Abstract

Nutritional depletion is common in outpatients with COPD. Its incidence is less than inpatient populations but still about one-half of a general COPD rehabilitation population have some severe nutritional abnormality. Nutritional depletion appears to be predominantly loss of fat stores with only mild protein depletion. Nutritional depletion is correlated with markers of severity of disease. Psychologic factors do not appear to play a major role. The most important factor appears to be increased caloric expenditure rather than decreased caloric intake. The reason for the increased resting V̇O2 need at rest appears to be inefficient ventilation.
