ist weicher stuhlgang normal — what does this mean exactly?

Whether soft stool is normal depends on context. Stool consistency varies with diet (fiber, fat, fluids), gut microbiome, medications, and intestinal transit time. The Bristol Stool Chart classifies types 4–5 (soft, smooth logs) as healthy. Loose or watery stool (types 6–7) indicates diarrhea, often due to infection, food intolerance, or stress. For some individuals, chronically soft stool without other symptoms may be their normal baseline, especially with high caffeine or fructose intake. The provided context (ESR1 gene, nutrigenetics methodology, skin aging, hsCRP) does not directly address stool consistency. Genetic tests for lactose or fructose intolerance may offer clues but are not diagnostic alone. Persistent changes, blood in stool, weight loss, or abdominal pain warrant medical evaluation. The evidence for 'soft stool is normal' is based on clinical practice and general physiology, not on specific genetic or biomarker data from the given sources.
