Can Leaky Gut Test help with fatigue?

Whether a Leaky Gut Test can help with fatigue is scientifically challenging. The concept of 'leaky gut' (increased intestinal permeability) remains controversial in research – there are no standardized, clinically validated tests to diagnose it. Most commercial tests measure markers like zonulin or antibodies against occludin, but their relevance to symptoms like fatigue is unclear. Fatigue has many causes (sleep deprivation, stress, nutrient deficiencies, thyroid issues, chronic inflammation, etc.). A leaky gut test does not replace a medical workup. Even if increased permeability were present, a causal link to fatigue is not established. Evidence-based approaches for fatigue include sleep hygiene, balanced diet, exercise, and appropriate medical diagnostics. The test may be considered exploratory at best, not a basis for treatment decisions. Beware of exaggerated marketing claims.
