The gut microbiome changes with age – diversity and stability often decline, linked to increased inflammation and reduced immune function. The MyBody-X Gut Microbiome Test can provide an overview of bacterial composition, but reference ranges are primarily based on middle-aged adults. It is not validated for seniors. The test is not diagnostic and does not replace medical evaluation for symptoms like diarrhea, constipation, or bloating. Studies suggest that a high-fiber diet, adequate hydration, and possibly probiotics can support gut health in older adults, but individual responses vary. The test may serve as motivation for dietary changes but should not be seen as medically necessary. Evidence: practice/marketing. Caveat: no clinical validation for seniors.
