Hypertension, or high blood pressure, is a condition in which blood consistently moves through arteries with too much force. A blood pressure measurement has two components: systolic blood pressure (the pressure as blood is pumping out of the heart) and diastolic blood pressure (the pressure as your heart rests between beats). If you have hypertension, your systolic blood pressure will be higher than 130 mm HG, or your diastolic blood pressure will be higher than 80 mm Hg. The condition doesn’t usually come with symptoms, but it can lead to life-threatening problems like stroke, heart attack, and dementia. Lifestyle changes and professional treatment can often help to lower blood pressure.
