What is Which is a feature of osmotic diarrhoea : and explain in detail?
Osmotic diarrhoea results from the presence of osmotically active, poorly absorbed solutes in the bowel lumen that inhibit normal water and electrolyte absorption. Ceain laxatives such as lactulose and citrate of magnesia or maldigestion of ceain food substances such as milk are common causes of osmotic diarrhoea. An increased osmotic load can be measured in the stool. This type of diarrhoea ceases with fasting.
