Ans - Diarrhoea is of the following types:Secretory diarrhoea – Excess fluid is secreted into the intestines.Osmotic diarrhoea – Caused when too much water is drawn into the bowels.Motility-related diarrhoea – Where intestines are too active and transport intestinal contents with great speed in order that there's not enough time to soak up water and electrolytes. This results in loose and watery stools.Collagenous colitis – It is a condition of the body in which the intestinal lining is damaged so that it cannot absorb water and electrolytes.Inflammatory diarrhoea – Where intestines are damaged due to bacterial or fungal infections.
