Osmotic diarrhoea Osmotic diarrhoea is another major mechanism by which diarrhoea occurs. The causative agents are osmotically active compounds that are poorly absorbed, or not absorbed at all, in the colon and are therefore present in the lumen in a high concentration. Their osmotic effect causes fluid to flow into the lumen. When the absorptive capacity of the colon is exceeded, diarrhoea occurs. The process is physiological. No alterations occur in either the intracellular mechanisms of secretion or absorption as in secretory diarrhoea.
