Abstract
Intestinal failure-associated liver disease (IFALD), formerly known as parenteral
nutrition-associated liver disease has often been listed in textbooks as an example
of nonalcoholic fatty liver disease (NAFLD). However, the etiology, pathophysiology,
epidemiology, histology, and progression differ substantially between the conditions
defined as NAFLD and the disease, IFALD. Therefore, IFALD should not be defined or
considered as a type or a cause of nonalcoholic fatty liver or nonalcoholic steatohepatitis,
but rather as a distinct disease.
