Type 1 has spent the longest time in the colon and type 7 has spent the least. Stools at the lumpy end of
the scale are hard to pass and often require a lot of straining. Stools at the loose or liquid end of the
spectrum can be too easy to pass - the need to pass them is urgent and accidents can happen. The ideal
stools are types 3 and 4, especially type 4, as they are most likely to glide out without any fuss.
What type of stools are best?
* The feeling you need to go is definite but not irresistible
* Once you sit down on the toilet there is no delay
* No conscious effort or straining is needed
* The stool glides out smoothly and comfortably
* Afterwards there is only a pleasant feeling of relief
* All this is most likely if the stool is Bristol Stool Form Scale, type 4
