The Difference Between Kidney Failure and Kidney Disease

Kidney failure
Kidney failure occurs when the kidneys partly or completely lose their ability to carry out normal functions. This is dangerous because water, waste, and toxic substances build up that normally are removed from the body by the kidneys. It also causes other problems such as anemia, high blood pressure, acidosis (excessive acidity of body fluids), disorders of cholesterol and fatty acids, and bone disease in the body by impairing hormone production by the kidneys.

Chronic kidney disease
Chronic kidney disease is when one suffers from gradual and usually permanent loss of kidney function over time. This happens gradually over time, usually months to years. Chronic kidney disease is divided into five stages of increasing severity. Stage 5 chronic kidney failure is also referred to as end-stage renal disease, wherein there is total or near-total loss of kidney function and patients need dialysis or transplantation to stay alive. The term "renal" refers to the kidney, so another name for kidney failure is "renal failure." Mild kidney disease is often called renal insufficiency.
