wie kann ich mein mikrobiom verbessern — when to see a doctor?

Improving your microbiome is an active area of research, but evidence for specific interventions is still limited. General recommendations include a high-fiber diet (vegetables, legumes, whole grains), fermented foods (yogurt, kefir, sauerkraut), and avoiding unnecessary antibiotics. Probiotics may help but are not standardized. You should see a doctor if you have persistent gastrointestinal symptoms (bloating, diarrhea, constipation), after antibiotic therapy with severe symptoms, if you suspect small intestinal bacterial overgrowth (SIBO), or if you are immunocompromised and considering probiotics. Also seek medical advice for sudden, unexplained changes in digestion or weight loss. MyBody-X tests do not provide medical microbiome diagnosis; they are lifestyle products. The science is still emerging, so recommendations are often preliminary.
