When a patient cannot ingest the necessary nutrients by eating food, either because of illness, injury, surgery, dysphagia, or changes in absorption, EN can be used to fill the void. In medical terms, we typically think of EN as supplying specialized nutrition support via tube feedings. Parenteral nutrition (PN) provides nutrition intravenously, entirely bypassing the GI tract. In general, if the GI system is functional, it is preferable to use EN rather than parenteral feedings.
