613. IBS, Hashimoto’s, and the Thyroid–Gut Connection with Izabella Wentz

What if the gut symptoms you have been told to ignore are actually the warning sign of something much bigger? In this episode, I sit down with pharmacist and thyroid expert Izabella Wentz to unpack a connection that many people with thyroid issues completely overlook: the gut. We dive into the surprising relationship between IBS, intestinal permeability (leaky gut), and autoimmune conditions like Hashimoto’s. Izabella shares her personal story of being diagnosed with IBS years before her own Hashimoto’s diagnosis and why that early signal might have been the clue that everything else was coming. Together, we explore why so many people receive the IBS label but never uncover the real root cause and what might actually be happening inside your gut when symptoms like bloating, reflux, diarrhea, or constipation show up. We also break down the deeper physiology behind gut dysfunction and how stress, parasites, infections, low stomach acid, and even your nervous system can quietly drive chronic symptoms and immune dysfunction. If you have ever been told your labs are “normal,” handed a probiotic, and sent on your way, this conversation will challenge everything you thought you thought you knew about digestive health. Most importantly, Izabella shares how identifying the true cause behind IBS can completely change the trajectory of someone’s thyroid health and overall well-being. What you’ll learn: Why the IBS diagnosis often hides dozens of possible root causes The surprising link between IBS and future autoimmune disease How leaky gut may quietly trigger immune dysfunction The hidden gut infections many thyroid patients never test for Why stress can literally signal your gut bacteria to become more aggressive What “normal digestion” should actually look like and why many people get this wrong The overlooked role of low stomach acid in brain fog, reflux, and fatigue Why throwing every gut supplement at the problem can sometimes make things worse If you have been struggling with gut symptoms, thyroid issues, or feeling like something in your body just is not adding up, this episode will open your eyes to connections you may have never considered before.
