Leaky Gut: What It Is and How to Support Your Gut Health

Your digestive system is more than just a food processing unit — it’s a critical part of your overall health. When the lining of your intestines becomes damaged or overly permeable, it can lead to what’s commonly called “leaky gut” or increased intestinal permeability.

While “leaky gut” is not an official medical diagnosis, more research is exploring its connection to a variety of health conditions, from digestive issues to autoimmune disorders.

What Is Leaky Gut?

The lining of your intestines acts as a barrier, allowing nutrients to pass into your bloodstream while keeping harmful substances out. In leaky gut, the tight junctions between the cells of the intestinal wall become loose, allowing:

• Partially digested food

• Toxins

• Bacteria

to “leak” into the bloodstream, potentially triggering inflammation and immune responses.

Possible Causes of Leaky Gut

Several factors may contribute to increased intestinal permeability, including:

• Poor diet (high sugar, processed foods, excessive alcohol)

• Chronic stress

• Imbalance of gut bacteria (dysbiosis)

• Long-term use of NSAIDs or certain medications

• Chronic inflammation or infections

Common Symptoms

Leaky gut symptoms can overlap with other conditions, but may include:

• Bloating, gas, or abdominal discomfort

• Food sensitivities

• Fatigue

• Brain fog

• Skin issues (eczema, acne)

• Joint pain

How to Support a Healthy Gut Lining

You can take steps to strengthen your gut barrier and improve overall digestive health:

1. Eat a nutrient-rich diet – Focus on whole foods, lean proteins, fruits, vegetables, and healthy fats.

2. Add gut-friendly foods – Fermented foods (yogurt, kefir, sauerkraut), bone broth, and fiber-rich foods.

3. Limit irritants – Reduce processed foods, refined sugar, alcohol, and artificial additives.

4. Manage stress – Mindfulness, deep breathing, and adequate sleep help reduce inflammation.

5. Consider probiotics and prebiotics – To support a balanced gut microbiome.

6. Work with a provider – Functional medicine testing can help identify food sensitivities or imbalances contributing to symptoms.
