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.

Food intolerance is a term used for difficulty in digesting a food due to various physiological responses associated with a particular food, or compound found. Food intolerance should not be mistaken for food allergy, which is primarily involving the immune reaction against the food.
