malabsorption syndrome

malabsorption syndrome
malabsorption syndrome n a syndrome resulting from malabsorption that is typically characterized by weakness, diarrhea, muscle cramps, edema, and loss of weight

* * *

any of a group of disorders characterized by subnormal absorption of dietary constituents, and thus excessive loss of nonabsorbed substances in the feces; the malabsorption may be due to an intraluminal (digestive) defect (e.g., pancreatic insufficiency), a mucosal abnormality (celiac disease or disaccharidase deficiency), or a lymphatic obstruction (intestinal lymphangiectasia). Unless there is a specific enzyme or transport defect, steatorrhea is usually present. Deficiency syndromes may result from excessive loss of vitamins, electrolytes, iron, calcium, or other substances.
