The consequences of high blood pressure can be deadly, warns Dr. Bennett. “The No. 1 thing affected is your kidneys.” Over time the kidneys may shrink, ultimately leading to kidney failure.

Uncontrolled high blood pressure also can lead to dementia. “Most people equate dementia with Alzheimer’s, but Alzheimer’s is only one cause,” says Dr. Bennett. High blood pressure can affect the arteries in your brain, causing them to shut down.

Here are some lifestyle changes that can lower blood pressure:

• Maintain a healthy weight
• Cut down on salt
