Does this describe your symptoms?

Definition
  • Systolic blood pressure greater than 140 or
  • Diastolic blood pressure greater than 90 or
  • Taking medications for high blood pressure

General Information

  • Systolic vs Diastolic: The blood pressure (BP) reading is written as two numbers, the systolic pressure and the diastolic pressure. For example, if a person had a BP of 130/65, then 130 would be the systolic blood pressure and 65 would be the diastolic blood pressure.
  • Definition of High Blood Pressure: An adult has hypertension (high blood pressure) if the blood pressure (BP) readings consistently show a BP greater than 140/90, that is, a systolic BP over 140 OR a diastolic BP over 90.
  • Untreated hypertension may cause damage to the heart, brain, kidneys, and eyes.
  • Automatic home BP measurement devices can sometimes be unreliable. You should check your BP in both arms. If there is another adult in the home, consider checking his/her BP to see if the device is functioning correctly. If there is any doubt, go in to your doctor's office to get your blood pressure checked.
