Leaky gut is more than just a buzzword—it’s a key player in autoimmune conditions like Hashimoto’s, PCOS, and even menopause-related health issues. Your gut barrier isn’t just about digestion; it directly impacts your immune system, hormone balance, and inflammation levels. When this barrier becomes compromised, it can trigger widespread symptoms, from brain fog and joint pain to thyroid dysfunction and insulin resistance.

In this episode, we’re diving deep into the gut-hormone connection, exploring how intestinal permeability contributes to autoimmunity and why healing the gut is just one piece of the puzzle. We’ll break down the science behind leaky gut, discuss its impact on thyroid and hormone health, and share strategies for restoring gut integrity using functional medicine. If you’re a practitioner or someone struggling with chronic symptoms, this episode is packed with insights you won’t want to miss!

In this episode, Erin Holt sits down with JP Errico—inventor, entrepreneur, and co-founder of electroCore—to explore the powerful role of the vagus nerve in whole-body health. If you’ve never heard of the vagus nerve before, you’re not alone—but this key player connects the brain, gut, immune system, and autonomic nervous system, impacting everything from inflammation and digestion to stress and chronic illness. Erin and JP dive into the explosion of autoimmune conditions, the mind-body connection, and how vagus nerve stimulation could be the missing link to better health. Tune in to discover how activating this vital nerve may help restore balance and unlock healing.
