Understanding Leaky Gut Syndrome: Causes, Symptoms, and Diagnosis

First things first, let’s understand what a leaky gut actually is. Leaky gut, also known as increased intestinal permeability or hyperpermeability, is a condition where the lining of your intestines becomes more porous than it should be. This phenomenon occurs when the tight junctions โ€“ the gatekeepers between the cells lining the intestines โ€“ become compromised due to a host of reasons we will investigate in the next section.

In turn, these “gaps” in the intestine lining can allow undigested food particles, toxins, and bacteria to “leak” into your bloodstream. This can trigger an immune response, as the body recognizes these foreign particles as invaders, leading to inflammation and a range of health issues, from digestive discomfort to immune system imbalances.

leaky gut diet plan: intestinal permeability

Imagine your intestinal lining as a finely woven fabric, selectively permitting nutrients and other necessary molecules to enter the bloodstream while blocking harmful substances. In leaky gut syndrome, this fabric becomes more like a sieve, allowing larger particles such as undigested food particles, toxins, and even bacteria to escape from the digestive tract and enter the bloodstream.

Having said that, it’s now time to dive into the nitty-gritty of what causes leaky gut and the telltale signs that might indicate you’re dealing with it!

What Are The Causes of Leaky Gut Syndrome?

The causes of leaky gut syndrome are diverse and often interconnected. Chronic stress, an unhealthy diet high in processed foods and sugars, excessive alcohol consumption, certain medications (like non-steroidal anti-inflammatory drugs), infections, and underlying conditions like Crohn’s disease or celiac disease can all contribute to the breakdown of the intestinal barrier.

Let’s have a closer look at each of them.

1. Unbalanced Diets, Excessive Alcohol Consumption, and Food Intolerances and/or Sensitivities

Diet plays a significant role when it comes to both causing and preventing leaky gut. Consuming a high-sugar and high-saturated fat diet, processed foods, and excessive alcohol can all contribute to gut inflammation and increased permeability. The same goes for food intolerances or sensitivities, like lactose intolerance or gluten sensitivity.

On the other hand, a diet rich in healthy fats and whole foods can actually prevent the insurgence of this insidious condition.

2. Chronic Stress

As explained in this article about the gut-brain axis, stress isn’t just in your head. Identically, it affects your gut too. Chronic stress can weaken the gut barrier and alter the balance of gut bacteria. As a consequence, this increases the chances of suffering from gut hyperpermeability.

3. Medications

Some medications, especially non-steroidal anti-inflammatory drugs (NSAIDs), like ibuprofen and aspirin, antacids, proton pump inhibitors (PPIs), steroids, immunosuppressive medications, and antibiotics can potentially lead to thinning of the gut lining, making it more susceptible to damage and leakiness

4. Infections

Infections within the gastrointestinal tract can have a significant impact on the health and integrity of the intestinal lining. When harmful bacteria, such as Salmonella, E. coli, and Campylobacter, viruses, including rotavirus and norovirus, fungal infections like Candida overgrowth, or parasites invade the gut, they can cause inflammation and increase the permeability of the intestine mucose, potentially leading to leaky gut.

5. Pre-existing Inflammatory Conditions

Conditions like Crohn’s disease and celiac disease are associated with increased gut permeability due to chronic inflammation.

6. Environmental Toxins

Exposure to toxins, such as pesticides, heavy metals, or pollutants -that can be contained also in personal care and household cleaning products– may increase the risk of suffering from gut hyperpermeability. In particular, these toxins can alter the composition of your gut microbiome โ€“ the community of bacteria living in your intestines. A disrupted microbiome can lead to gut dysbiosis, which can in turn contribute to inflammation as well as leaky gut.

7. Genetics

Lastly, genetics can also play a role in the insurgence of leaky gut. For instance, if you have genetic markers that predispose you to heightened inflammation, your gut may be more susceptible to damage from infections, toxins, or other triggers.

