A blood pressure reading of 140/70 mmHg is not considered normal. Blood pressure is measured in millimeters of mercury (mmHg) and is recorded as two numbers: systolic pressure (the higher number) and diastolic pressure (the lower number).
In the reading you provided:
- 140 mmHg represents the systolic pressure, which is the pressure in the arteries when the heart beats and pumps blood.
- 70 mmHg represents the diastolic pressure, which is the pressure in the arteries when the heart is at rest between beats.
The current guidelines for blood pressure categorization by the American Heart Association (AHA) are as follows:
- Normal: Less than 120/80 mmHg
- Elevated: 120-129/less than 80 mmHg
- Stage 1 hypertension: 130-139/80-89 mmHg
- Stage 2 hypertension: 140/90 mmHg or higher
Based on these guidelines, a blood pressure reading of 140/70 mmHg falls into the category of Stage 1 hypertension. It is essential to monitor blood pressure regularly and consult a healthcare professional to develop an appropriate management plan. Lifestyle changes, such as dietary modifications, exercise, and stress reduction, may be recommended, and in some cases, medication may be prescribed to help lower blood pressure.
