Causes
Atherosclerosis or Clogged Arteries
Renal artery disease is usually caused by atherosclerosis or clogged arteries. This happens when plaque, a material consisting of cholesterol and fats, builds up in them.
Muscle Disorder
In younger people, particularly women under the age of 40, the condition is often the result of a muscle disorder in which abnormal tissue grows in the renal artery and narrows it.
