A condition in which the force of the blood against the artery walls is too high.
Usually hypertension is defined as blood pressure
above 140/90, and is considered severe
if the pressure is above 180/120.
High blood pressure often has no symptoms. Over time, if untreated
it can cause health conditions, such as heart disease and stroke.
Eating a healthier diet with less salt
and taking medication can help lower blood pressure.
