​Why diastolic blood pressure matters and how to keep it under control​

An ideal blood pressure is 120/80 which is spelt as 120 over 80. In a blood pressure reading, 120 is systolic and 80 is diastolic. Diastolic blood pressure (DBP) is a critical component of blood pressure readings, representing the pressure in the arteries when the heart is at rest between beats. While systolic blood pressure (SBP) measures the force when the heart contracts and pumps blood into the arteries, diastolic pressure reflects the arterial pressure during the heart's relaxation phase. Here are several reasons why diastolic blood pressure matters and why you should not ignore an elevated diastolic reading:

Diastolic blood pressure is a key indicator of the heart's ability to relax and fill with blood. Elevated diastolic pressure can signify stiffness in the arteries, making it more challenging for the heart to receive an adequate supply of blood during its resting phase. This increased workload on the heart can contribute to various cardiovascular issues.

Diastolic blood pressure is crucial for coronary perfusion, the process by which the coronary arteries supply blood to the heart muscle. If diastolic pressure is too low, the heart may not receive sufficient blood supply during its resting phase, potentially leading to coronary artery disease and other heart-related complications. Adequate diastolic pressure is vital for perfusing other organs, ensuring they receive a continuous supply of oxygen and nutrients. Insufficient diastolic pressure can impact organ function and contribute to conditions such as kidney disease.

Prolonged elevation of diastolic blood pressure can lead to damage in various organs, including the heart, kidneys, and blood vessels. This damage may manifest as heart failure, chronic kidney disease, or vascular issues, emphasizing the importance of maintaining healthy diastolic pressure levels.

Several factors can contribute to an increase in diastolic blood pressure. Common causes include heightened stress levels, excessive salt intake, obesity, sedentary lifestyle, and aging. Conditions such as diabetes, kidney disease, and hormonal imbalances may also impact diastolic pressure. Additionally, smoking, excessive alcohol consumption, and certain medications can elevate diastolic blood pressure. Regular monitoring and consultation with healthcare professionals help identify and manage underlying causes of elevated diastolic blood pressure.

A healthy and active lifestyle can keep the diastolic blood pressure under control. Engage in moderate-intensity aerobic exercise for at least 150 minutes per week. Activities like brisk walking, cycling, or swimming can help lower both systolic and diastolic blood pressure. Adopt a heart-healthy diet rich in fruits, vegetables, whole grains, lean proteins, and low-fat dairy. Reduce sodium intake by avoiding processed foods, canned goods, and restaurant/fast food. Keep track of your blood pressure at home, and regularly check in with your healthcare provider. Understanding your blood pressure trends can help you and your doctor make informed decisions about your treatment plan.
