Hashimotos isn't just a thyroid disease-it may actually begin in the gut.

If you've been told your thyroid labs are "normal" but you still struggle with fatigue, bloating, constipation, IBS, or autoimmune symptoms, this episode could change the way you think about your health.

I sit down with Dr. Izabella Wentz, PharmD-better known as the Thyroid Pharmacist and one of the world's leading experts on Hashimoto's disease - to uncover the powerful connection between gut health, autoimmune disease, and thyroid function.

Dr. Wentz explains why IBS is often not a true diagnosis, but a collection of symptoms with more than 30 possible root causes. Together, we explore why conventional medicine frequently misses these underlying issues and how identifying the real drivers - from intestinal permeability and SIBO to food sensitivities, medications, infections, and even heavy metal exposure - can help people finally find lasting relief.

Whether you're living with Hashimoto's, IBS, or another autoimmune condition, this conversation offers a practical roadmap for uncovering the root cause and supporting long-term healing.

In this episode, you'll learn:

Why gut health is critical for thyroid function and autoimmune healing
The surprising connection between Hashimoto's disease and IBS
Why IBS is a symptom - not a diagnosis
The 30+ root causes that may be driving digestive symtpoms
How intestinal permeability ("leaky gut") contributes to autoimmune disease
The biggest food, medication, and lifestyle triggers for IBS
Which functional medicine tests can uncover hidden gut dysfunction
How targeted treatment can improve symptoms and support long-term remission

If you've been searching for answers beyond symptom management, this episode provides an evidence-based look at the gut-thyroid connection and what it really takes to restore health.
