What should I know about stuhlgang zu hart kommt nicht raus#physiologische bedeutung der stuhlkonsistenz?

Stool consistency is a key physiological marker of bowel function and hydration. Hard stool that is difficult to pass typically indicates prolonged colonic transit time: the colon absorbs too much water, leaving the stool dry and lumpy. The Bristol Stool Scale (types 1–2) classifies this as constipation. Common causes include low fiber intake, inadequate fluid consumption, lack of physical activity, or side effects of medications. Gut microbiome imbalances or underlying conditions (e.g., irritable bowel syndrome, hypothyroidism) may also contribute. Physiologically, regular soft stool (types 3–4) reflects adequate hydration, fiber intake, and healthy peristalsis. Persistent constipation warrants medical evaluation to rule out serious disorders.
