was bedeutet gluckern im bauch — can a microbiome test help?

Gurgling in the abdomen (borborygmi) is usually a normal sound of intestinal peristalsis and digestion, caused by movement of gas and fluid. In most cases it is harmless and not a sign of disease. A microbiome test (stool test) is not indicated for this symptom. Commercial microbiome tests often lack clinical validation and cannot explain why someone has gurgling sounds. The evidence for such tests in non-specific symptoms is weak (marketing-based). If symptoms are persistent or painful, consult a doctor to rule out IBS, food intolerances, or other organic causes. A microbiome test should not replace medical evaluation.
