MYF 39 | Low Thyroid: How To Find & Fix The Root Cause

Welcome to Episode 39!

In episode 39, we’re teaching you everything you need to know about thyroid health while trying to conceive. Screening for thyroid issues before and during pregnancy is NOT routine practice for conventional medical providers in the U.S. But we consider this one of the most important preconception tests a woman can receive and we advocate for universal screening, especially because not all cases of low thyroid function cause obvious symptoms. In this episode you’ll learn what your thyroid does and why it’s so important for fertility, pregnancy, and baby’s development, the symptoms and possible underlying causes of thyroid dysfunction, how to get the right testing and interpretation for your thyroid labs, available treatment options for low thyroid and how to choose the one that's right for you, and how to investigate and address the root cause of your thyroid issues so you can actually heal your body instead of just manage your symptoms.
