High Blood Pressure

High blood pressure, also known as hypertension, is often called a 'silent killer.' Many people don’t know that they have it because it often has no warning signs or symptoms. The only way to know if you have hypertension is to measure your blood pressure. If you have high blood pressure, your doctor may prescribe medications for you to take.

Blood pressure is measured using two numbers — systolic and diastolic:


  • Systolic: <120 mmHg
  • Diastolic: <80 mmHg

At risk:

  • Systolic: 120–139 mmHg
  • Diastolic: 80–89 mmHg


  • Systolic: 140+ mmHg
  • Diastolic: 90+ mmHg

Check with your doctor to know if your blood pressure is within a safe range.
