malabsorption

 [mal″ab-sorp´shun]
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.

mal·ab·sorp·tion

Imperfect, inadequate, or otherwise disordered gastrointestinal absorption.

malabsorption

[mal′əbsôrp′shən]
Etymology: L, malus + absorbere, to swallow
impaired absorption of nutrients from the GI tract. It occurs in celiac disease, sprue, dysentery, diarrhea, inflammatory bowel disease, and other disorders. It may result from an inborn error of metabolism, malnutrition, or any chemical or anatomical condition of the digestive system that prevents normal absorption. See also inborn error of metabolism, malnutrition.

malabsorption

The suboptimal absorption of nutrients from the GI tract.

Clinical findings
Bloating, abdominal pain, diarrhoea.
 
Aetiology
Cystic fibrosis (number one cause in US), abetalipoproteinaemia, acrodermatitis enteropathica, biliary atresia, bovine lactalbumin (cow's milk protein) intolerance, coeliac disease (gluten-induced enteropathy), sprue, juvenile pernicious anaemia, lactose intolerance, parasites (Diphyllobothrium latum, Giardia lamblia, Necator americanus, Strongyloides stercoralis), soy milk protein intolerance, vitamin B12 malabsorption.

mal·ab·sorp·tion

(mal'ab-sōrp'shŭn)
Imperfect, inadequate, or otherwise disordered gastrointestinal absorption.

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. See LACTASE DEFICIENCY SYNDROME, COELIAC DISEASE, STEATORRHOEA, RICKETS and OSTEOMALACIA.

malabsorption syndrome
a group of disorders marked by subnormal intestinal absorption of dietary constituents, and thus excessive loss of nutrients in the stool, with chronic diarrhea and weight loss; it may be due to a digestive defect, a mucosal abnormality, or lymphatic obstruction. A common disease in dogs and a major part of some of the enteric diseases of food animals. It is the pathogenesis of the diarrheas of trichostrongylosis of sheep and cattle, of the viral diarrheas of pigs and the undifferentiated chronic diarrheas of horses.
