The kidneys are a pair of organs that filter waste materials out of the blood.
The waste is passed out out of the body as urine. Kidneys produce important hormones
and regulate blood pressure and the levels of water, salts, and minerals in the body.
Kidney damage can occur in someone who has had diabetes for many years, especially
if the diabetes isn't controlled. You'll find your kidneys on either side of your
spine, just below the rib cage.
