Magen-Darm-Gesundheit: can a microbiome test help?

A microbiome test can show the composition of your gut bacteria (e.g., diversity, abundance of specific strains). This is mechanistically plausible – low diversity is often linked to inflammation or metabolic issues. However, the test is a single snapshot that fluctuates with diet, medications, stress, and menstrual cycle. It cannot diagnose conditions like IBS or Crohn’s disease, nor provide evidence-based personalized dietary advice. The evidence is mostly mechanistic; clinical trials demonstrating a benefit for gut health are limited. The test may serve as a starting point for lifestyle changes but should not replace medical evaluation. Safety note: always consult a doctor for gastrointestinal symptoms.
