EEN
Pronunciation: E-E-N
Also written as: EEN — exclusive enteral nutrition
First-line treatment for pediatric Crohn's disease using exclusive nutritional therapy without solid food.
Full Definition
Exclusive enteral nutrition (EEN) is a therapeutic approach involving the complete replacement of normal diet with liquid nutritional formulas for a specified period, typically 6-8 weeks. In pediatric gastroenterology, EEN is considered first-line induction therapy for children with newly diagnosed Crohn's disease, achieving remission rates comparable to corticosteroids without the associated side effects. The treatment provides complete nutrition while reducing intestinal inflammation through mechanisms including bowel rest, alteration of gut microbiota, and elimination of dietary antigens. EEN is particularly beneficial in pediatric patients as it supports growth and development while treating the underlying disease.
Usage
Usage note: Distinguish from partial enteral nutrition (PEN); spell out on first use.
