What are the Causes of Kidney Failure?

Q:
What are the causes of kidney failure?

A:
Kidney failure occurs when the kidneys partly or completely lose their ability to filter water and waste from the blood. The build-up of toxic substances can cause dangerous health problems.

Two kinds of kidney failure are acute kidney failure and chronic kidney failure.

Acute kidney failure (also referred to as renal failure) can happen rapidly. Its causes include:

  • blood flow slowly to your kidneys
  • direct damage to your kidneys
  • kidneys’ urine drainage tubes (ureters) become blocked and wastes can’t leave your body

Chronic kidney disease, also called chronic kidney failure, describes the gradual loss of kidney function. Its causes include:
 a disease or condition impairs kidney function

In most cases, progressive kidney damage is the result of a chronic disease or other factors, such as

  • Diabetes
  • High blood pressure
  • Heart and blood vessel (cardiovascular) disease
  • Smoking
  • Obesity
  • Being African-American, Native American or Asian-American
  • Family history of kidney disease
  • Abnormal kidney structure
  • Older ageIf you have had some early or possible signs of kidney failure, we advise that you turn to your doctor as soon as possible and have yourself checked up.
