What to watch with Leaky Gut Test and Schlaf?

The concept of 'leaky gut' (increased intestinal permeability) is scientifically debated. Tests measuring zonulin or other permeability markers often lack robust clinical validation and are not universally endorsed by medical guidelines. Sleep (quality and duration) has a well-documented impact on gut barrier function: chronic sleep deprivation can increase permeability and promote low-grade inflammation (e.g., elevated CRP). Combining a leaky gut test with sleep analysis may offer lifestyle insights but does not provide a definitive diagnosis. Be cautious: these tests are not diagnostic for specific diseases, and results should be interpreted by a healthcare professional. Evidence is mostly mechanistic or from animal studies; human data are limited. Avoid overinterpreting marketing claims.
