).
I would suggest asking your doctor for a hard copy of your labs, and then making sure you understand the rationale for the decrease.
