Sarcopenia in chronic kidney disease – A brief review

Sarcopenia is a progressive age -related loss of muscle mass associated with a decline in muscle function and physical performance. Patients with chronic kidney disease experience substantial loss of muscle mass, weakness, and poor physical performance. Indeed, with the progression of chronic kidney disease, skeletal muscle dysfunction contributes to mobility limitation, loss of functional independence, and vulnerability to disease complications. There is a lack of robust data on the negative effect of the impact of kidney disease on skeletal muscle dysfunction, as well as on screening and treatment strategies that can be used in clinical practice to prevent functional decline and disability. Therefore, sarcopenia may be an underestimated condition with major implications for people with chronic kidney disease, even before the start of dialysis, which makes research into this topic necessary. The purpose of this review is to expand on some fundamental topics of sarcopenia, with an emphasis on the setting of chronic kidney disease patients.
