Hypertension, also called high blood pressure, is the pressure of blood pushing against the walls of your arteries. Arteries carry blood from your heart to other parts of your body. Blood pressure normally rises and falls throughout the day, but it can damage your heart and cause health problems if it stays high for a long time.
High blood pressure is called the “silent killer” because many people don’t realize they have it. High blood pressure often has no warning signs or symptoms. The only way to detect whether or not you have high blood pressure is to have your blood pressure measured by a doctor or health professional — it is quick and painless.
