IBS is very much a physiological problem--it's just a different one from what 
you describe.  The peristalsys becomes spastic rather than smooth.  This can 
result in alternating constipation and diarrhea, or simply loose stools with 
undigested food in it.  Note that food is mainly broken down for absorption 
into the body in the small intestine--not the stomach.  Undigested food in 
the stool is more about the speed of bowel emptying than the speed of stomach 
emptying.

Since I have ulcerative colitus myself (with a spastic colon), I'm quite 
familiar with these problems.  It's also worth pointing out that since being 
largely paleo in my eating (I do cheat), my bowel problems have completely 
gone away.

So it'r rather mechanical than physiological problem
It probably also means faster than normal stomach empting mechanism.
I was taking large quantities of digestive enzymes with little effect so
maybe you're right.
Very interesting.
