The Bristol Stool Scale classifies feces into seven types by form (from type 1 hard lumps to type 7 watery), reflecting intestinal transit time and water absorption: the closer to type 1, the more constipated; the closer to type 7, the more diarrheal; type 4 is ideal. It is a clinical tool for rapid assessment of digestion.
