High blood pressure is often called the silent killer. You might not have symptoms, but it’s a leading risk factor for heart disease and stroke. Monitoring your own blood pressure at home can help you keep your blood pressure under control.
Hypertension increases your risk for heart disease and stroke. The good news is that there are steps you can take every day to keep your blood pressure in a healthy range.
What is Normal Blood Pressure?
A blood pressure reading has a top number (systolic) and bottom number (diastolic). Normal blood pressure is less than 120 over 80 (120/80). People whose blood pressure is above the normal range should ask their doctor how to lower it.
What are the symptoms when your blood pressure is high?
A few people with high blood pressure may have headaches, shortness of breath or nosebleeds, but these signs and symptoms aren’t specific and usually don’t occur until high blood pressure has reached a severe or life-threatening stage.
What is dangerously high blood pressure?
A hypertensive crisis is a severe increase in blood pressure that can lead to a stroke. Extremely high blood pressure — a top number (systolic pressure) of 180 millimeters of mercury (mm Hg) or higher or a bottom number (diastolic pressure) of 120 mm Hg or higher — can damage blood vessels.
