Myths vs facts: Stuhlprobe and Wechseljahre

The question of myths vs. facts about stool tests and menopause is timely, as commercial microbiome testing often promises personalized insights for hormonal health. A stool test can indeed detect shifts in gut bacteria composition during menopause—such as reduced diversity or altered ratios of Firmicutes to Bacteroidetes—which are linked to estrogen decline and increased intestinal permeability. Observational studies suggest associations between the gut microbiome and menopausal symptoms like hot flashes, weight gain, and mood changes. However, the evidence remains largely associative, not causal. No validated, personalized dietary recommendations based on stool tests have been proven to alleviate menopause-specific symptoms in large clinical trials. Many consumer tests overstate their clinical utility. MyBody-X's DNA test does not include stool analysis; it covers APOE, MTHFR, and HLA-DQA1 with small effect sizes on lipid and folate metabolism. For menopause, established lifestyle interventions (exercise, balanced diet, stress reduction) currently outweigh the benefits of stool testing. Bottom line: stool tests can offer interesting insights, but they are not a diagnostic tool for menopause. Be cautious of exaggerated marketing claims.
