Parenteral nutrition in patients with diabetes mellitus: theoretical and practical considerations

Abstract

It is estimated that there are 11 million diabetics in the United States. Increasing recognition of the importance of nutrition in clinical medicine coupled with the frequent hospitalizations of the diabetic patient has heightened interest in their nutritional therapy. Patients with diabetes mellitus exhibit many abnormalities in the regulation of carbohydrate metabolism which may be accentuated during illness as part of the metabolic response to injury. An understanding of the effect of injury/illness, parenteral nutrition, and diabetes mellitus on carbohydrate metabolism is essential for the development of a rational approach to the initiation and maintenance of nutritional support in the diabetic patient.