10 Most Common Symptoms of Leaky Gut Syndrome

The symptoms of leaky gut syndrome can manifest throughout the body, often making it challenging to diagnose this insidious condition. Digestive discomfort such as bloating, gas, and irregular bowel movements are quite common in people suffering from increased gut permeability, as are food sensitivities and allergies that may suddenly emerge.

Similarly, the immune system can become imbalanced, leading to various symptoms like fatigue, skin issues (eczema, acne), and even joint pain. Again, an unbalanced gut microbiome can impact mood and cognitive function, potentially leading to anxiety, depression, and brain fog.

Here is a list of the 10 most common symptoms of a leaky gut.

  1. Digestive Distress: This includes bloating, gas, diarrhea, constipation, and general discomfort in the abdominal area.
  2. Food Sensitivities: Developing sensitivities to certain foods, particularly those you once tolerated without issue.
  3. Fatigue: A leaky gut can lead to nutrient malabsorption, which in turn can cause fatigue and a general lack of energy.
  4. Skin Problems: Conditions like acne, eczema, or rashes may worsen or become chronic due to inflammation triggered by a leaky gut.
  5. Autoimmune Issues: Likewise, some autoimmune diseases, such as rheumatoid arthritis or Hashimoto’s thyroiditis, may be exacerbated by a leaky gut.
  6. Mood Disorders and Cognitive Dysfunction: A leaky gut has been linked to mood disorders like anxiety and depression, likely due to the gut-brain connection. The same goes for cognitive issues like difficulty concentrating or memory problems.
  7. Joint Pain: Joint pain and inflammation can result from the body’s immune response to substances leaking into the bloodstream.
  8. Autoimmune Diseases: An increased risk of autoimmune diseases may be associated with a compromised gut lining.
  9. Allergies: Heightened sensitivities to environmental allergens or an increase in allergic reactions.
  10. Weight Changes: Difficulty losing weight or unexplained weight gain can sometimes be linked to gut issues.

Remember, the symptoms of leaky gut can vary widely from person to person, and they may overlap with other conditions. If you suspect you have a leaky gut or are experiencing persistent symptoms, it’s crucial to consult a healthcare provider/gastroenterologist.

How to Diagnose Leaky Gut Syndrome

Diagnosing leaky gut can be a bit tricky, as it’s a complex and still-evolving area of research. There’s no single definitive test for diagnosing leaky gut syndrome, and healthcare professionals often use a combination of clinical evaluation, medical history, and certain tests to assess gut health.

In case you suspect you have a leaky gut or are experiencing persistent digestive issues, you can start by scheduling an appointment with a healthcare provider, such as a gastroenterologist or a functional medicine doctor. Be prepared to discuss your symptoms in detail. Mention any digestive discomfort, food sensitivities, skin issues, autoimmune conditions, or other symptoms you’ve been experiencing. Moreover, your healthcare providers will review your medical history to identify potential factors that could contribute to a leaky gut. Examples of these are past infections, medication use, dietary habits, and lifestyle factors.

Alternatively, they can recommend an elimination diet, where you temporarily remove potential trigger foods (gluten, dairy, etc.) to see if your symptoms improve. Along the same lines, food sensitivity testing can identify specific foods that might be causing immune responses.

Furthermore, as previously explained, there’s no universally accepted test specifically for leaky gut. However certain tests may provide insights into gut health and integrity. Among these are:

  • Lactulose/Mannitol Test: This involves drinking a solution containing lactulose and mannitol, two sugar molecules. The levels of these sugars in your urine can provide clues about intestinal permeability.
  • Zonulin Test: Zonulin is a protein associated with gut barrier function. Elevated levels of zonulin in the blood may suggest increased intestinal permeability.
  • IgG/IgA Antibody Testing: These tests measure antibodies against specific foods. Elevated levels might indicate a heightened immune response and potential gut issues.
  • Stool Analysis: Comprehensive stool tests can provide insights into the gut microbiome, inflammation markers, and digestive function.

Finally, analyzing the composition of your gut microbiome can provide insights into the health of your gut. Some companies -including Viome, Ombre (Thryve), and Biohm– offer at-home kits that allow you to collect a stool sample for analysis.
