Diarrhea is defined as the passage of loose, liquid or watery stools.
These liquids stools are usually passed more than three time a day. The attack usually lasts 3 to 7 days, but may last up to 10-14 days. Diarrhea is a major public health problem in developing countries. Diarrheal diseases cause a heavy economic burden on health services. In India, diarrheal disease is a major public health problem among children under the age of 5 years.
