Following removal of the ileocecal valve, the absorptive processes in some patients may be affected due to the development of high concentrations of bacteria in the ileum. Severe diarrhea may occur as a result of fat malabsorption or irritation of unreabsorbed bile salts on the colonic mucosa.[38] Diarrhea also may occur when major portions of the large bowel are removed. In this case, a significant amount bicarbonate can be found in the fecal fluid, since alkaline ileal contents drain into a shortened large bowel segment, which may result in acidosis and dehydration.
But if you still have your ileocecal valve its probably due to the amount of intestine used or what part of intestine used. Its amazing how many different ways there are to make these pouches.
