Evidence check: Stuhlprobe in the context of Darmgesundheit

Stool sample analysis for gut health is a promising but scientifically immature area. MyBody-X offers a microbiome test that examines the composition of gut bacteria. Results can indicate microbial diversity and the presence of certain bacterial strains linked to digestion or immunity. However, the evidence for clinical utility is mostly marketing-driven. Many claimed associations (e.g., with weight, mood, or chronic diseases) stem from observational studies with small effect sizes and lack confirmation in randomized controlled trials. Moreover, standardized reference ranges are missing, and results can vary significantly between labs. A stool test can serve as a screening tool or lifestyle inspiration, but it does not replace medical diagnosis. For serious symptoms (blood in stool, persistent diarrhea), clinical evaluation (e.g., colonoscopy, calprotectin test) is essential. Interpretation should always involve a physician or dietitian. Overall: useful for orientation, but interpret with caution.
