Why are the kidneys so important to good health?

Your kidneys do some important jobs to keep your body healthy. They:
  • Balance your body fluids. Excess fluid is filtered out of your blood, and it leaves your body as urine. Your kidneys make about one to two quarts of urine a day.
  • Regulate body water and important minerals in your blood, such as sodium, potassium, phosphorus and calcium.
  • Remove waste products from your blood. These waste products come from the breakdown of foods you eat and from normal muscle activity.
  • Remove drugs and toxins from your body.
  • Release hormones into your blood, which control blood pressure, make red blood cells and keep your bones healthy.
