Is Leaky Gut the Cause of your Eczema?

By Dr. Diane Angela Fong, ND & Tori Taggart, MS, CNS

leaky gut and eczema

Do you often find yourself struggling with persistent eczema, despite trying various treatments? The answer to your skin woes might lie deeper than the surface—within your gut. Emerging research suggests a strong connection between gut health and skin conditions, specifically pointing to a phenomenon known as "leaky gut." This is when the gut lining is compromised, and proteins and other substances can escape into the bloodstream, triggering a cascade of issues throughout the body.

In our previous blog post, we delved into the role of microbiome balance in skin health, discussing how the overgrowth or depletion of certain bacteria, parasites, or fungi can impact your skin. Now, it’s time to explore another layer of this complex puzzle. The health of your gut lining is equally vital. When it becomes too permeable, it can lead to a range of symptoms, from skin conditions like eczema, rashes, and acne to digestive issues such as constipation, diarrhea, gas, or bloating. Food sensitivities and autoimmune diseases are also commonly linked to this increased gut permeability.

Join us as we dive deeper into the concept of leaky gut and uncover how it might be the hidden cause of your eczema. Understanding this connection could be the key to unlocking new pathways to relief and achieving healthier, clearer skin.


By unraveling the scientific complexities of leaky gut , we aim to provide clarity on how leaky gut can serve as a fundamental root cause of eczema, empowering individuals with knowledge to address this issue at its core. Through understanding the science behind eczema and leaky gut, we pave the way for effective interventions and holistic approaches to managing and ultimately conquering this challenging skin condition.

The Intestinal Barrier

The intestinal barrier is like a protective shield in your gut, made up of a layer of special cells called enterocytes. These cells are responsible for absorbing nutrients from the food you eat and also help regulate your immune system by releasing certain signals.

In addition to enterocytes, there are other helper cells in the mix. Goblet cells produce mucus, which helps to keep things moving smoothly. Enterochromatophilic cells release hormones, Paneth cells make defensive proteins, and M cells catch harmful germs from the food you eat.

But the real superheroes of the intestinal barrier are tight junctions (TJs). Think of TJs as tiny gates that are zipper-like in-between the cells. They control what gets in and out of your gut. These gates are made up of various proteins that work together to keep everything in check. However, when something goes wrong with these gates, it's like leaving your front door unlocked. Substances that shouldn't be allowed to enter your bloodstream can slip through, causing trouble not just in the gut, but systemically.

When the structure and function of these gates are compromised, it can lead to problems like inflammatory bowel disease and celiac disease, where the gut becomes more permeable than it should be. In simple terms, the intestinal barrier and tight junctions are like the bouncers at a club—they let in the good stuff and keep out the troublemakers. Understanding how they work can help us better grasp how our gut protects us and what happens when things go awry.

Leaky Gut & Eczema

leaky gut and eczema

Leaky gut, or increased intestinal permeability, has emerged as a potential contributing factor to the development and exacerbation of eczema. Several studies have investigated the relationship between leaky gut and atopic diseases, shedding light on the intricate interplay between the gastrointestinal tract and the skin.


Intestinal Barrier Permeability in Allergic Diseases

Increased intestinal permeability allows allergens to penetrate the intestinal barrier, triggering immune responses and systemic signs of food allergy. This abnormal response to food allergens underscores the significance of gut barrier integrity in allergic diseases, including eczema. (Niewiem and Grzybowska-Chlebowczyk, 2022)

Investigating Leaky Gut in Eczema

Pike et al. conducted investigations into gastrointestinal permeability in children with atopic eczema. They observed elevated urinary excretion rates of certain sugars in children with eczema compared to controls, indicating increased permeability of the gut barrier. This heightened permeability may be linked to either primary abnormalities of the gut or intestinal mucosal damage caused by hypersensitivity reactions to food antigens.

Impact of Diet on Intestinal Permeability

Caffarelli et al. examined the effects of dietary interventions on small intestinal permeability in children with atopic eczema. While dietary restriction resulted in reduced permeability in some children with improved skin conditions, the overall impact on permeability was not statistically significant. This suggests that dietary therapy may have variable effects on intestinal permeability in individuals with eczema.

