Myths vs facts: Mikrobiom Test and Darmgesundheit

Gut microbiome tests are popular but surrounded by myths. **Fact:** They provide a snapshot of bacterial composition and can indicate imbalances (dysbiosis) linked to digestive issues like bloating or fatigue. **Myth:** They diagnose specific food intolerances or diseases. That requires elimination diets or clinical tests (e.g., lactose breath test). Interpretation is complex: the microbiome shifts with diet, environment, and even time of day. Genetic factors like FUT2 secretor status influence bacterial adhesion but are a static predisposition, not a direct measure of current gut health. Many providers overstate clinical utility; results should be used as complementary insight, not a standalone basis for treatment. For persistent symptoms, consult a physician. Evidence: partly human-observational, partly marketing.
