Diastolic pressure

Diastolic pressure is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen. This is what you feel as a pulse.

Overview

Diastolic pressure is the bottom number in a blood pressure reading. For example, if your reading is 120/80, your diastolic blood pressure is 80. This number is considered normal. A diastolic blood pressure between 80 and 89 is considered prehypertension. A diastolic blood pressure of 90 or higher is considered high (hypertension).

Importance

The diastolic pressure is important because it gives an indication of the pressure in your arteries when the heart is at rest. High diastolic pressure can lead to hypertension, which can cause heart disease and stroke.

Measurement

Diastolic pressure is measured using a device called a sphygmomanometer, which includes a cuff to constrict the artery and a manometer to measure the pressure. The pressure is measured in millimeters of mercury (mmHg).

Factors affecting diastolic pressure

Several factors can affect your diastolic pressure, including:

• Age: Diastolic pressure tends to decrease after age 55.
• Physical activity: Regular physical activity can help lower your diastolic pressure.
• Diet: A diet high in salt can increase your diastolic pressure.
• Alcohol and tobacco: Both can raise your diastolic pressure.
• Stress: Long-term stress can increase your diastolic pressure.

Treatment

Treatment for high diastolic pressure may include lifestyle changes such as diet and exercise, and medication. It's important to work with your doctor to manage your diastolic pressure.
