Why Is Your Gut Leaking, And What Does That Actually Mean?

Is leaky gut real, or just a wellness buzzword? In this episode of The Habit Healers Podcast, I separate the real science of intestinal permeability from the zonulin tests and supplements being sold around it, and I show you how a leaky gut wall can quietly drive inflammation and high blood sugar even when you have no gut symptoms at all.Here’s what I want you to know: the gut wall really does leak, and researchers have measured it for over thirty years in conditions like type 2 diabetes, metabolic syndrome, and fatty liver disease. The biology is real. What the wellness industry got wrong is the products built on top of it. In this episode I walk through what actually damages the gut barrier, why common pain relievers like ibuprofen and naproxen matter more than most people realize, and how the gut connects to your metabolism through your liver. Then I give you a practical, research-backed gut barrier repair protocol you can start this week.What you’ll learn in this episode:* Why “leaky gut syndrome” isn’t a real diagnosis, but increased intestinal permeability is real and measurable* How NSAIDs, alcohol, stress, and ultra-processed foods damage your gut wall* The link between gut health, insulin resistance, and chronic inflammation* How to build a fiber and butyrate floor to repair the gut lining* What the research says about probiotics and zinc carnosine for gut barrier support* The sleep and stress habits that drive overnight gut wall repairDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/why-is-your-gut-leaking-and-what?r=4t8jxgCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
