Step 2: Take High Blood Pressure Seriously   Next Page

In individuals with high blood pressure, their blood pressure stays elevated all or most of the time. Their blood pushes against the walls of the arteries with a greater-than-normal force. If untreated, this can lead to serious medical problems. Click the red buttons below to learn more about these problems.

Effects on multiple organs -- It is important to realize that although high blood pressure may have no outward symptoms, it can cause problems with multiple organs. To see specific examples of how high blood pressure effects blood vessels, the heart, and the kidneys, click the red buttons over the picture above.

Atherosclerosis and stroke - videos

Thickening in the artery (atherosclerosis) related to high blood pressure can be dramatic. A healthy artery is wide and allows blood to flow freely. In contrast, a clogged artery is narrow, thick, and makes the heart work a lot harder to pump blood through it. Arteries anywhere in the body can be affected, including those to the heart itself and the brain.

Watch arteries supplying blood to the brain grow thicker and narrower.

Stroke is one of the most common causes of death in the U.S., and high blood pressure is a major risk factor. Clots that form in the carotid arteries (in the neck) or the heart can break off and travel to the brain, lodging in the narrowed arteries.
