Maldigestion and Malabsorption

Abstract

Chronic diarrhea, associated with an increase in the fecal excretion of fat (steatorrhea), defines lipid malassimilation, which implies impairment in the digestive and/or absorptive phases of dietary fat (lipids). Impaired assimilation of carbohydrates may accompany lipid malabsorption or occur as an isolated problem. Effective problem-solving of steatorrheal or carbohydrate-mediated diarrhea is facilitated by understanding those mechanisms that characterize the normal assimilation of ingested foodstuffs. This comprehension leads to a sharply focused history and physical examination, a more accurate interpretation of laboratory test results and the rational, organ-specific selection of cost-effective specialized tests (fecal osmotic gap, D-xylose testing, Schilling test) and diagnostic procedures (hydrogen breath testing, small bowel biopsy).
