High Blood Pressure (Hypertension) High blood pressure, or
hypertension, is a condition in which the force of blood against
artery walls is too strong. Over time, high blood pressure can
damage the arteries, heart, and kidneys and can lead to heart
disease and stroke. High blood pressure can be treated
effectively with lifestyle changes and medicines that can reduce
the risk of complications. Blood pressure readings consist of an
upper number and a lower number (such as 120 over 90 or 120/90).
The upper number is systolic blood pressure. The lower number is
diastolic blood pressure. Blood pressure readings are measured
in units called millimeters of mercury (mm Hg). Normal blood
pressure is 119 mm Hg systolic over 79 mm Hg diastolic or below.
