Chronic kidney disease occurs when one suffers from gradual and usually permanent loss of kidney function over time. This happens gradually, usually months to years.
Chronic kidney disease is divided into five stages of increasing severity. The term “renal” refers to the kidney, so another name for kidney failure is “renal failure.” Mild kidney disease is often called renal insufficiency. With loss of kidney function, there is an accumulation of water; waste; and toxic substances, in the body, that are normally excreted by the kidney. Loss of kidney function 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.
Other causes of chronic kidney disease include:
