What is the difference between systolic and diastolic blood pressure?
+
Systolic blood pressure is the pressure in the arteries when the heart beats and pumps blood, while diastolic blood pressure is the pressure in the arteries when the heart is resting between beats.
What are considered normal systolic and diastolic blood pressure readings?
+
Normal blood pressure is typically around 120 mm Hg systolic and 80 mm Hg diastolic, often expressed as 120/80 mm Hg.
Why is high systolic blood pressure a concern?
+
High systolic blood pressure can indicate increased risk for cardiovascular diseases, such as heart attack and stroke, because it reflects the force the heart has to exert to pump blood.
Can diastolic blood pressure be too low, and what does that mean?
+
Yes, very low diastolic blood pressure can reduce the amount of oxygen-rich blood reaching the heart and other organs, potentially causing dizziness or fainting.
How do systolic and diastolic blood pressure values change with age?
+
Systolic pressure tends to increase with age due to stiffening of arteries, while diastolic pressure may remain stable or even decrease in older adults.
What lifestyle changes can help maintain healthy systolic and diastolic blood pressure?
+
Regular exercise, a balanced diet low in salt, maintaining a healthy weight, limiting alcohol, and managing stress can help maintain healthy blood pressure levels.
How are systolic and diastolic blood pressure measured?
+
Blood pressure is measured using a sphygmomanometer, which inflates a cuff around the arm and listens for blood flow sounds to determine systolic and diastolic pressures.
What does it mean if only systolic blood pressure is high but diastolic is normal?
+
This condition, called isolated systolic hypertension, is common in older adults and can still increase the risk of cardiovascular problems.
Can stress affect systolic and diastolic blood pressure differently?
+
Stress typically causes a temporary increase in both systolic and diastolic pressure, but the systolic pressure often rises more significantly during acute stress.
