Recent lab results..can anyone help?

[tinapel]

I'm a 50 year old woman who had my thyroid removed in 2003.  I started
with Synthroid then switched to Nature throid. Current dose = 90mg which I
split and take twice a day.  I am also pre-menopausal.  Here are my
recent lab results:
TSH = 0.62    range - 0.40 - 4.550
FT4 = 0.8      range - 0.8 - 1.8
FT3 = 263     range - 230 - 420
I have been feeling tired lately, bloated, loss of appetite, low to
non-existing sex drive. I also go to the gym 4 days a week and have gained 5 lbs without changing my diet.
Does anyone have any ideas as to why I'm tired with a TSH of 0.62?
Any suggestions would be appreciated.  I see my endo next week and I
don't think he will give me an increase based on TSH.

There is no excuse for a doctor who ignores symptoms.  After all, what good are "normal" labs if you still don't feel well?  Best of luck in convincing him, but if you can't, find yourself another doctor so you don't continue to suffer even longer.

Thanks for the information.  Just as I suspected, but I sure hope that I can convince my doctor to give me an increase.  I've been feeling like this way too long.

Your FT4 is way too low, and so is your FT3.  TSH is a pituitary hormone and a very poor indicator of actual thyroid levels.  You definitely need an increase, which you know based on your symptoms.  Meds containing T3, like NT, will suppress your TSH, often to the point where it has to be ignored.  Your doctor should be adjusting meds based on FT3 and FT4 levels.  If he's not, you need to either educate him or find a new doctor.
