84. Your Thyroid Labs Are 'Normal' But You Feel Terrible - Here's Why
*Episode Recorded live at Training.
If your thyroid labs keep coming back "normal" but you're exhausted, gaining weight, losing hair, and feeling like you're falling apart... if your doctor keeps checking TSH and telling you everything's fine... if you've been on thyroid medication for years but still feel terrible... this episode is your wake-up call.
Dr. Terri sits down with Dr. Cassie Smith, an endocrinologist and hormone specialist, for a game-changing conversation about why the standard approach to thyroid testing is failing millions of people. This isn't your typical thyroid talk - it's the truth about why TSH alone is a useless marker after you start treatment, why 40-60% of Americans are walking around with suboptimal thyroid function, and what your doctor should actually be checking.
WHAT YOU'LL DISCOVER:
→ Why TSH is only a screening tool (and becomes irrelevant once you're on medication)
→ The shocking truth: nobody's checking your Free T3 - the hormone that actually matters
→ Why conversion of T4 to T3 breaks down (stress, gut dysbiosis, insulin resistance)
→ The deiodinase enzymes that 93% of people can't optimize due to metabolic dysfunction
→ Why higher Free T3 levels = lower cardiovascular mortality and better outcomes
→ The "normal range" scam: why lab ranges are based on sick Americans, not optimal health
→ How your gut controls ALL hormone metabolism (thyroid, estrogen, testosterone, cortisol)
→ Why fixing thyroid without fixing gut health is a Band-Aid approach
This isn't about ONE blood test. It's about understanding the whole system.
