There are four basic mechanisms: increased intestinal secretion (eg, cholera), decreased intestinal absorption (eg, enterotoxins, inflammation, or ischemia), increased osmotic load (eg, laxatives, lactose intolerance), and abnormal intestinal motility (eg, irritable bowel syndrome). Approximately 85% of cases are infectious in etiology. SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/03/28 UR - accessemergencymedicine.mhmedical.com/content.aspx?aid=56272720 ER -
