Healing from Within: Your Guide to Understanding Leaky Gut Syndrome

August 31, 2023

In the middle of our sophisticated biology, the gut emerges as an intriguing ecosystem of health, not just a digestive hub. Consider it a busy metropolis where cell phone connectivity influences our energy. Yet, lurking in the shadows of this city is the perplexing leaky gut syndrome - a hole in the walls protecting our gut. This tiny turbulence may cause havoc, allowing undesired molecules to enter places they shouldn't. Consider poisons, germs, and undigested particles running rampant, causing a symphony of physical problems.

But don't worry, science has shown the route to rehabilitation. Tight junctions – the molecular gatekeepers – are crucial. By delving into the science of leaky gut syndrome, we may learn about its far-reaching effects on digestion, immunity, and possibly even chronic illnesses. We set out on a mission to retake power, armed with this information. We explore strategies to fill gaps, strengthen our defences, and recover the harmony of our wonderful gut city, from old dietary wisdom to current breakthroughs through this research.

Understanding Leaky Gut Syndrome:

Leaky Gut Syndrome, also known as increased intestinal permeability, is a condition where the lining of the small intestine becomes compromised, allowing toxins, undigested food particles, and other harmful substances to leak into the bloodstream. This can lead to inflammation, digestive issues, and a range of other health problems.

The intestinal barrier covers an impressive surface area of approximately 400 square metres, demanding roughly 40 per cent of the body's total energy expenditure. This fact becomes all the more striking when you consider that the brain, which is the seat of consciousness and cognition, requires only 20 per cent of the body's energy. This distinction highlights the importance of the gut barrier.

While leaky gut syndrome is not yet recognized as a formal medical diagnosis, many experts in functional nutrition believe that addressing gut health can significantly impact overall well-being. In this blog, we will explore various factors and symptoms associated with leaky gut syndrome (LGS) in depth, as well as discuss different foods and supplements that can help alleviate its effects (1)

Factors Contributing to Leaky Gut:

Various factors can disrupt the delicate balance of the gut lining and contribute to the development of a leaky gut (2). Here are some key factors that can cause leaky gut syndrome:

  • Dietary Choices: Processed foods, gluten, vegetable/seed oils, dairy products, etc.
  • Chronic Stress: Imbalanced cortisol levels can harm the gut barrier.
  • Medications: Proton pump inhibitors and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) have numerous side effects and harm the GI tract, including the gut barrier.
  • Gut Microbiome Imbalance: Dysbiosis in the bacteria living in our gut, specifically, an overgrowth of the “bad” gut bacteria, and chronic inflammation can cause damage to the gut barrier.
  • Infections: Gut infections, yeast overgrowth, and lack of diverse bacteria in the gut contribute to the development of LGS.
  • Environmental Toxins: Chemicals, pesticides and heavy metals wreak havoc on our bodies, including the GI tract and intestinal barrier.
  • Alcohol and Substance Abuse: Consumption of alcohol and substances has countless known side effects. They offer temporary high but severe, long-term damage to the body and especially to our gut health.
  • Physical Trauma: Injury or trauma to the gut can harm the delicate gut lining and lead to health issues.
  • Genetics: Hereditary factors also play a role in LGS, leaving some people more at risk for the syndrome than others, thanks to their genes.

It's crucial to recognize that although these factors can play a role in the development of leaky gut syndrome, individual responses might differ. If you suspect you might be experiencing leaky gut syndrome, let's explore the various symptoms of the condition to aid the diagnosis. 

Symptoms of leaky gut can include:

The condition can display a range of symptoms that can differ among individuals. Here are several prevalent symptoms frequently linked with leaky gut syndrome:

  • Bloating, gas, excessive flatulence, or belching.
  • Diarrhoea or constipation
  • Food sensitivities
  • Fatigue and malaise
  • Chronic fatigue
  • Low energy Levels
  • Skin issues
  • Acne
  • Eczema or psoriasis
  • Joint pain
  • Muscle aches
  • Stomach ache or cramps – discomfort after consuming certain foods may suggest gut irritation
  • Mood and cognitive changes like brain fog, mood swings, anxiety and depression
  • Unexplained weight changes
  • Nutritional deficiencies

All of these symptoms can also be caused by various other health conditions, and experiencing them doesn't necessarily indicate leaky gut syndrome.

Diagnosing gut-related issues requires a comprehensive assessment as well, preferably by an experienced professional in gut health, such as a functional medicine practitioner (3)

Diagnostic markers for Leaky Gut:

Diagnosing leaky gut syndrome can be challenging, however, figuring out if someone has a leaky gut usually involves a professional looking at their health, asking about their medical past, and analysing blood and other tests. Here are some ways that are used to diagnose leaky gut syndrome (4) (5):

  1. Medical history
  2. Lactulose-Mannitol Test 
  3. Antigenic permeability
  4. The GI-MAP (Gastrointestinal Microbial Assay Plus) test 
  5. Food Sensitivity Testing
  6. Zonulin Test

These tests might not directly show if someone has a leaky gut, and different people might have different ideas about them. It's a good idea to talk to a Functional nutrition expert who understands this well to get the right advice and a customised plan for your specific health needs. 

Dietary Approach for Leaky Gut Syndrome:

Here are foods and supplements you should incorporate into your diet to help against LGS –


Even if the recommendations above help in alleviating symptoms related to leaky gut, correctly diagnosing the actual problem and then getting targeted food and supplements help from an expert becomes essential. 

Taking care of your lifestyle:

1. Sleep Better at Night: Sleeping more can help prevent things from passing through your gut too easily.

2. Adapt Stress Management Strategies: If you manage your stress, it can stop your gut from getting leakier.

3. Avoid Birth Control Pills: Using these pills might harm the helpful bacteria in your gut, and could raise the chance of digestive issues like Inflammatory Bowel Disease (IBD).

4. Moderate Exercise Regularly: Don't overdo exercise because that can make your gut leakier. Instead, doing moderate exercise often can lower inflammation (7) (8).

The Bottom Line

In conclusion, understanding the potential impact of a leaky gut on overall health is crucial. By recognizing the symptoms, considering dietary adjustments, and adopting lifestyle changes, we can work towards supporting gut health and overall well-being. Remember, consulting a functional medicine practitioner for personalised guidance is always recommended on your journey to a healthier gut.
