There are four basic mechanisms: increased intestinal secretion (e.g., cholera), decreased intestinal absorption (e.g., enterotoxins, inflammation, or ischemia), increased osmotic load (e.g., laxatives, lactose intolerance), and abnormal intestinal motility (e.g., irritable bowel syndrome). Most cases are infectious in etiology. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/29 UR - accessemergencymedicine.mhmedical.com/content.aspx?aid=1143140488 ER -
