I am delighted to have Dr. Eric Balcavage back on the show with us today! He appeared on the podcast once before, in Episode 105, where he spoke about thyroid physiology and chronic illness. Due to the enormous demand, we invited him to join us on the podcast once again to talk about thyroid function.

Dr. Eric is the owner and founder of Rejuvagen, a functional medicine clinic in Chadds Ford, Pennsylvania. He is also the co-host of Thyroid Answers Podcast, where he focuses on answering the pressing questions of those suffering from chronic hypothyroidism symptoms. He recently co-authored a book called Thyroid Debacle.

In this episode, Dr. Eric and I take a deeper dive into thyroid physiology, bile physiology, detoxification, and chronic illnesses. We talk about the signs and symptoms of subclinical hypothyroidism, fat malabsorption, and the use of synthetic versus non-synthetic thyroid medications. We also discuss why people can have lab values suggestive of them being persistently hypothyroid despite their use of escalating doses of medications. Stay tuned today to learn what stops the thyroid from functioning optimally and find out what you can do to maintain a healthier thyroid.
