What is the main definition of Chronic Kidney Disease (CKD)?

Chronic Kidney Disease (CKD) is primarily defined as a condition characterized by irreversible kidney damage that persists for three months or more. This definition encapsulates the essential nature of CKD, emphasizing the duration and the permanence of kidney impairment. Unlike acute kidney injuries, where recovery is possible and typically occurs within three months, CKD indicates that the kidney damage is ongoing and likely progressive. This prolonged period of damage leads to a gradual decline in kidney function, which can ultimately result in end-stage renal disease. A thorough understanding of this definition is crucial for professionals in nephrology, as it informs the management and monitoring strategies for patients suffering from renal impairment.
