The Unseen Link: Exploring the Effects of Glyphosate on Eczema

Tommys G. | Health Consultant

Eczema, a chronic inflammatory skin condition characterized by itchy, red, and dry skin, affects millions worldwide. While its etiology is multifactorial, involving genetic predispositions, immune dysfunction, and environmental triggers, increasing attention is being paid to the role of environmental toxins in exacerbating or even initiating such conditions. Among these, glyphosate, the active ingredient in many widely used herbicides like Roundup, has drawn significant scrutiny regarding its potential dermatological impacts, including on eczema.

In this article we will investigate further on the effects of glyphosate on the skin and how it may affect different parts of the body including the skin, as research increases its findings on the relation between the digestive system and skin.

Glyphosate and Skin Irritation: What the Research Suggests

Direct dermal exposure to glyphosate-based herbicides (GBHs) has been documented to cause skin irritation. While pure glyphosate is often described as having low skin toxicity, commercial formulations contain additional ingredients, known as co-formulants or surfactants, which can significantly enhance the product's overall toxicity and its ability to penetrate the skin. These co-formulants are often implicated in observed skin reactions.

Cases of chemical burns, local swelling, bullae (blisters), and exuding wounds have been reported following prolonged accidental dermal exposure to GBHs. Furthermore, photo-contact dermatitis, a skin inflammation that occurs when certain substances on the skin react with sunlight, has also been observed. While allergic contact dermatitis (ACD) specifically attributed to glyphosate itself appears to be rare, there are documented cases where individuals developed ACD after exposure to glyphosate-containing herbicides, suggesting that either glyphosate or other components in the formulation can act as sensitizers.


Beyond Direct Irritation: Inflammation and Immune Dysregulation

The link between glyphosate and skin conditions like eczema extends beyond immediate irritant reactions. Eczema is fundamentally an inflammatory condition, and research is beginning to explore how glyphosate might contribute to systemic inflammation and immune dysregulation, factors that are central to eczema pathogenesis.

Some studies suggest that glyphosate can upregulate the expression of pro-inflammatory cytokines like IL-1β, TNF-α, and IL-6. While these studies have primarily focused on other organ systems, the systemic inflammatory potential of glyphosate could theoretically contribute to the chronic inflammatory state seen in eczema. Moreover, there's evidence that pesticide exposure, including glyphosate, can impact the gut microbiome and potentially lead to "leaky gut," which in turn can activate pro-inflammatory cascades throughout the body, including the skin.

For individuals with eczema, who often have a compromised skin barrier, exposure to environmental toxins may be particularly problematic. A dysfunctional skin barrier allows for easier penetration of irritants and allergens, potentially leading to increased inflammation and exacerbation of symptoms. While direct causal links between glyphosate exposure and the development or worsening of eczema are still under active investigation, the existing evidence on skin irritation and systemic inflammatory effects raises concerns.

Occupational and Environmental Exposure

Agricultural workers and individuals living in close proximity to areas where glyphosate is heavily used are at a higher risk of exposure. Studies have shown that farmworkers can experience elevated rates of eczema and itchy rashes. This highlights the importance of understanding the cumulative impact of various pesticide exposures on dermatological health.

Glyphosate found in food

Among the foods with the highest presence of glyphosate there are grains as rice, wheat, oats as well as nuts including peanuts, for this reason, people ingesting this food may found a link between the ingestion of these particular foods and trigger of allergic reactions on the skin. It is important to remain vigilant to these associations and to test yourself in your body using a food diary of reactions and different type of foods ingested.

Another way of testing the presence of glyphosate and how this may be affecting the skin is testing the same product, for example wheat, and testing both the organic and non organic version of the product to assess if the allergic reaction is coming from the gluten in the wheat, as it may be the case with gluten allergy or gluten intolerance, or due to the presence of glyphosate in the food.

Conclusion

While more comprehensive epidemiological studies are needed to definitively establish a direct causal link between glyphosate exposure and eczema, the available research points to several concerning possibilities. Glyphosate-based herbicides, particularly due to their co-formulants, can cause direct skin irritation and chemical burns. Furthermore, the potential for glyphosate to induce systemic inflammation and disrupt immune function raises questions about its broader impact on chronic inflammatory skin conditions like eczema. As research continues to unravel the complex interplay between environmental factors and dermatological health, minimizing exposure to such chemicals, particularly for those with pre-existing skin sensitivities, remains a prudent recommendation.
