What is the primary requirement to diagnose hypertension?

To accurately diagnose hypertension, two or more elevated blood pressure readings taken on separate occasions are necessary. This requirement is in place to ensure that temporary fluctuations or isolated elevated readings do not lead to a misdiagnosis. Blood pressure can be influenced by various factors, including stress, physical activity, or even meals, which means a single reading may not reflect a person's usual blood pressure status.

Consistent elevations across multiple assessments provide a more reliable indication of hypertension. Diagnosis is supported by the repeated readings that meet established criteria, typically defined as a systolic blood pressure of 130 mmHg or higher, or a diastolic blood pressure of 80 mmHg or higher. This careful approach helps healthcare providers determine if a patient truly has a chronic condition that requires management and intervention.
