impaired intestinal absorption of nutrients.
malabsorption syndrome a group of disorders marked by subnormal intestinal absorption of dietary constituents, and thus excessive loss of nutrients in the stool; it may be due to a digestive defect, a mucosal abnormality, or lymphatic obstruction.

malabsorption

One of a number of disorders in which there is a failure of movement of some of the elements of the diet from the small intestine into the bloodstream so that MALNUTRITION may occur in spite of an adequate diet.

Dogs who experience a single, acute, uncomplicated episode are more likely to be able to return to a normal diet, while dogs with repeated episodes of acute pancreatitis, hyperlipidemia, or steatorrhea (large, greasy, foul-smelling stools caused by fat malabsorption) should be kept on a fat-restricted diet.
The majority of CF patients have pancreatic exocrine insufficiency, even in early infancy, which, if untreated, leads to fat malabsorption and malnutrition (5).
Vitamin D is a fat-soluble vitamin and requires some dietary fat for absorption, so fat malabsorption can compromise vitamin D status.
Supplementation with medium-chain triglycerides reduces HIV-associated intestinal dysfunction and fat malabsorption. And ready-to-use therapeutic food improves nutritional status in severely malnourished children.
The loss of magnesium through diarrhea and fat malabsorption usually occurs after intestinal surgery or infection, but it can occur with chronic malabsorptive problems such as Crohn's disease, gluten sensitive enteropathy, and regional enteritis (13).
Malabsorption in the elderly usually presents nonspecifically with weight loss, evidence of malnutrition, or functional decline.[30,31] Although diarrhea is common[16] only one third of patients with diarrhea have malabsorption.[30] Positive qualitative fecal fat identifies moderate to severe steatorrhea, but lacks sensitivity for less severe fat malabsorption. Three-day quantitative fecal fat collection is sensitive, but is difficult to collect.
Fat malabsorption has been implicated in the development of cardiac cachexia [12-14] but the relevant studies were poorly designed and uncertainty still exists about the role of fat malabsorption in cardiac cachexia.
There was no evidence for fat malabsorption, malnutrition, or cachexia, making a secondary cause unlikely.
