Chronic Renal Failure (CRF) or Chronic Kidney Disease (CKD) is the end result of a progressive loss of kidney function. As this is a gradual process, the loss of function may take place so slowly that symptoms of kidney failure only appear when they’re close to completely lost.
The final stage of chronic kidney diseases is known as End-Stage Renal Disease (ESRD). Once this stage has begun, kidneys are no longer able to remove enough waste and excess fluid from the body. Because of this, dialysis is required in order to remove these toxins from the body and prevent patient sickness.
