These helpers come in the form of carriers. If there is too much fructose, carriers may not be numerous enough to be effective. A lot of fructose will be retained in the bowel causing diarrhea. If not much intestine is functioning, there is a decreased amount of area to absorb food. This decreased surface area can be caused by surgical removal of a part of the bowel, diseased state of the bowel, or decreased interaction time between the intestine and food.
Diseases can cause more rapid movement of food through the intestine.
Motility modifiers should not be used long term. It is important to realize that a high frequency of bowel movements is not synonymous with diarrhea. When diarrhea begins in your pet, notify your veterinarian for help in deciding whether you should wait the diarrhea out or make an appointment to have the problem assessed. This is especially significant in young pets. Viral diarrheas, such as parvo virus, could kill your young pet.
