What causes kidney failure?

In most cases, kidney failure is caused by other health problems that have done permanent damage (harm) to your kidneys little by little, over time.

When your kidneys are damaged, they may not work as well as they should. If the damage to your kidneys continues to get worse and your kidneys are less and less able to do their job, you have chronic kidney disease. Kidney failure is the last (most severe) stage of chronic kidney disease. This is why kidney failure is also called end-stage renal disease, or ESRD for short.

Diabetes is the most common cause of ESRD. High blood pressure is the second most common cause of ESRD. Other problems that can cause kidney failure include:

Sometimes the kidneys can stop working very suddenly (within two days). This type of kidney failure is called acute kidney injury or acute renal failure. Common causes of acute renal failure include:

  • Heart attack
  • Illegal drug use and drug abuse
  • Not enough blood flowing to the kidneys
  • Urinary tract problems

This type of kidney failure is not always permanent. Your kidneys may go back to normal or almost normal with treatment and if you do not have other serious health problems.

Having one of the health problems that can lead to kidney failure does not mean that you will definitely have kidney failure. Living a healthy lifestyle and working with your doctor to control these health problems can help your kidneys work for as long as possible.

What are the treatment options for kidney failure?

If you have kidney failure (end-stage renal disease or ESRD), you will need dialysis or a kidney transplant to live. There is no cure for ESRD, but many people live long lives while on dialysis or after having a kidney transplant.

There are just a few options for treating kidney failure, including kidney transplant and several types of dialysis. Your doctor can help you figure out which treatment is best for you. Learn more about the treatment options for kidney failure.

What are the complications of kidney failure?

Your kidneys do many jobs to keep you healthy. Cleaning your blood is only one of their jobs. They also control chemicals and fluids in your body, help control your blood pressure and help make red blood cells. Dialysis can do only some, not all, of the jobs that healthy kidneys do. Therefore, even when you are being treated for kidney failure, you may have some problems that come from having kidneys that don’t work well. Learn more about the complications of kidney failure.

What should I eat when I have Kidney failure?

Dialysis helps to do some of the work that your kidneys did when they were healthy, but it cannot do everything that healthy kidneys do. Therefore, even when you are on dialysis, you will need to limit what and how much you eat and drink. Your diet needs may depend on the type of dialysis you are on (hemodialysis or peritoneal dialysis) and your treatment schedule. Learn more about the diet for living with kidney failure.

Learn what healthy eating means for people in every stage of kidney disease, including those on dialysis or living with a kidney transplant. Find recipes on Kidney Kitchen.
