Chronic kidney disease (CKD) is a long-term condition where the kidneys don't work as well as they should.
It's a common condition often associated with getting older. It can affect anyone, but it's more common in people who are black or of south Asian origin.
CKD can get worse over time and eventually the kidneys may stop working altogether, but this is uncommon. Many people with CKD are able to live long lives with the condition.

Chronic kidney disease is usually caused by other conditions that put a strain on the kidneys. Often it's the result of a combination of different problems.
CKD can be caused by:
You can help prevent CKD by making healthy lifestyle changes and ensuring any underlying conditions you have are well controlled.
CKD can be diagnosed using blood and urine tests. These tests look for high levels of certain substances in your blood and urine that are signs your kidneys aren't working properly.
If you're at a high risk of developing kidney disease (for example, you have a known risk factor such as high blood pressure or diabetes), you may be advised to have regular tests to check for CKD so it's found at an early stage.
The results of your blood and urine tests can be used to tell the stage of your kidney disease. This is a number that reflects how severe the damage to your kidneys is, with a higher number indicating more serious CKD.

There's no cure for CKD, but treatment can help relieve the symptoms and stop it getting worse.
Your treatment will depend on how severe your condition is.
The main treatments are:
You'll also be advised to have regular check-ups to monitor your condition.
CKD can range from a mild condition with no or few symptoms, to a very serious condition where the kidneys stop working, sometimes called kidney failure.
Most people with CKD will be able to control their condition with medicine and regular check-ups. CKD only progresses to kidney failure in around 1 in 50 people with the condition.
If you have CKD, even if it's mild, you're at an increased risk of developing other serious problems, such as cardiovascular disease. This is a group of conditions affecting the heart and blood vessels, which includes heart attack and stroke.
Cardiovascular disease is one of the main causes of death in people with kidney disease, although healthy lifestyle changes and medicine can help reduce your risk of developing it.
