I had a baby 9 months ago and since then have felt terrible physically and mentally. Have had an awful time losing weight despite exercise and eating well, terrible constant muscular pains, depression from having no energy and low temperature. My doctor started me on T3 only almost two months ago, thinking it would help both my depression and low free t3. Currently I take 18mg's of generic cytomel (t3) a day. My labs prior to starting the t3 were
free t4 .8 (.9-1.8)
free t3 2.5 (2.3-4.2)
Anyway, last week I had my thyroid labs tested (did not take t3 the morning of testing) and TSH has gone down to 1.3, but free t4 is now lower at .7 (.9- 1.8) and free t3 is still on the lower side, exactly where it was before, at 2.5 (2.3 - 4.2).
Now my doctor wants to start me on Synthroid (t4), because if anything, my symptoms have gotten more severe, despite being on Cytomel (t3). She wants to add 50mcg of Synthroid. I agree that I need to get my free t4 up in order to feel better, but my question is, how much lower will my TSH go with the addition of 50mg of Synthroid? Shouldn't I start with 25mcg and see how my numbers look? Or will that not increase my free t4 enough to make a difference? And why has my t3 level remained the same despite being on t3 the last two months?
