Chronic kidney failure, also called chronic kidney disease, describes the gradual loss of kidney function. Kidney failure is a medical condition in which kidneys fail to filter metabolic wastes and toxins out of the body and a series of symptoms will be developed .It is common, frequently un recognised and often exists together with other conditions (for example, cardiovascular disease and diabetes). When advanced, it also carries a higher risk of mortality. The risk of developing CKD(Chronic Kidney diseases ) increases with increasing age, and some conditions that coexist with CKD become more severe as kidney dysfunction advances CKD can progress to established renal failure in a small but significant percentage of people. This classification divides CKD into five stages. Stages 3-5 may be defined by glomerular filtration rate (GFR) alone, whereas stages 1 and 2 also require the presence of persistent proteinuria, albuminuria or haematuria, or structural abnormalities.
