The one health number most people over 40 never check

High blood pressure has no symptoms. A cuff at home is the simplest way to know where you stand.

Roughly half of adults with high blood pressure do not know they have it. It causes no symptoms until it causes a stroke or heart attack, and a single reading at the doctor's office can be misleading in either direction.
