Malnutrition in cystic fibrosis: a review.

Malnutrition is one of the main burdens of disease in cystic fibrosis (CF) along with lung disease. Data from the most recent Cystic Fibrosis Foundation registry report show the prevalence of malnutrition is decreasing in the CF population primarily from interventions focusing on preventing malnutrition. Despite success of interventions and decreased prevalence of malnutrition in this population, prevention of malnutrition in CF patients remains a dilemma that must be managed throughout the life cycle. The pathogenesis of malnutrition in CF can be further categorized into 3 main areas: increased energy losses, increased energy needs, and inadequate calorie intake. The purpose of this review is to further explore the causes of malnutrition and explain current research to prevent malnutrition in the CF population.
