Irwin has prehypertension, which is defined as D) SBP range of 120-139 and DBP range of 80-89.
This condition is identified when one's systolic blood pressure is between 120 and 139 mm Hg and diastolic blood pressure is between 80 and 89 mm Hg.
Prehypertension is a way to identify individuals at high risk for developing hypertension, which is characterized by more consistently elevated blood pressure readings.
