What defines prehypertension in blood pressure measurements?

Prehypertension is a term used to describe blood pressure values that are elevated but do not meet the criteria for hypertension. The correct range for prehypertension is specifically identified as having systolic blood pressure between 120-139 mm Hg and diastolic blood pressure between 80-89 mm Hg. This classification indicates that the individual is at an increased risk for developing hypertension in the future and is often a signal to make lifestyle changes to reduce that risk.

Understanding this classification is important in clinical practice as it helps healthcare providers identify patients who may benefit from interventions aimed at lifestyle modifications, such as dietary changes, increased physical activity, and other preventive measures, to lower their blood pressure and improve overall health.
