ICD-11

Intestinal malabsorption is a diseased condition in which absorption of food nutrients across the intestinal tract is disturbed. Impairment of single or multiple nutrients may lead to malnutrition. Protein-losing enteropathy is a diseased condition in which there is excessive loss of plasma protein into the intestine. More loss of proteins than synthesis may lead to hypoalbuminemia.

Intestinal malabsorption (syndrome) occurs due to pathological interference with the normal physiological sequence of digestion (intraluminal process), absorption (mucosal process), and transport (post-mucosal events) of nutrients in the small intestine. The concept of intestinal failure is a life-threatening severe type of intestinal malabsorption due to short bowel, structural enterocyte defects, and intestinal dysmotility etc.
