Renal Artery Disease
Renal artery disease is the narrowing of one or both of the
arteries that supply blood to the kidneys.
When the arteries that carry blood to your kidneys become narrow,
less blood flows to the kidneys. The kidneys mistakenly respond
as if your blood pressure is low and give off hormones that tell
the body to hold on to more salt and water. This causes your
blood pressure to rise.
Usually, high blood pressure causes no symptoms. Occasionally you
may have a mild headache. If your headache is severe, or if you
have any of the symptoms below, see a doctor right away. These

- Crushing, angina-like
