Kidney disease & treatment

What are kidneys?

The kidneys are bean-shaped organs the size of your fist on the left and right sides of your spine. They filter out waste and extra fluid from your body.

Your 2 kidneys make urine (pee) and do many other jobs that keep you healthy, such as:

  • Balance your body’s water and salt levels, and make sure your body doesn’t get too acidic or basic
  • Clean waste from your body
  • Make hormones to help:
      • Control your blood pressure
      • Keep your bones healthy
      • Make red blood cells
