What causes kidney disease?

2-minute read

There are many different things that can cause problems with the kidneys. Causes of kidney disease include physical injury, infection, cysts in the kidneys, the backward flow of urine from the bladder, or hereditary causes. The kidneys can also be damaged by misuse of some pain killers and legal and illegal drugs.

What are the most common causes of kidney disease?

The most common cause of kidney disease in Australia is diabetes. This is sometimes called diabetic nephropathy. About 1 in 3 of all people with diabetes develop kidney disease when high blood sugar levels damage the blood vessels in the kidneys, stopping them from filtering wastes properly.

High blood pressure can also lead to kidney disease. So can glomerulonephritis, which is an inflammation of the kidneys that can be inherited or can follow an infection.

Risk factors for kidney disease

Some people are more likely to get kidney disease than others. You are more likely to get kidney disease if you:

  • have diabetes
  • have high blood pressure
  • have heart failure, or have had a heart attack or stroke
  • have kidney disease in the family
  • are very overweight
  • smoke
  • are 60 years or older
  • are of Aboriginal or Torres Strait Islander origin
  • have injured a kidney in the past

Even if one or more of these things applies to you, there are many things you can do help manage your risk of kidney disease. See preventing kidney disease.
