Did You Know?
You might have thought that hypertension was what a movie audience feels near the climax of a thriller, but you would have been wrong. High blood pressure—that is high pressure against the walls of your veins and arteries caused by blood flow—often occurs when the arteries or veins become blocked or narrowed, making the heart work harder to pump blood. But many cases seem to be the result of smoking or taking in too much salt, and many are genetically caused. Hypertension is serious, since it can lead to heart attacks and strokes. Though it often produces no warning symptoms, your blood pressure can be checked quickly and easily by a nurse. If it's high, it can usually be controlled by stopping smoking, losing weight, lowering your salt intake, and exercising—and if all else fails, by medication.

Medical Definition of hypertension
1: abnormally high arterial blood pressure that is usually indicated by an adult systolic blood pressure of 140 mm Hg or greater or a diastolic blood pressure of 90 mm Hg or greater, is chiefly of unknown cause but may be attributable to a preexisting condition (as a renal or endocrine disorder), that typically results in a thickening and inelasticity of arterial walls and hypertrophy of the left heart ventricle, and that is a risk factor for various pathological conditions or events (as heart attack, heart failure, stroke, end-stage renal disease, or retinal hemorrhage)—see essential hypertension, secondary hypertension, white coat hypertension
2: a systemic condition resulting from hypertension that is either symptomless or is accompanied especially by dizziness, palpitations, fainting, or headache
