[Research Progress in Pathogenesis,Nutrition and Exercise Intervention of Patients With Protein Energy Wasting].

Protein energy wasting(PEW)is common in maintenance hemodialysis(MHD)patients,and it is associated with a variety of adverse clinical outcomes,including weight loss and increased protein catabolism.There are many studies on health interventions for MHD patients through nutrition strategies,exercise patterns and the combination of both.This article reviews the pathogenesis,diagnostic criteria and intervention measures of PEW,aiming to provide a reference for early clinical diagnosis,identification and intervention of PEW.
