High Blood Pressure

What Is High Blood Pressure?

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. When high blood pressure is not diagnosed and treated, it can lead to other life-threatening conditions, including heart attack, heart failure, stroke, and kidney failure. It can also lead to vision changes or blindness.
