Boo, how is the Booster today?
I have been lurking but trying not to think too much about things, but I spotted my name! My scan at 22 weeks was perfect, and, along with Little, I am now past 24 weeks so I will hopefully start to feel a bit more confident about things.
Anyway, thyroid disease in pregnancy... If you don't want a short lecture in thyroid physiology (only a small exam at the end to be check you were listening
), look away now!
Your dizziness is NOT due to your thyroid, no matter what your blood results are. The MW is talking nonsense.
If things really are that bad, then please see a doctor for a review. You might need blood tests for anaemia, or perhaps, like me, your blood pressure is just very low in pregnancy and you are going to live in a world of dizziness for the next 6 months. I eat a LOT of crisps and marmite in the hope that it will help!
Anyway, if your TSH (thyroid stimulating hormone) is low, this suggests a possible OVERactive thyroid, because your thyroid is producing enough of the thyroid hormone (T4) on its own.
HOWEVER, in the first trimester of pregnancy, when HCG is particularly high, a TSH below the normal range is normal. (This is because HCG is structurally quite similar to TSH so your body thinks you have plenty of TSH and doesn't make lots more.)
The important thing is what your T4 level is. Normal range is about 11-23 (different labs do the test slightly differently so the normal range varies between labs). If this is normal, you don't really need to do anything, other than check your thyroid receptor antibodies and TSH/T4 in about 6-8 weeks time. If it isn't normal or if you have a history of thyroid disease (can't remember if you've said before), then you might need to be seen by an endocrinologist. We won't do very much in most cases, but will keep an eye on the blood tests and on the patient.
If you want to let me know your results, I can give you more information and point you in the right direction, but the important things to remember are that this is hardly ever causes problems and that the dizziness is due to something else.
Right, going to post this now in case MN crashes and will write a second message catching up with everyone else...
