You would know if you were experiencing high blood pressure, right? Wrong. High blood pressure, also called HBP or hypertension, is actually a largely symptomless condition. If the force of your blood flow is too high, and the heart is being forced to pump harder than it should, the tissue that makes up the walls of the arteries is stretched beyond its healthy limit, causing damage. The strain on the body can lead to a stroke, heart attack or chronic kidney disease.
