A diastolic blood pressure reading of 90 or greater indicates hypertension according to established medical guidelines. Hypertension is defined as a condition where blood pressure readings are consistently higher than normal. The normal range for diastolic blood pressure is less than 80 mmHg, with readings from 80 to 89 considered elevated or stage 1 hypertension depending on the context and patient health.

When diastolic blood pressure reaches 90 mmHg or higher, it signifies a significant risk factor for cardiovascular disease, as it indicates that the blood vessels are under excessive pressure during the relaxation phase of the heart cycle. This prolonged elevated pressure can lead to long-term health issues, including heart disease, stroke, and other cardiovascular complications.

Readings of 100 or greater indicate a more severe level of hypertension, often categorized as stage 2 or higher, but the primary threshold indicating hypertension begins at 90 mmHg. Thus, a reading of 90 or greater clearly identifies the onset of hypertension.
