was tun wenn der stuhl zu hart ist — what does this mean exactly?

Hard stool (constipation) means stool remains in the colon too long, causing excessive water reabsorption. Common causes include low fiber intake, dehydration, lack of exercise, stress, or medication side effects. What to do? Increase fluid intake (at least 1.5–2 L/day), eat fiber-rich foods (flaxseeds, psyllium husk, whole grains), exercise regularly, and establish a consistent bowel routine. If constipation persists or you notice blood, consult a doctor to rule out underlying conditions (e.g., hypothyroidism, bowel obstruction). The provided context does not cover this topic; the answer is based on general medical knowledge.
