thyroid levels to high

Ok been trying to research and figure this out my self but the more I read the more I get confused lmao. I had my thyroid removed above 4 years ago. It was three times the size it was suppose to be. Was put on synthroid125..since then md moved me up to 150. Well had to change md since then new ran test (did not get to see results) and wanted to drop it to 100...I wasn't comfortable with that so went to another he wants to raise it to 175 the test results at this doctor was:

tsh ....  43.76

free T4 ...    .833

So should the dosage increase or decrease?

With the information you've given, your dosage should increase... TSH is Thyroid Stimulating Hormone and the lower your thyroid hormone levels go, they higher TSH goes, because your pituitary gland (where the TSH comes from) is trying to get your thyroid to produce more thyroid hormones, but since you don't have a thyroid, that's not going to happen.

Your TSH is way too high and it looks like your Free T4 might be way too low, but we need the reference ranges from your lab report.  Reference ranges vary lab to lab and have to come from your own report, so if you can post that, it will be a big help.

One problem is that the biggest piece of the puzzle is missing... That's Free T3, which is the active thyroid hormone that's used by every cell of your body.  Free T4 is pretty much a storage hormone that's not used directly; it must be converted to Free T3 prior to use.  

What I do see is that your Free T4 is seems to be so low that there probably isn't much to be converted to Free T3, in which case, your dosage would need to be increased.

The biggest question, though is:  how do you feel?  Do you have symptoms of hypothyroidism?

ty... the ranges are:

tsh        0.27-4.20 mcIU/mL


T4         0.930-1.700 ng/dL


Those where the only tests done. no T3
As far as feel nothing has happened like they said. They said I would probably feel better and would lose weight. I have done the opposite. Im 50 lbs higher than I was before the thyroid was taken out and stay tired all the time. But have other health problems so other symptoms sorta hard to tell cause not sure if caused by that or other problems.
Ty for response though tells me which way I should go.

Wow - your Free T4 is actually still below the reference range and with your TSH as high as it is, you definitely need an increase in medication.

What other problems do you have?  They could be related to your thyroid condition.
