In this podcast we will be discussing some basic fundamentals of the thyroid hormone system. We will be expanding upon the more basic mainstream evaluation of hypothyroidism and describing how a Functional Approach might offer a better understanding of the many potential areas which may go wrong in thyroid imbalance. We will discuss how the brain, pituitary gland, thyroid gland, liver, and digestive system all have a role in the thyroid hormone experience, and just how common autoimmune thyroid can be.
