Diarrhoea is a very common symptom of intestinal tract infection. The gastrointestinal disease is characterised by very frequent (more than thrice a day) passage of liquid stool which leads to a massive loss of fluids, nutrients and electrolytes from the body. This also causes reduced absorption of nutrients and fluids. The disease, which is primarily caused by a variety of bacteria, virus and other parasitic microorganisms, is highly transmissible from person-to-person via contaminated food and drinking water. Occasionally diarrhoea can occur as an outcome of allergy, food poisoning and chronic irritable bowel syndrome as well.
