Dr. Lupo,
I was diagnosed with hashimato's hypothryroiditis a year and a half ago. I have been taking 75 mcg of Synthroid with an extra half pill a week, which has not changed since June. The only other thing I regularly take is birth control pills. My recent test results have me confused.
Sept.
TSH 2.54 (0.38-4.70)
Free T4 0.74 (0.59-1.17)
Free T3 4.21 (1.8-4.2)
Nov.
TSH 3.63 (0.38-4.70)
Free T4 0.79 (0.59-1.17)
Free T3 4.27 (1.8-4.2)
My doctor is concerned that the Free T3 is high and is afraid I could be getting too much Synthroid. I am concerned with the TSH going higher and have started to feel more of the hypothyroid symptoms (dry skin, tired, hair falling out). So part of my question is related to what could cause these odd test results? Also which test is a better indicator of thyroid function? Is a slightly high Free T3 bad?
Any information you could give me would be helpful. I have not been able to get these questions answered at this point.
Thanks.
