    This topic provides information about chronic kidney disease. If you are looking for information about sudden kidney failure, see the topic Acute Kidney Injury.

    Having chronic kidney disease means that for some time your kidneys camera.gif have not been working the way they should. Your kidneys have the important job of filtering your blood. They remove waste products and extra fluid and flush them from your body as urine. When your kidneys don't work right, wastes build up in your blood and make you sick.

    Chronic kidney disease may seem to have come on suddenly. But it has been happening bit by bit for many years as a result of damage to your kidneys.

    Each of your kidneys has about a million tiny filters, called nephrons. If nephrons are damaged, they stop working. For a while, healthy nephrons can take on the extra work. But if the damage continues, more and more nephrons shut down. After a certain point, the nephrons that are left cannot filter your blood well enough to keep you healthy.

    One way to measure how well your kidneys are working is to figure out your glomerular filtration rate (GFR). The GFR is usually calculated using results from your blood creatinine (say "kree-AT-uh-neen") test. Then the stage of kidney disease is figured out using the GFR. There are five stages of kidney disease, from kidney damage with normal GFR to kidney failure.

    There are things you can do to slow or stop the damage to your kidneys. Taking medicines and making some lifestyle changes can help you manage your disease and feel better.

    Chronic kidney disease is also called chronic renal failure or chronic renal insufficiency.

    Chronic kidney disease is caused by damage to the kidneys. The most common causes of this damage are:
