Both aorta examples come from people around age 45. In the healthy aorta (left), the tissue is supple and the kidneys are nice and plump. But, in the second example (right), Dr. Oz points out plaque along the aorta. This plaque shows early signs of serious disease.
Eventually, if the disease worsens, a patient's kidney can become shriveled, and he or she may need a replacement. The aorta may also develop aorta chips, which are caused by plaque buildup.
"Plaque is just the first step," Dr. Oz says. "It's your warning sign—like someone saying, 'Help me!' And you've got to listen to that call because it will become like this [unhealthy aorta] and by the time it gets this far along, often there's been too much damage done."
