Kidney Disease
Chronic kidney disease (CKD and chronic renal disease) means that there’s damage to your kidneys and they aren’t working as well as they should. Your kidneys are like a filter in your body — filtering out wastes, toxins and extra water from your blood. They also help with other functions like bone and red blood cell health. When your kidneys begin to lose their function, they can’t filter waste, which means the waste builds up in your blood.
Kidney disease is called “chronic” because kidney function slowly decreases over time. CKD can lead to kidney failure, which is also called end-stage kidney disease. Not everyone with CKD will develop kidney failure, but the disease will often worsen without treatment. There’s no cure for chronic kidney disease. But there are steps you can take to slow kidney damage. Treatments like dialysis and transplantation are options for kidney failure (end-stage kidney disease).
What do your kidneys do?
You have two kidneys. They’re bean-shaped organs that are located toward your back, on either side of your spine, just underneath your rib cage. Each kidney is about the size of your fist.
Your kidneys have many jobs, but their main job is to clean your blood, getting rid of toxins, waste and excess water as urine (pee). Your kidneys also balance the amount of electrolytes (such as salt and potassium) and minerals in your body, make hormones that control blood pressure, make red blood cells and keep your bones strong. If your kidneys are damaged and don’t work as they should, wastes can build up in your blood and make you sick.
How common is this condition?
About 15% of adults in the United States have chronic kidney disease. Some 37 million people in the U.S. are living with chronic kidney disease.
