ist weicher stuhlgang normal — can a DNA test help?

Soft stool is often normal, especially with high-fiber diets, increased fluid intake, or mild infections. Chronic loose stools may indicate food intolerances, irritable bowel syndrome, or inflammatory bowel disease. A DNA test (e.g., for lactose intolerance or celiac disease) can reveal genetic predispositions but cannot explain acute stool consistency. Such tests show risk, not diagnosis. Stool changes require medical evaluation, especially with blood, weight loss, or pain. MyBody-X does not offer specific DNA tests for stool consistency. Evidence for direct utility is weak – more marketing than science.
