Diastolic Blood Pressure Range

In clinical medicine, diastolic blood pressure refers to the pressure exerted by blood against the arterial walls when the heart is at rest between beats. For adults, the generally accepted normal range of diastolic blood pressure is 60 mmHg to 89 mmHg. Diastolic blood pressure below 60 mmHg may be considered hypotension, while pressure above 90 mmHg may indicate a risk of hypertension.

Although 90 mmHg is regarded as the upper limit of diastolic blood pressure, if the diastolic pressure remains consistently at or above this level, further clinical evaluation is often required to determine whether a diagnosis of hypertension is appropriate. Furthermore, the ideal diastolic blood pressure range is generally considered to be between 70 mmHg and 80 mmHg, as this range helps reduce the risk of cardiovascular disease.

Diastolic blood pressure above 80 mmHg may indicate an increased risk of hypertension, and long-term hypertension can raise the incidence of cardiovascular and cerebrovascular diseases. If diastolic blood pressure is abnormal, timely medical consultation is recommended, along with following the treatment and lifestyle recommendations provided by a physician.
