There are many causes of kidney disease, which represents a growing health-care problem in Canada. The two main causes of kidney disease in Canada are diabetes and high blood pressure.

Other common causes include:

  • vascular disease which is a hardening of the arteries
  • glomerulonephritis, the inflammation of the kidney filtering units
  • polycystic kidney disease (cysts in the kidney)
  • drug-induced kidney failure
  • pyelonephritis which is an infection in the kidney
  • blockage of the flow of urine , also called a urinary tract obstruction
  • other rare genetic diseases
