High blood pressure, also called hypertension, is when blood flows through your arteries with excessive force or pressure. This causes your blood pressure to measure consistently above normal. High blood pressure is considered to be 130⁄80 mm Hg. Having high blood pressure can be harmful to your health. Over time the excessive force on your arteries can damage your organs including your heart, kidneys, and brain. High blood pressure typically doesn’t have symptoms which is why it’s so important to get your blood pressure regularly checked by your doctor. If your blood pressure is dangerously high you may have shortness of breath, headaches, nosebleeds, chest pain or dizziness. Obesity, diabetes and smoking can all increase your risk for developing high blood pressure.
