EEN can be effective and useful in a variety of ways.
Enteral nutrition involves the use of a nutritionally complete liquid diet that provides either all or a certain percentage of daily calories. This liquid diet is often an over-the-counter meal replacement formula. There are two different forms of enteral nutrition: Exclusive Enteral Nutrition (EEN) and Partial Enteral Nutrition (PEN).
Exclusive Enteral Nutrition
All calories come from a liquid diet (no solid food) for 6 to 8 weeks to induce remission.
- Very effective for inducing remission in children with Crohn's disease (CD) with little to no side effects.
- May be considered to induce remission at diagnosis or to get back to remission when in a flare.
- May be considered for patients with CD who have fistulas, abscesses, and strictures, or who are planning surgery.
- May be considered as a bridge to another therapy (see also Beginning Nutritional Therapy with EEN).
Partial Enteral Nutrition
Combines liquid nutrition (a specific percentage of calories from liquid diet) with solid foods.
- May be used to help maintain remission
- Best used adjunctively alongside pharmaceutical therapy
- When used as a part of the Crohn’s Disease Exclusion Diet (CDED), it may be considered to induce remission
