Diarrhea

In medicine, diarrhea (from the Greek, "diarrhoia" meaning "a flowing through"), also spelled diarrhoea (see spelling differences), is the condition of having frequent loose or liquid bowel movements. Acute diarrhea is a common cause of death in developing countries and the second most common cause of infant deaths worldwide. The loss of fluids through diarrhea can cause severe dehydration which is one cause of death in diarrhea sufferers. Along with water, sufferers also lose dangerous amounts of important salts, electrolytes, and other nutrients.
