THURSDAY, May 22 (HealthDay News) -- More than 100 million Americans should be monitoring their blood pressure at home, according to three major health organizations that are issuing recommendations on what to do and how to do it.

"We have an estimated 72 million [people] with hypertension [high blood pressure] and another 25 million with pre-hypertension," said Dr. Suzanne Oparil, professor of medicine at the University of Alabama at Birmingham.
