Blood Pressure Chart

Understanding your blood pressure readings is crucial for maintaining good health. These blood pressure categories are defined by the American Heart Association (AHA)1 and are widely accepted by healthcare professionals worldwide. Use these charts as a general guide, but always consult your healthcare provider for personalized advice.

Blood Pressure Categories

Note: You only need to meet ONE of the conditions (either systolic OR diastolic) to fall into a category. For example, if your systolic pressure is 135 (Stage 1) but your diastolic is 75 (Normal), you would still be classified in the Stage 1 Hypertension category.

Blood Pressure Category Systolic (mm Hg) Diastolic (mm Hg)
Normal Less than 120 Less than 80
Elevated 120-129 Less than 80
High Blood Pressure (Stage 1) 130-139 80-89
High Blood Pressure (Stage 2) 140 or higher 90 or higher
Hypertensive Crisis Higher than 180 Higher than 120

When to Take Action

  • Normal: Maintain healthy lifestyle habits
  • Elevated: Consider lifestyle modifications
  • Stage 1: Consult healthcare provider about lifestyle changes and possible medication
  • Stage 2: Consult healthcare provider about medication and lifestyle changes
  • Crisis: Seek immediate emergency medical attention

Factors Affecting Blood Pressure

  • Age: Blood pressure typically increases with age due to reduced artery flexibility
  • Gender: Risk patterns differ between men and women at different life stages
  • Physical activity: Regular exercise helps maintain healthy blood pressure
  • Diet: Especially salt intake, processed foods, and alcohol consumption
  • Stress levels: Both acute and chronic stress can impact blood pressure
  • Underlying health conditions: Such as kidney disease, diabetes, or thyroid problems
  • Genetics: Family history can influence your risk of high blood pressure
  • Medications: Some medications can affect blood pressure readings

1 Blood pressure guidelines have evolved over time based on extensive medical research. The current categories were updated in 2017 when the AHA and the American College of Cardiology (ACC) lowered the threshold for high blood pressure to 130/80 mm Hg from the previous 140/90 mm Hg. This change was made to encourage earlier intervention and prevent heart disease. ↩
