WHY DIASTOLIC IS HIGH

The common perception is that the systolic blood pressure is more important than the diastolic blood pressure. While systolic blood pressure is vital, diastolic blood pressure holds equal importance for heart health. A consistently higher than normal diastolic blood pressure is a condition called diastolic hypertension, and it can increase the risk of heart disease. It is crucial to understand the causes and potential consequences of elevated diastolic blood pressure to manage this condition effectively.

Defining Diastolic Blood Pressure
Blood pressure is the force exerted by blood against the artery walls. It is measured in millimeters of mercury (mmHg) and has two components: systolic blood pressure and diastolic blood pressure. Systolic blood pressure is the pressure when the heart beats and pumps blood, while diastolic blood pressure is the pressure when the heart relaxes and fills with blood. Normal diastolic blood pressure should be below 80 mmHg.

Causes of High Diastolic Blood Pressure
Diastolic hypertension can be caused by several factors, including:

• Increased Blood Volume: This can occur due to conditions like kidney disease, which impairs the body’s ability to regulate fluid balance, resulting in excess fluid retention and elevated blood pressure.
• Heart Problems: Conditions such as aortic stenosis, where the aortic valve narrows, can obstruct blood flow, leading to increased pressure in the arteries.
• Arterial Stiffness: As we age, our arteries naturally become less flexible, which can increase diastolic blood pressure.
• Medications: Certain medications, such as decongestants and nonsteroidal anti-inflammatory drugs (NSAIDs), can temporarily increase diastolic blood pressure.
• Sleep Apnea: This condition, where breathing repeatedly stops and starts during sleep, can cause high diastolic blood pressure.

Consequences of High Diastolic Blood Pressure
Elevated diastolic blood pressure can lead to serious health complications, such as:

• Heart Attack: Prolonged high diastolic blood pressure can weaken the heart muscle, making it more susceptible to a heart attack.
• Stroke: High diastolic blood pressure can damage blood vessels in the brain, increasing the risk of a stroke.
• Kidney Disease: Diastolic hypertension can strain the kidneys, leading to kidney damage and potentially kidney failure.
• Heart Failure: Chronic high diastolic blood pressure can cause the heart to enlarge and weaken, eventually leading to heart failure.

Managing Diastolic Hypertension
Controlling diastolic hypertension requires a multifaceted approach, including:

• Lifestyle Modifications: Maintaining a healthy weight, engaging in regular physical activity, and adopting a balanced diet can significantly lower blood pressure.
• Medication: If lifestyle changes are insufficient, medications like diuretics, beta-blockers, and ACE inhibitors may be prescribed to manage diastolic blood pressure.
• Treating Underlying Conditions: Addressing underlying medical conditions that contribute to high diastolic blood pressure, such as kidney disease or sleep apnea, can help lower blood pressure.

Conclusion
Diastolic blood pressure is an essential indicator of heart health. Consistently high diastolic blood pressure can lead to severe complications. Understanding the causes and consequences of diastolic hypertension is crucial for managing this condition effectively. By implementing lifestyle changes, following prescribed medications, and addressing underlying medical conditions, individuals can effectively control diastolic hypertension and reduce their risk of heart disease.
