What blood pressure readings classify as "prehypertension" in adults?

The classification of blood pressure readings is essential for identifying an individual's risk for hypertension and cardiovascular diseases. Prehypertension serves as a warning sign that blood pressure levels are above the normal range but not yet high enough to be classified as hypertension.

A systolic reading of 120-139 mmHg combined with a diastolic reading of 80-89 mmHg fits the definition of prehypertension. These ranges are significant because they indicate that while blood pressure is not yet at the hypertensive level, it is elevated, and individuals in this category may benefit from lifestyle modifications to prevent progression to hypertension.

The threshold established by health care organizations, such as the American Heart Association, makes it clear that these specific readings denote an increased risk for developing high blood pressure in the future. Monitoring and potential preventive measures become a focus for individuals with these readings, informing health professionals about necessary interventions to promote cardiovascular health.
