1: Separate, hard lumps, like nuts (that are often difficult to pass)

2: Sausage-shaped but lumpy

3: Sausage-shaped but with fractures on the surface

4: Sausage- or snake-like, soft and smooth

5: Soft blobs with straightforward borders (easy to maneuver )

6: Fluffy bits with ragged edges, mushy

7: Watery, no sound pieces (entirely liquid)

As a general rule, type 3 or 4 might be the ideal stool since it is not hard to pass without becoming too watery.

Type1 or 2 means that a person is likely constipated. Type 6, 5, or 7 indicates that a person likely has diarrhea.
