Leaky gut syndrome (intestinal permeability) occurs when the intestines become damaged and excessively permeable. This allows particles such as undigested food and bacteria to pass into the bloodstream, triggering an immune response. This reaction may lead to various conditions, including hypothyroidism, psoriasis, allergies, and fatigue.

If left untreated, leaky gut can result in food intolerances, digestive issues, fatigue, brain fog, skin conditions, and even depression. As many individuals may be unaware they have this condition, testing is crucial. Elevated zonulin levels are a significant marker for leaky gut and are commonly found in individuals with allergies, autoimmune diseases, and rheumatism. Therefore, regularly monitoring zonulin levels can aid in optimising overall health.

Zonulin, a protein produced by intestinal and liver cells, plays a key role in regulating intestinal permeability. It controls the "tight junctions" between the cells of the digestive tract wall, allowing nutrients to pass into the bloodstream. However, when these junctions become damaged, larger protein molecules may leak through, potentially triggering inflammation.

Our Leaky Gut Test, which measures zonulin levels, is particularly suitable for those experiencing intestinal issues. Additionally, for more complex gut issues, we recommend our comprehensive Gut Microbiome XL test. This test not only assesses the presence of leaky gut but also evaluates the status of your gut flora, including bacteria and fungal overgrowth (such as Candida), and digestive function.

The GetTested Leaky Gut Test is a stool-based test that comes with all the necessary materials. Once you’ve completed the test, simply send it to our ISO-certified lab using the pre-paid envelope provided. Your results will then be delivered digitally, offering valuable insights into your gut health.
