What is chronic kidney disease?

Chronic kidney disease (CKD) is characterized by the irreversible loss of renal function over time. This condition typically progresses through different stages, which are defined by the level of kidney function, specifically the glomerular filtration rate (GFR). Unlike temporary renal impairments that might resolve, CKD signifies a long-term and often progressive decline in kidney function.

Patients with CKD may have a variety of symptoms that correlate with the disease's progression, and the condition is often associated with risk factors such as diabetes, hypertension, and cardiovascular disease. While medical management and lifestyle modifications can slow the progression, the damage to kidney tissue is generally not reversible, thus fitting the definition of irreversible loss of renal function.

By recognizing CKD as an ongoing and worsening condition, healthcare professionals can better provide appropriate monitoring and interventions to optimize patient outcomes and potentially delay the need for dialysis or transplantation, clarifying its chronic nature compared to other acute or temporary renal conditions.
