warum bin ich so müde test — can a microbiome test help?

A microbiome test can reveal imbalances in gut bacteria that have been linked to fatigue in some studies, e.g., after antibiotics or in conditions like IBS. However, fatigue is a highly nonspecific symptom with many causes (sleep deprivation, stress, iron deficiency, thyroid disorders, depression, long COVID, etc.). The evidence for a direct causal role of the microbiome in general fatigue is mostly mechanistic or based on small observational studies. A microbiome test alone cannot diagnose the reason for your tiredness. It is best to first consult a doctor for standard blood work and clinical evaluation. The test may provide supportive insights, but be cautious of marketing claims that overstate its power. Current guidelines do not recommend microbiome testing for fatigue outside of research.
