In summary, the indications for nutritional support in Crohn's disease are still largely based on clinical experience rather than randomized trials. In this approach, the presence and severity of malnutrition, the severity of the stress response, and the duration of inadequate feeding become the 3 variables employed to define the need for parenteral and enteral nutrition rather than the disease diagnosis, per se. Such a schema is based on the principle that the well-nourished individual can tolerate 5 to 7 days of inadequate feeding in the setting of moderate stress with minimal functional consequence and that greater degrees of malnutrition or stress shorten this period.
