Any have a low TSH but normal T4, T3?

Question

Hyperthyroidism runs in my family. I'm 16 weeks pregnant and my TSH is super low but my other levels are normal. I'm being referred to endocrinology and of course I'm super paranoid. Supposively pregnancy can throw your thyroid our of wack. Anyone have experience with this? And what did it mean?
They told me not to be concerned about my pregnancy but of course I am!

Answer

I’ve had thyroid problems for 8 years, my TSH is always off by a lot, either too high or too low. I’ve had two completely healthy pregnancies in that 8 years, if you do need meds just make sure you take them everyday as directed and baby will be all good :)

Answer

So, I have hypothyroidism, so the opposite of you. But my T4 and T3 have been good my entire pregnancy, but my TSH has been really high so they’ve just upped my dose every time I get bloodwork done. I usually get bloodwork done every 4-6 weeks.

Hi I know this post was long time ago.. I hope I'll get a few sec of your time to read and respond.. but I'm having the same experience right now on your lab values of low tsh and normal ft4 and ft4. Still waiting for my doctor appointment.. Did they gave you medication? Or theres no need? And how was your baby and delivery? Thank you 😊😊😊

Answer

So I have hypothyroidism but my tsh is always fine it just my t3 and t4 that are off. I've been on medication and the dose had to be upped 3 times wit my first pregnancy and will likely be upped soon this pregnancy as well as my levels have been off. Thyroid levels are usely easy to manage with medication
