What Is a Normal Blood Pressure?

March 9, 2024

A normal blood pressure reading is typically defined as having a systolic pressure (the top number) below 120 mm Hg and a diastolic pressure (the bottom number) below 80 mm Hg. This is often expressed as 120/80 mm Hg.

However, blood pressure can vary throughout the day and can be influenced by factors such as activity level, stress, and diet. It’s essential to consider individual circumstances and any existing health conditions when interpreting blood pressure readings.

Here’s a general guide to blood pressure categories:

  1. Normal: Systolic less than 120 mm Hg and diastolic less than 80 mm Hg (120/80 mm Hg).
  2. Elevated: Systolic between 120-129 mm Hg and diastolic less than 80 mm Hg.
  3. Hypertension Stage 1: Systolic between 130-139 mm Hg or diastolic between 80-89 mm Hg.
  4. Hypertension Stage 2: Systolic 140 mm Hg or higher or diastolic 90 mm Hg or higher.
  5. Hypertensive Crisis: Systolic higher than 180 mm Hg and/or diastolic higher than 120 mm Hg. Immediate medical attention is required.

It’s important to regularly monitor blood pressure and consult with a healthcare professional to determine an appropriate course of action if readings consistently fall outside the normal range. Maintaining a healthy lifestyle, including regular exercise, a balanced diet, limiting alcohol intake, managing stress, and avoiding tobacco use, can help maintain normal blood pressure levels and reduce the risk of hypertension-related complications.
