What is the blood pressure range for prehypertension?

The blood pressure range for prehypertension is generally defined as a systolic pressure of 120-139 mmHg and a diastolic pressure of 80-89 mmHg. This classification indicates a condition where blood pressure is elevated above normal levels but not yet high enough to be classified as hypertension. It serves as a warning sign, prompting individuals to adopt lifestyle changes to prevent progression to hypertension, which can lead to more serious health issues such as heart disease and stroke.

The provided range encompasses the upper limits of what is considered normal and the lower limits of stage 1 hypertension. This understanding is crucial for gerontological nutritionists, as they can implement dietary recommendations and lifestyle modifications to help manage and potentially lower blood pressure in older adults, thereby improving their overall health outcomes.
