0.419 TSH on Synthroid 100 mcg - ??

Any advice is appreciated. I was diagnosed w Graves in 04, was on meds & after my 1st child leveled out to normal. After my 2nd child I was diagnosed with hypo & have been on Synthroid (branded) ever since. I am currently on 100 mcg dose & have felt terrible lately. I should add that I am currently training for a marathon & have gained weight. I am constantly exhausted which I dont think is due to the training. I called my endo & she tested my TSH which came back as 0.419. She did not test my T3 or T4. She recommended lowering my dose to 88 mcg.

Any advice out there? I am so tired & sick of gaining weight. I am very very frustrated. thanks!!

It might be a good idea to ask endo to test your T3. My T4 came back normal, and I still feel bad; I am going back on the advise of my endo to have my T3 tested. I hope this will give me some answers. Maybe you can ask for this to be done for you. Good Luck.

Your doctor should not be looking at TSH (pituitary hormone) to adjust your meds.
This applies even more so to us Graves' patients since our antibodies affect TSH levels.

Please ask your doctor to test your actual thyroid hormone levels - FreeT4 (T4 or thyroxine, free, direct) and FreeT3 (tri-iodothyronine, free, serum)

Both levels should be above least in the upper third of the range if not towards the top end.
