What is "Chewing Gum Diarrhea"?

QUESTION: You seem to delight in explaining conditions with strange names to
us. I must admit I find them interesting, and frequently use them to spice up
conversations that are growing dull. What can you tell us about "Chewing Gum
Diarrhea"?

ANSWER: I hope you don't intend to use this answer for mealtime discussions!
You are right, however, about my interest in "medical trivia". It provides a
wide range of "collectibles," and chewing gum diarrhea ranks along with the
more interesting. It is caused by eating large amounts of sugar substitutes
used to sweeten food products prepared for those who must avoid regular
sugar. The sugarlike substances, hexitols, sorbitol and mannitol cause
diarrhea by a combination of slow absorption as they speed up the contractions
of the small intestines, speeding the food on its way. The same substances
are also used to sweeten sugar-free gum, giving rise to the name. It is also
called "dietetic food diarrhea," but I guess that is a less interesting name.
Incidentally the diarrhea rapidly disappears as soon as the intake of these
chemicals is stopped.
