High blood pressure is often called "the silent killer" because it usually has no symptoms. Occasionally, headaches may occur. Some people may not find out they have high blood pressure until they have trouble with their heart, kidneys, or eyes.

What Is High Blood Pressure?

Blood pressure is the force of blood pushing against the walls of the blood vessels as the heart pumps blood. If your blood pressure rises and stays high over time, it’s called high blood pressure. High blood pressure is dangerous because it makes the heart work too hard, and the high force of the blood flow can harm arteries and organs such as the heart, kidneys, brain, and eyes.
