Mikrobiom Test: what are common causes?

A microbiome test analyzes the composition of gut bacteria. Common causes of imbalance (dysbiosis) include: low-fiber diet, frequent antibiotic use, chronic stress, poor sleep, high sugar intake, and certain medications like proton pump inhibitors. Environmental factors and infections also contribute. However, interpretation is complex: individual variability is high, and many consumer tests overstate clinical relevance. A test can offer clues but does not replace medical diagnosis. Evidence: human-moderate. Sources: none specific in context.
