Podcast:The Dr. Tyna Show Published On: Thu May 14 2026 Description: EP. 261: Get Strong with Me Inside my NEW Strength Vault: https://www.drtyna.com/offers/G33fSdvS In this episode, I sit down with Dr. Amy Hornaman to go deep on thyroid dysfunction, Hashimoto’s, and why so many people are misdiagnosed or undertreated. We break down T3 vs T4, reverse T3, molecular mimicry, and how stress, viral triggers, and lifestyle factors can push people over the edge into full thyroid dysfunction. This conversation also covers why lab work alone misses so much and how real thyroid treatment can change energy, mood, pain, and metabolism. Topics Discussed: → What are the signs of hypothyroidism? → Why do thyroid labs look normal? → What’s the difference between T3 and T4? → Can Hashimoto’s cause weight gain? → How does stress affect the thyroid?
