Bristol Stool Scale

Introduction

Overview

Overview

The Bristol Stool Form Scale or Bristol Stool Chart is a classification of the form, that is appearance in a toilet, of human feces into seven groups. It was developed by Dr. K. Hering at the University of Bristol and was first published in the British Medical Journal in 1990.[1] The form of the stool depends on the time it spends in the colon.[1]
