Chronic kidney disease (CKD) is a decreased level of kidney functioning for a period of three months or more (1). Severity of CKD can vary, but most cases develop slowly without symptoms, are mild or moderate, and do not result in kidney failure (especially if discovered early) (1). People with CKD have an increased risk of developing heart disease or having a stroke (2).
While CKD can develop at any age, it is more common in older adults (2). About half of people aged 75 and older have some degree of CKD, although most of these cases are due to the normal aging process (2).
A routine blood test is commonly done to detect CKD and monitor people with conditions that can affect the kidneys such as diabetes or high blood pressure. Treatment can slow down the progression of CKD and reduce the risk of developing heart disease or having a stroke (2).
