There is some evidence that patients with cancer of the colon or rectum have less severe diarrhea, less stomach discomfort, shorter hospital care, and require fewer chemotherapy dose reductions due to GI side effects when they take a particular strain of Lactobacillus rhamnosus, Lactobacillus GG (Culturelle).
Isosorbide is a heterocyclic compound that is derived from glucose. Isosorbide and its two isomers, namely isoidide and isomannide, are 1,4:3,6-dianhydrohexitols. It is a white solid that is prepared from the double dehydration of sorbitol. Isosorbide is a non-toxic diol produced from biobased feedstocks, that is biodegradable and thermally stable.
In summary: 1  A large amount of fluid is cycled through the bowel each day. ( 2 net reabsorption = 98%) Intestinal fluids are isotonic. 3  Water is reabsorbed passively down its osmotic gradient created by the active reabsorption of nutrients and electrolytes.bout 1500 mls/day enter the colon from the ileum. This means that over a litre per day is absorbed in the colon. The intestinal contents are essentially isotonic by the time the jejunum is reached because water can move into or out of the intestine in response to any osmotic gradient.
