Current nutrition practices in adult lung transplantation

Nutrition therapy is vital to the overall management of lung transplant recipients. The objective of this review is to outline the current applications of pre- and posttransplant nutrition management of the adult lung transplant recipient. Pretransplant nutrition therapy decisions are based on cause of end-stage lung disease, transplant indications, and pretransplant nutritional status. Maintaining adequate nutrient stores is the major goal of nutrition therapy for patients awaiting transplantation. In the posttransplant course, several gastrointestinal (GI) complications such as gastroesophageal reflux, gastroparesis, and distal intestinal obstruction syndrome complicate nutritional recovery. Long-term nutrition therapy for lung transplant recipients is aimed at management of common comorbid conditions such as obesity, diabetes mellitus, hypertension, osteoporosis, and hyperlipidemia. Lung transplantation outcomes are steadily improving; however, much has yet to be explored to improve the nutrition management of these patients in both the pre- and posttransplantation course.
