What is Protein Energy Wasting?
Protein Energy Wasting (PEW) is a serious condition affecting individuals with chronic kidney disease (CKD), particularly those on dialysis. It is characterized by progressive loss of body protein stores and energy reserves, leading to malnutrition and decreased quality of life. PEW affects approximately 20-50% of dialysis patients and is associated with increased morbidity and mortality.
Understanding the Condition
The condition results from a complex interplay of factors including inadequate dietary intake, metabolic alterations, inflammation, and the dialysis process itself. Patients with PEW often experience muscle wasting, decreased strength, fatigue, and impaired immune function. Early identification and intervention are crucial for improving patient outcomes.
Diagnosis typically involves assessment of multiple parameters including serum albumin levels, body mass index, muscle mass measurements, and dietary intake evaluations. Healthcare providers use standardized criteria to identify and monitor PEW in at-risk populations.
