Enteral nutrition is indicated when medical records show full or partial non-function or disease of the structures that normally permit food to reach the small bowel.
Enteral nutrition is indicated when medical records show disease that impairs digestion and/or absorption of an oral diet directly or indirectly by the small bowel.
