Almost half of Americans have high blood pressure, according to AHA

Forty-six percent of Americans have high blood pressure, according to the American Heart Association.
That number is almost half of all Americans!
New guidelines define normal as less than 120 over 80.
Sometimes a change of lifestyle, such as losing weight, quitting smoking, limiting alcohol and exercising, can help.
Blood pressure should be checked at least once a year by a health professional.
