The Bristol Stool Chart lists seven types of poop.
These 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 (passes easily)
Type 6: Fluffy pieces with ragged edges (a mushy stool)
Type 7: Watery, no solid pieces; entirely liquid
