What is considered a normal diastolic blood pressure?

Diastolic blood pressure, which is the lower number in a blood pressure reading, varies in its ideal range depending on an individual's age, health status, and clinical condition.

For healthy adults aged 18 years or older, the ideal range for diastolic blood pressure is between 60mmHg and 89mmHg. Younger individuals without underlying medical conditions should aim to maintain diastolic blood pressure below 80mmHg. Patients who already suffer from chronic conditions such as coronary artery disease, diabetes, or renal insufficiency are also advised to keep diastolic blood pressure as low as possible below 80mmHg to reduce the burden on the heart and the systemic vascular system.

Blood pressure is a dynamic physiological parameter influenced by multiple external and internal factors, including but not limited to emotional changes, intensity of physical activity, dietary habits, and medication use. Therefore, when measuring blood pressure, it is important to be in a relatively relaxed and calm state, and it is recommended to take multiple readings under resting conditions to obtain more stable and accurate blood pressure values.
