My Gut Can Leak?! Understanding Leaky Gut.

Introduction: Leaky gut, also known as increased intestinal permeability, is a condition characterized by a compromised gut lining that allows substances to pass through the intestinal barrier and enter the bloodstream. This can trigger inflammation and potentially contribute to various health issues. In this blog post, we will delve into the definition of leaky gut, explore its development, discuss common risk factors/causes, and provide four effective recommendations for treating this condition.


What is Leaky Gut? Leaky gut occurs when the tight junctions between cells lining the intestinal wall become weakened or damaged, creating gaps that allow undigested food particles, toxins like Lipopolysaccharides (bacterial endotoxins), and bacteria to leak into the bloodstream. This can trigger an immune response, leading to chronic inflammation and potential health complications. Repeated immune reactions can further exacerbate the condition leading to a negative feedback loop, perpetuating symptoms.

Causes and Risk Factors of Leaky Gut:

  1. Poor Diet: Consuming a diet high in processed foods, sugar, unhealthy fats, and lacking in fiber can contribute to gut inflammation and compromise the integrity of the intestinal lining.

  2. Chronic Stress: Prolonged stress can disrupt the balance of gut bacteria, increase intestinal permeability, and weaken the gut barrier.

  3. Medications: Frequent use of nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, and proton pump inhibitors (PPIs) can impact gut health and contribute to leaky gut.

  4. Dysbiosis: An imbalance in the gut microbiota, with an overgrowth of harmful bacteria and a decrease in beneficial bacteria, can lead to intestinal permeability.

  5. Low vitamin D: Low vitamin d is associated with decreased barrier function in the gut lining.

  6. Alcohol consumption: Too much alcohol, or really alcohol in general, affect the gut lining

  7. Artificial sweeteners: sorbitol, mannitol, erythritol are bad news for the gut

  8. Gluten/wheat: Even in non Celiac disease patients gluten is inflammatory and may increase the release of zonulin from the liver which further opens tight junctions and allows debris to enter the blood stream.


Effective Recommendations for Treating Leaky Gut:

  1. Dietary Modifications: Adopt a gut-friendly diet that includes whole, unprocessed foods rich in fiber, antioxidants, and anti-inflammatory properties. Incorporate foods like vegetables, fruits, lean proteins, healthy fats, and fermented foods to support gut health.

  2. Probiotics and Prebiotics: Probiotic supplements containing beneficial strains like Lactobacillus and Bifidobacterium can help restore a healthy balance of gut bacteria. Prebiotics, found in foods like garlic, onions, and asparagus, provide nourishment for beneficial bacteria.

  3. Gut-Healing Supplements: Certain supplements, such as L-glutamine, zinc carnosine, quercetin, and omega-3 fatty acids, can support gut healing and reduce inflammation. Carminative herbs like slippery elm, marshmallow root, aloe vera. Consult with a healthcare professional for personalized recommendations.

  4. Stress Management and Lifestyle Changes: Implement stress-reducing practices such as meditation, exercise, quality sleep, and self-care activities. Additionally, avoid smoking, reduce alcohol consumption, and manage environmental toxin exposure to support gut health.


Conclusion: Leaky gut, characterized by increased intestinal permeability, can have far-reaching effects on overall health. By understanding its causes, addressing dietary factors, incorporating probiotics and prebiotics, considering gut-healing supplements, and implementing lifestyle changes, individuals can support gut health, reduce inflammation, and promote a stronger gut barrier.

Remember, it's important to consult with a healthcare professional for a comprehensive evaluation and personalized treatment plan if you suspect you have leaky gut or are experiencing related symptoms.
