Common causes of CKD
Some people are more at risk of getting CKD. People who are in the higher risk group include those who:
- have high blood pressure
- are an unhealthy weight
- smoke
- have diabetes
- have heart disease
- have a family history of kidney disease
- are Māori or Pasifika
- are 60 or older.
If you or a member of your family are in one of these groups, talk to your doctor about being tested for kidney problems. Also find out what you can do to keep them healthy and functioning well.
The two most common causes of kidney disease are diabetes and high blood pressure.
Diabetes
When your blood sugar is raised, it causes damage to many blood vessels in your body, including the blood vessels in your kidneys.
About one in three people with diabetes will end up with some kidney damage.
Kidney disease caused by diabetes is called diabetic nephropathy.
Read more about diabetes & kidney disease.
High blood pressure
High blood pressure damages the small vessels that take blood to the kidney filters and can also damage the filters themselves.

Other causes
- Kidney inflammation called glomerulonephritis is a group of diseases that affects the filtering units in your kidneys.
- Polycystic kidney disease causes cysts to form in your kidneys. This is an inherited disease, which means it's passed down from your parents.
- Lupus and other diseases that affect your body’s immune system can also affect your kidneys.
- Obstructions or blockages in the flow of urine caused by kidney stones or an enlarged prostate gland can affect your kidneys.
- Urinary reflux where the urine flows back from your bladder to your kidneys can cause scarring in your kidneys.
- Repeated kidney infections can lead to long-term kidney problems.
- Long term regular use of pain-relieving medicines called anti-inflammatories (NSAIDS) can harm your kidneys.
