More and more experts now recommend that people with high blood pressure regularly check their blood pressure at home. Doing this gives people an idea where their blood pressure stands in between office visits, and can motivate them to care more about their health. It also helps doctors make quick medication adjustments to keep blood pressure in the healthy zone.
