As of Monday, 30 million more Americans now suffer from high blood pressure. The findings mean that an additional 14% of US adults, or about 30 million people, will now be diagnosed with high blood pressure, bringing the total number to 100 million people living with the condition in the U.S.

Though more people will need treatment, Jarvis says most of those newly defined as having high blood pressure will not need medication. But only a small percentage of those patients will be prescribed anti-hypertensive medication, the association said. Now 103 million people will have high blood pressure.
