The Bristol Stool Scale is a medical classification system developed at the University of Bristol. It categorizes stool into seven types based on form - from hard lumps (Type 1) to entirely liquid (Type 7). Types 3 and 4 are generally considered ideal. Gastroenterologists worldwide use this scale for diagnosis and treatment.
