Chronic kidney disease stages 1 to 4 are asymptomatic health states that are not “disease”
according to previously proposed definitions of disease.
• Reduced kidney function levels, currently called chronic kidney disease, are not abnormal in
older age groups.
• The label “chronic kidney disease” can be misinterpreted by patients and can be an obstacle
to communication.
• Relabelling the stages of “chronic kidney disease” as categories of “kidney age” could
improve patient-doctor communication and patient understanding of their diagnosis.
