Thyroid and Pregnancy

Hi Doc,

I have a under active Thyroid and use Euthyrox 25mg and 50mg - one of each daily. Will there be problems with me or the baby if i get pregnant now and what precautions should be taken. I heard that there is a 90% chance that a baby born from a mother with a Thyroid problem will have brain damage - is this true?

Thank you

There is no harm in you taking Euthyrox during pregnancy. It would certainly be much more harmful to your baby if you continued to have a low thyroid problem. So the advice is definitely to continue taking the Euthyroid. The dose may have to be adjusted when you are pregnant.

Hi Kelly, I had the opposite problem, had an overactive thyroid (toxic), and fell pregnant. I had to stay on thyroid treatment / medication for the duration of my pregnancy, and was closely monitored by my endocrinologist. My baby is 3 months old now, all good and no problems, her thyroid levels were a bit high at birth, but stabilised within the first few weeks :)
