Abstract
Japan is an aging society and the number of elderly chronic kidney disease (CKD) patients is increasing. As physiological function declines with age, patients with CKD and dialysis patients often develop sarcopenia and flail due to the decline in renal function and presence of many comorbidities. It is important to prolong the healthy lifespan of elderly people, and we believe that it is essential for the well-being of elderly CKD patients to maintain physical function. As such, approaches from physical function, nutritional, and social aspects are important. Based on the concept and diagnosis of basic sarcopenia and flail, we examined the frequency, prognosis, and characteristics of sarcopenia and flail in CKD patients from prior reports.
