Human Feces - Bristol Stool Scale

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:

  1. Separate hard lumps, like nuts (hard to pass)
  2. Sausage-shaped but lumpy
  3. Like a sausage but with cracks on the surface
  4. Like a sausage or snake, smooth and soft
  5. Soft blobs with clear-cut edges
  6. Fluffy pieces with ragged edges, a mushy stool
  7. 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:

    It’s of a rich squire in Bristol doth dwell,
    There are ladies of honour that love him well,
    But all was in vain, in vain was said,
    For he was in love with a charming milkmaid.
    —Unknown. Squire and Milkmaid; or, Blackberry Fold (l. 1–4)

    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)

    That age will be rich indeed when those relics which we call Classics, and the still older and more than classic but even less known Scriptures of the nations, shall have still further accumulated, when the Vaticans shall be filled with Vedas and Zendavestas and Bibles, with Homers and Dantes and Shakespeares, and all the centuries to come shall have successively deposited their trophies in the forum of the world. By such a pile we may hope to scale heaven at last.
    Henry David Thoreau (1817–1862)
