Fact: 'leaky gut' (increased intestinal permeability) is a scientifically recognized phenomenon, but it is not a standard clinical diagnosis. Tests claiming to measure gut permeability—such as stool zonulin or lactulose/mannitol urine tests—are useful in research but lack validated cutoffs for healthy individuals. Stress can indeed affect gut barrier function via cortisol and the gut-brain axis; this is mechanistically plausible. However, no validated biomarker reliably detects 'stress-induced leaky gut' in asymptomatic people. Many companies market these tests as early warning systems for chronic diseases, which is not supported by current evidence. The predictive value is low, and false positives can lead to unnecessary anxiety or restrictive diets. My advice: only consider such tests under the guidance of a gastroenterologist or a specialist in nutritional medicine.
