Hello, folks --
Would like some feedback on my lab results, as I was only recently diagnosed as hypothyroid. I'm a 38 year-old man. When I was diagnosed about six weeks ago, my labs were as follows:
TSH: 0.745 (range: 0.270 - 4.200)
FT4: 0.92 (range: 0.93 - 1.70)
My doctor prescribed 75 mcg of Synthroid, which I have been taking for about six weeks. I feel significantly better than I did -- less cold, less sore, I can actually get out of bed in the morning, and I can work out a little. But, I feel like a lot of the symptoms are still present, just decreased.
I now have a new set of labs from a couple days ago. My TSH decreased and my FT4 increased. By the way, no, my doctor didn't run any other thyroid tests.
TSH: 0.351 (range: 0.270 - 4.200)
FT4: 1.19 (range: 0.93 - 1.70)
My doctor reluctantly, at my request, increased my Synthroid to 88 mcg, but said he was concerned about my TSH level getting too low.
Does this all seem correct to you thyroid gurus out there? I realize my TSH is on the low end, but it seems strange that my FT4 wouldn't increase more -- almost like I'm both marginally hypo and marginally hyper. Should I even be concerned about TSH if T4 could still stand some improvement? Any advice? I am very interested in any feedback or opinions on what the issue might be, or how others in a similar situation have been treated successfully.
Thanks in advance.
