What is the Leaky Gut & Autoimmune Connection?

Leaky gut, or increased intestinal permeability, occurs when the lining of your gut becomes damaged, allowing unwanted substances—like toxins, microbes, and partially digested food—to pass into your bloodstream.

The autoimmune connection comes in when these substances trigger your immune system, sometimes leading to an overactive immune response. Over time, this may result in your body mistakenly attacking its own tissues—a process central to autoimmune diseases like rheumatoid arthritis, Hashimoto’s thyroiditis, lupus, and more.

In simple terms: A damaged gut lining can send your immune system into overdrive, setting the stage for chronic symptoms and autoimmune flare-ups.

Why It Matters for Your Health and Well-being

  • Root Cause Healing: Addressing leaky gut may help target the root cause of persistent symptoms, not just the surface issues.
  • Whole-Body Impact: Your gut is ground zero for your immune system. A compromised gut can contribute to skin issues, mental health symptoms, fatigue, inflammation, and more.
  • Long-Term Wellness: Supporting gut health can help manage existing autoimmune conditions and may even reduce the risk of developing new ones.

    Fact: While some in the medical field debate its terminology, intestinal permeability is a phenomenon studied worldwide.
  • Myth: “It’s only caused by food sensitivities.”
    Fact: Multiple factors contribute, including stress, infections, medication use (like NSAIDs), toxins, poor diet, and alcohol.
