Question

Quizplus · Accepted Answer

Malabsorption related to lactase deficiency, pancreatic enzyme or bile salt deficiency, small intestine bacterial overgrowth, and celiac disease cause osmotic diarrhea. Excessive motility decreases transit time, mucosal surface contact, and opportunities for fluid absorption, resulting in diarrhea. Primary causes of secretory diarrhea are bacterial enterotoxins, particularly those released by cholera or strains of Escherichia coli, and neoplasms, such as gastrinoma or thyroid carcinoma. Small-volume diarrhea usually is caused by an inflammatory disorder of the intestine, such as ulcerative colitis, Crohn disease, or microscopic colitis.
