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.
