What is the normal range for diastolic blood pressure?

Some individuals with hypertension routinely measure their blood pressure at home after waking up in the morning, and many notice that their diastolic (low) blood pressure readings are elevated. However, most people are unclear about the normal range for diastolic pressure. So, what is the normal range for diastolic blood pressure?

What Is the Normal Range for Diastolic Blood Pressure?

Diastolic pressure—the “low” number in a blood pressure reading—normally falls between 60 and 89 mmHg. Normal systolic (high) pressure ranges from 90 to 139 mmHg; hypertension is diagnosed when systolic pressure consistently exceeds 140 mmHg. If blood pressure remains persistently low but no symptoms are present, treatment may not be necessary at this time. However, if symptoms such as dizziness or weakness in the limbs occur, this may indicate constitutional weakness. In such cases, dietary improvements—such as consuming easily digestible, nutrient-rich foods—can help. Nevertheless, hypotension may also result from pathological conditions, including malignancy, massive hemorrhage, or decreased thyroid hormone levels. When hypotension stems from an underlying disease, it typically resolves once the primary condition is effectively treated.

With advancing age, atherosclerosis of the aorta reduces arterial elasticity, leading to lower diastolic pressure. In older adults, diminished vascular elasticity causes blood pressure to rise rapidly during cardiac ejection, resulting in a marked increase in systolic pressure.

In daily dietary choices, prioritize high-protein, vitamin- and trace-element–rich foods such as fish, shrimp, eggs, dairy products, and lean mutton. You may also consume nutritious soups daily. We hope this article has been helpful to you. Wishing you a joyful life and optimal health!
