Is Stuhlprobe useful for Darmgesundheit?

Whether a stool sample is useful for gut health requires a nuanced answer. A stool sample can reveal the composition of your gut microbiome—the bacteria, fungi, and other microorganisms living in your intestine. Companies like MyBody-X offer gut microbiome tests that analyze this. The scientific evidence for the clinical utility of such tests is moderate. There is strong evidence linking the microbiome to various health aspects such as digestion, immunity, and even mood. However, interpreting results is complex: there is no universal definition of a 'good' or 'bad' microbiome, and most findings come from correlational studies. For concrete actionable advice (e.g., dietary changes), the data is often still insufficient. Additionally, test results can vary between labs and over time. A stool sample can be a useful tool in a holistic diagnostic approach, but it does not replace medical evaluation for symptoms. Caution is warranted against exaggerated marketing claims that present a stool test as a simple solution for complex gut issues. Evidence: human-moderate.