Understanding the role of leaky gut in eczema opens avenues for novel therapeutic strategies. By targeting gut barrier integrity through dietary modifications or interventions aimed at restoring intestinal homeostasis, clinicians may potentially help to alleviate eczema symptoms and improve patient outcomes.


leaky gut and eczema testing

Identifying whether you have leaky gut, scientifically known as intestinal permeability, is crucial for addressing underlying digestive issues and promoting overall wellness. One of the most effective ways to assess leaky gut is through testing, which provides valuable insights into the health of your intestinal barrier.

Get a Comprehensive Stool Analysis

A comprehensive stool analysis provides additional insights into gut health by assessing markers of inflammation, microbiome imbalances, and digestive function. Analysis of stool samples can reveal the presence of inflammatory markers, such as calprotectin and lactoferrin, which indicate heightened immune activity and intestinal inflammation. Additionally, evaluating the composition of the gut microbiome can uncover dysbiosis, an imbalance in the microbial community, which may contribute to leaky gut.

Additionally, a comprehensive stool analysis tests for zonulin levels. Zonulin is a protein that regulates the permeability of the intestinal epithelial barrier. Elevated levels of zonulin in the blood are associated with increased intestinal permeability, indicating potential leaky gut syndrome. By measuring zonulin levels through a stool test,we can evaluate the integrity of the intestinal barrier and identify signs of leaky gut. Higher-than-normal levels of zonulin suggest increased intestinal permeability, allowing toxins, bacteria, and undigested food particles to leak into the bloodstream. This can trigger inflammation, immune reactions, and digestive disturbances associated with leaky gut syndrome. Book a consultation to discuss this test with our Cleanbody Team or order the test directly.

Get a Food Sensitivity Test

High levels of food sensitivity on food sensitivity testing may also indicate leaky gut indirectly. When the intestinal barrier is compromised, undigested food particles and toxins can leak into the bloodstream, triggering immune responses and food sensitivities. Therefore, identifying numerous food sensitivities through testing can serve as an indirect indicator of leaky gut. By pinpointing specific foods that elicit an immune response, food sensitivity testing can help guide dietary interventions to support gut healing and reduce inflammation associated with leaky gut syndrome. We often see a higher level of food sensitivities of the foods most commonly consumed which indicates that those food proteins are leaking through the gut and into the bloodstream.  Sealing and healing the gut will help to reduce these sensitivities over time. Book a consultation to discuss this test with our Cleanbody Team or order the test directly.


Leaky Gut, Eczema & Diet

Leaky gut, or increased intestinal permeability, can be addressed through various lifestyle modifications and dietary interventions aimed at restoring gut barrier integrity and promoting overall gastrointestinal health. 

Avoid Food Sensitivities & Allergies

Identifying and eliminating trigger foods that contribute to food sensitivities and allergies is crucial for reducing inflammation and preventing further damage to the intestinal barrier. Conducting allergy or sensitivity testing and then following an elimination diet under the guidance of our Cleanbody Team can help pinpoint specific dietary triggers and support intestinal barrier healing and alleviate symptoms of eczema by reducing inflammation and removing one of the offenders causing irritation to the intestinal lining. 

Avoid Toxins

Reducing exposure to environmental toxins, such as pesticides, heavy metals, and pollutants, can help mitigate inflammation and oxidative stress in the gut. Choosing organic, pesticide-free foods, using non-toxic household cleaning products, and filtering drinking water can minimize toxin exposure and support overall gut health. Get tested for toxinsto understand which toxin exposures you need to clean up.

Support Intestinal Barrier Health

Promoting the integrity of the intestinal barrier is essential for preventing the translocation of harmful substances into the bloodstream. Incorporating gut-supportive nutrients and supplements, such as probiotics, prebiotics, and gut-healing compounds, can help strengthen the gut lining, enhance mucosal immunity, and promote the growth of beneficial gut bacteria.
