Pregnant with no thyroid!

[Trishlk]

I just found out I am pregnant! I am so excited! I am worried though because I just had my thyroid removed in July and am still getting my meds regulated. I am on 125 synthroid and last numbers were too low TSH was 0.024 and that was when I was on 137.
Will I need to get my dose changed higher or lower with pregnancy? I am calling my doctor Monday, or should I call the exchange this weekend? I don't want another miscarriage so I am worried! I had one back in June before my surgery.
What do you all think?

Hi,

since my last post in 2009 I have had a second child with a non-performing thyroid.

My baby is now 3 months old and seems perfect.

I increased my thryoid meds for the first 6 months of the pregnancy and tested every 4 weeks.  I ended up increasing my meds by about 50% overall.  We tested Ft3 and FT4 rather than TSH and adjusted medications based on keeping FT3 and FT4 in the upper 1/3 of the reference ranges.

Hello:) I was wondering how your pregnancy went. I was born without a thyroid and had a miscarriage in march. I believe I am now pregnant and I thought I was alone on this thyroid problem. This really gives me hope:)

Hi

low tsh during pregnancy, particularly early pregnancy is totally normal. Some of the pregnancy hormones affect the test results.  Better tsh is low than high also.  Your dr needs to monitor ft3 and 4 as well as TSH. FT3 and FT4 need to be kept in the upper end of the reference range. Normal to test and adjust monthly during pregnancy, with dose increasing anywhere from 20 - 50+%.

monitoring just tsh during pregnancy is not ok. Insist on the others too.

I think your med should be maintained as is, but test ft3 and 4. ig all ok, test again in 4 weeks.

usual dose increase in pregnancy is 25 mcg/adjustment.  

Congratulations!
