The thyroid is a butterfly-shaped gland located in the lower front of the neck. It makes thyroid hormone which, in turn, goes into the bloodstream. This process creates energy and enhances the activity of just about every function in your body. It determines your mood, your skin and hair health, body temperature, blood sugar levels, hormonal function, and whether you're more likely to gain weight or lose weight. Today's guest is Dr. Izabella Wentz. She is an internationally-acclaimed thyroid specialist and licensed pharmacist. She's dedicated her career to addressing the root causes of why the thyroid can go haywire and just doesn't function properly. Dr. Wentz is a New York Times Bestselling author. In her new book, Hashimoto's Protocols, she discusses the most common auto immune condition in the United States. For complete show notes, visit www.kathysmith.com/podcast.
