Bristol stool scale
The Bristol Stool Scale or Bristol Stool Chart is a medical aid designed to classify the feces form into seven groups. It was developed by Heaton and Lewis at the University of Bristol and was first published in the Scandinavian Journal of Gastroenterology in 1997.[1] The form of the stool depends on the time it spends in the colon.[1]
The seven types of stool are:
- Type 1: Separate hard lumps, like nuts (hard to pass)
- Type 2: Sausage-shaped but lumpy
- Type 3: Like a sausage but with cracks on its surface
- Type 4: Like a sausage or snake, smooth and soft
- Type 5: Soft blobs with clear cut edges (easily |passed)
- Type 6: Fluffy pieces with ragged edges, a mushy stool
- Type 7: Watery, no solid pieces entirely liquid
Types 1 and 2 indicate constipation;[2] 3 and (especially) 4 are the preferred types of stools as they are the easiest to pass. Types 5-6 are more symptomatic of diarrhoea, while type 7 may be a sign of cholera, food poisoning, etc.
The United Bristol Healthcare NHS Trust and North Bristol NHS Trust, the largest NHS trusts in Bristol, do not, however, use the Bristol Stool Scale.
