Chronic renal failure


Chronic renal failure is the gradual loss of kidney function. The kidneys filter wastes and excess fluids from the blood. As kidneys fail, waste builds up.


Symptoms develop slowly and aren't specific to the disease.


Medications help manage symptoms. Later, filtering the blood with a machine (dialysis) or a transplant may be needed.
