What should be my TSH level- pregnant after Thyroidectomy.

[troy95]

Hi,

I am on thyroid medication for the last 3 yrs after I had my thyroid removed completely due to a malignant tumor. My thyroid levels are maintained at a below than normal range all these years. I am in my second trimester of preganancy. Immediately after I concieved my TSH shooted up to 20.8 and my endocrinologist increased my doses and brought it back to 1.25 and asked me to continue the same level of medication. After testing it every two weeks my current TSH level is at .23, which I feel is too low being pregnant. My endo has not made any adjustments in my medications. Please advice if a TSH level of .23 is ok or should I be atleast .50 and above, so that my baby will be fine. I am having this baby after a very long wait, and I want everything to go fine.

I think doctors wants TSH 0,3 - 2 in pregnancy, but after a malignant tumor and no thyroid, usually TSH should be suppressed. TSH is released by the pitutary to tell your thyroid (which you do not have) to make these hormones, so what is really important is your free T4 and free T3, those are the levels.They should be in the hyperside during pregnancy ( in the upper 1/2 to 1/3 of your lab ranges ).
