What is chronic kidney disease (CKD)?
Chronic kidney disease occurs when your kidneys are damaged and no longer work as well as they should. Normal, healthy kidneys remove waste from the blood. The waste then leaves your body in your urine. The kidneys also help control blood pressure and make red blood cells. If you have chronic kidney disease, your kidneys cannot remove waste from the blood as well as they should. Almost 20 million people in the United States have this disease.
