LOW TSH

How does regular t3 and t4 and irregular TSH affect pregnancy?

[Shayne Plosker, MD]

Dear gaze070 - it is hard to accurately answer your question without knowing the actual values. In general, as long as your T3 and T4 are normal, there should be no problem at all. However this is a question that is best answered by your ObGyn and/or endocrinologist who have access to your actual lab results.

I should also note that I am a 34 year old female.  My 1st child is nearly 3 years old. Conceived right away, no problems w/ preg or birth.  B/F for 15 months.  Recently miscarried @ 9 weeks (missed miscarriage) fetus was measured at only 5 weeks tho.  My thyroid went overactive post partum with my 1st child and my tsh during this 2nd pregnancy was low (.25 at times and I had hypo thyroid symptoms: cold hands/feet and low body temp between 7-9pm) we also moved during the time I miscarried so stress was a factor but I was exercising as a coping mechanism (light running).
