wie lang ist der darm — what can you do yourself?

The total length of the human intestine is about 7–9 meters (small intestine ~5–7 m, large intestine ~1.5 m). What you can do yourself: A high-fiber diet (vegetables, whole grains, legumes) supports gut health, as does adequate water, regular exercise, and stress management. Probiotics and prebiotics may help the microbiome, but effects vary individually. Avoid unnecessary antibiotics and highly processed foods. Note: Intestinal length varies by individual and does not directly determine health. For persistent symptoms (bloating, constipation, diarrhea), consult a doctor. Evidence for these recommendations comes from nutritional medicine and microbiome research, but large RCTs are often lacking. Rating: practice (generally accepted practice).
