What defines Stage 1 hypertension?

Stage 1 hypertension is defined by blood pressure readings that fall within the range of 140/90 mmHg to 159/99 mmHg. This classification is important as it helps healthcare providers identify individuals who may need lifestyle modifications or early intervention to prevent progression to more severe hypertension.

The systolic measurement of 140 mmHg or higher indicates that the pressure in the arteries during heartbeats is elevated, while the diastolic measurement of 90 mmHg or higher reflects an elevated pressure in the arteries during the resting phase between heartbeats. Identifying Stage 1 hypertension allows for the implementation of preventive measures, such as diet, exercise, and sometimes medication, to manage blood pressure and reduce the risk of cardiovascular disease.

The other ranges provided do not fit the criteria for Stage 1 hypertension. For example, values below this range (like 120/80-139/89) indicate normal or elevated blood pressure without reaching the threshold of hypertension, whereas higher values (160/100-179/109) represent Stage 2 hypertension, and 180/120 mmHg and above classify as hypertensive crisis, requiring immediate medical attention.
