How is hypertension classified?

Hypertension is classified primarily based on the measurements of both systolic and diastolic blood pressure. The classification into Stage 1 and Stage 2 hypertension reflects increasing levels of blood pressure as defined by specific ranges. Stage 1 hypertension is generally identified with systolic readings between 130-139 mmHg or diastolic readings between 80-89 mmHg. Stage 2 hypertension is characterized by more severe readings, typically at or above 140 mmHg systolic or 90 mmHg diastolic. This dual consideration of both systolic and diastolic pressures is crucial because it provides a more comprehensive picture of a patient's cardiovascular risk and health status.

The other approaches to classifying hypertension, such as solely focusing on systolic or diastolic pressures, fail to capture the complexity and potential risks associated with high blood pressure. Additionally, using age and gender as a basis for classification does not conform to the medical standards in defining hypertension but rather corresponds to statistics that may influence risk assessments. Hence, the classification system based on systolic and diastolic pressures is essential for effective diagnosis and treatment of hypertension.
