Low Thryoid Levels? (long)

September2007

Happy Thursday ladies (and Happy St. Patrick's Day!)   

Has anyone been diagnosed with low thyroid levels (hyperthyroidism)?  I've had three blood panels done in the last 12 weeks, and each one my levels have come back low.  It was tested pre-pregnancy with our IVF cycle in October and my TSH level was 1.19, which is considered normal.  Now, it's low (no number given, I guess I'll learn more today). 

Someone on the PAIF board shared that hyperthyroidism has been linked to hypermesis (severe M/S), which now makes sense to me, although I wasn't officially diagnosed with either until now.  I have only gained back 6 of the pounds 20 pounds I've lost since our BFP, and at 20 weeks, that seems on the low side.  (Especially since they wanted me to gain 40-50 pounds because of my twins!)

Just wondering if anyone is in the same boat...  It's more common that pregnancy can bring on hypothyroidism, but I have the opposite issue.  TIA!!

I was diagnosed with hypothyroidism right before I got pregnant.  They said that could have contributed to my fertility issues and I started on synthroid.  Now that I am pregnant they are monitoring my levels carefully(not that they weren't before but even more closely now) and have to up my synthroid dosages throughout the pregnancy because the baby impacts your levels.  So my thought would be that even though your levels were normal before your BFP, it's possible that they can drop due to the pregnancy.  They will probably put you on synthroid and you will have to get your blood drawn every 4-6 weeks to check that the dosage is still adequate. Also, not sure if you had this issue or not but my energy levels got SOOO much better once I was diagnosed and started taking the synthroid!  Good Luck!

Are they testing more than just your TSH?  Right now my TSH is very low but my other levels are all normal so my doc isn't as concerned.  I was very hyperthyroid for several pregnancies and yes, I had horrible morning sickness for the entire 9 months for two of them.

They retested my TSH level in January and March, and it's been low both times.  Today, they tested my T3 and T4 levels -- I should have the results in the next few days...

Thanks for the advice, ladies!!
