wie lange ist der darm — can a microbiome test help?

The human intestine varies in length, but on average the small intestine is about 5–7 meters and the large intestine about 1.5 meters. A microbiome test, such as those offered by MyBody-X, can analyze the composition of gut bacteria but cannot measure intestinal length. These tests may provide clues about dysbiosis or dietary adjustments, but lack clinical validation for length assessment. The evidence for microbiome tests in general health optimization is currently 'practice-based', as robust randomized controlled trials are scarce. A test might indirectly hint at inflammatory conditions affecting gut health, but length determination requires imaging like endoscopy or MRI. Consumers should not expect a microbiome test to replace medical diagnostics.
