Kidneys filter your blood. They remove wastes and extra water. When the kidneys are diseased, they stop doing these jobs and wastes build up, damaging the body. If not treated, kidney disease can lead to kidney failure. But you can prevent kidney failure.
Early kidney disease has no symptoms. Most people don't know something is wrong until their kidneys are about to fail. The only way to tell if you have kidney disease is to get tested. Simple blood and urine tests are used to detect kidney disease.
