Bristol Stool Chart

The chart was developed to classify human feces for medical purposes:1
  • Types 1 and 2 indicate constipation.
  • Types 3 and 4 are considered ideal stools (especially the latter), as they are easy to defecate while not containing excess liquid.
  • Types 5, 6 and 7 tend towards diarrhea.
