what can cause prolonged diarrhea
It is the opposite of constipation. The word diarrhea with its odd spelling is a near steal from the Greek diarrhoia meaning a flowing through.. Diarrhea can be acute, that is, sudden in onset and short-lived, or it may be prolonged. Most acute episodes of diarrhea are due to viral infections and last three to five days. Prolonged diarrhea -- lasting more than four to six weeks -- usually is due to an underlying gastrointestinal disease, the most common of which are diseases that cause inflammation and malabsorption of food.
