High Blood Pressure
High blood pressure is the force of blood pushing against the walls of your arteries, which carry the blood from your heart to other parts of your body. Throughout the day, your blood pressure normally rises and falls, however, if it stays high for a long period of time, it has the potential to damage your heart and may even lead to health problems. High blood pressure raises your risk for heart disease and stroke, which are leading causes of death in the United States.
High blood pressure is also known as the "Silent Killer" because it has no warning signs or symptoms, and many people don't even know they have it. The only way to know if you have it is by measuring your blood pressure and visiting your physician. Once it is identified, then you can take the proper steps to control it if it is too high.
