The ranges are:
Normal: Less than 120 over 80 (120/80)
Prehypertension: 120-139 over 80-89.
Stage 1 high blood pressure: 140-159 over 90-99.
Stage 2 high blood pressure: 160 and above over 100 and above.
High blood pressure in people over age 60: 150 and above over 90 and above.
High blood pressure (HBP) itself usually has no signs or symptoms. Rarely,
headaches may occur.
You can have HBP for years without knowing it. During this time, the condition can damage your heart, blood vessels, kidneys, and other parts of your body.
Some people only learn that they have HBP after the damage has caused problems, such as
coronary heart disease,
stroke, or kidney failure.
Knowing your blood pressure numbers is important, even when you're feeling fine. If your blood pressure is normal, you can work with your health care team to keep it that way. If your blood pressure is too high, you can take steps to lower it. Lowering your blood pressure will help reduce your risk for related health problems.
