Bristol Stool Scale
The Bristol stool scale is a medical aid designed to classify the form of human feces into seven categories. Sometimes referred to in the UK as the "Meyers Scale," it was developed by K.W.Heaton at the University of Bristol and was first published in the Scandinavian Journal of Gastroenterology in 1997. The form of the stool depends on the time it spends in the colon.
The seven types of stool are:
- Separate hard lumps, like nuts (hard to pass)
- Sausage-shaped but lumpy
- Like a sausage but with cracks on the surface
- Like a sausage or snake, smooth and soft
- Soft blobs with clear-cut edges
- Fluffy pieces with ragged edges, a mushy stool
- Watery, no solid pieces. Entirely Liquid
Types 1 and 2 indicate constipation. Types 3 and 4 are optimal, especially the latter, as these are the easiest to pass. Types 5–7 are associated with increasing tendency to diarrhea or urgency.

Famous quotes containing the words bristol, stool and/or scale:
“Through the port comes the moon-shine astray!
It tips the guard’s cutlass and silvers this nook;
But ‘twill die in the dawning of Billy’s last day.
A jewel-block they’ll make of me to-morrow,
Pendant pearl from the yard-arm-end
Like the ear-drop I gave to Bristol Molly—
O, ‘tis me, not the sentence they’ll suspend.”
—Herman Melville (1819–1891)
“Oh, to have a little house!
To own the hearth and stool and all!
The heaped-up sods upon the fire,
The pile of turf against the wall!”
—Padraic Colum (1881–1972)
“The most perfect political community must be amongst those who are in the middle rank, and those states are best instituted wherein these are a larger and more respectable part, if possible, than both the other; or, if that cannot be, at least than either of them separate, so that being thrown into the balance it may prevent either scale from preponderating.”
—Aristotle (384–322 B.C.)
