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

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

malabsorption

(măl′əb-zôrp′shən, -sôrp′-)
n.
Defective or inadequate absorption of nutrients from the intestinal tract.

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.

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

Defective or inadequate absorption of nutrients from the intestinal tract.

malabsorption

impaired absorption of nutrients from the digestive tract. Causes include disease of the small intestine or surgical removal of a major part of it, and lack of digestive enzymes or bile salts.

malabsorption,

n improper absorption of nutrients, characterized by deficiency of carbohydrates, fats, minerals, proteins, and vitamins and excess fat in the stool.

mal·ab·sorp·tion

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

malabsorption

impaired intestinal absorption of nutrients.

fat malabsorption
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.

Causes of vitamin D deficiency include obesity, fat malabsorption syndromes, bariatric surgery, nephrotic syndrome, a wide range of medications (anticonvulsants and anti-HIV/AIDS drugs), chronic granuloma-forming disorders, some lymphomas, and primary hyperthyroidism.
Because bacterial metabolism alters folic acid status and intestinal bacterial colonization is altered by nutritional factors and carbohydrate malabsorption syndromes, dietary measurements should not rely solely on folic acid supplementation but should also consider carbohydrate malabsorption syndromes, especially fructose malabsorption.
Used in the non-invasive assessment of intestinal permeability, the test demonstrated its superior sensitivity as compared to the existing d-xylose test in measuring intestinal permeability, a measurement used in the diagnosis of gastrointestinal malabsorption syndromes, such as celiac disease, colitis, Crohn's disease, and Irritable Bowel Syndrome.
