What is systolic vs diastolic blood pressure?
Andrew Campbell
Published May 20, 2026
Blood pressure readings are given in two numbers. The top number is the maximum pressure your heart exerts while beating (systolic pressure). The bottom number is the amount of pressure in your arteries between beats (diastolic pressure).
Besides, which is more important systolic or diastolic blood pressure?
We have discovered that systolic blood pressure (the top number or highest blood pressure when the heart is squeezing and pushing the blood round the body) is more important than diastolic blood pressure (the bottom number or lowest blood pressure between heart beats) because it gives the best idea of your risk of
Also, why is my diastolic pressure high? The second, or lower, number measures the pressure in the arteries between beats (diastolic pressure). Those factors include diabetes, kidney disease, obesity, smoking, hardening of the arteries (atherosclerosis), or a history of heart disease or a heart attack.
Subsequently, one may also ask, what is diastolic and systolic pressure?
Everyone would like to have healthy blood pressure. The top number refers to the amount of pressure in your arteries during the contraction of your heart muscle. This is called systolic pressure. The bottom number refers to your blood pressure when your heart muscle is between beats. This is called diastolic pressure.
What does it mean when the diastolic number is high?
If the bottom number (diastolic pressure) is consistently higher than 90 - this is known as Isolated Diastolic Hypertension. If you have hypertension, this higher pressure it puts extra strain on your heart and blood vessels. Over time, this extra strain increases your risk of a heart attack or stroke.

What should I do if my blood pressure is 160 over 100?
Your doctor If your blood pressure is higher than 160/100 mmHg, then three visits are enough. If your blood pressure is higher than 140/90 mmHg, then five visits are needed before a diagnosis can be made. If either your systolic or diastolic blood pressure stays high, then the diagnosis of hypertension can be made.Why diastolic blood pressure is high but Systolic is normal?
Isolated systolic hypertension is when your systolic blood pressure is high, but your diastolic blood pressure is normal. It can occur naturally with age or can be caused by a variety of health conditions including anemia and diabetes. ISH should still be treated even though your diastolic pressure is normal.What is considered a dangerous diastolic blood pressure?
A normal diastolic blood pressure is lower than 80. But even if your diastolic number is lower than 80, you can have elevated blood pressure if the systolic reading is 120-129. 80-89 is stage 1 hypertension. 90 or more is stage 2 hypertension. 120 or more is a hypertensive crisis.Is 150 90 A good blood pressure?
If you are 80 years and older, it should be less than 150/90 (“150 over 90”). In general, the lower your blood pressure, the better. A blood pressure reading of less than 90/60 is normal as long as you feel okay.What is a good blood pressure by age?
What Should Blood Pressure be According to Age?| Approx. Ideal BP According to Age Chart | ||

What does it mean when systolic is high and diastolic is low?
Isolated systolic hypertension is when your systolic blood pressure is high, but your diastolic blood pressure is normal. It can occur naturally with age or can be caused by a variety of health conditions including anemia and diabetes. ISH should still be treated even though your diastolic pressure is normal.What is the average blood pressure for a 70 year old?
Normal blood pressure is a reading below 120/80. The top number, 120, is systolic pressure, when the heart beats and is pumping blood. The bottom number, 80, is diastolic pressure, when the heart is at rest between beats.Why is my systolic high?
Isolated systolic hypertension is when your systolic blood pressure is high, but your diastolic blood pressure is normal. It can occur naturally with age or can be caused by a variety of health conditions including anemia and diabetes. ISH should still be treated even though your diastolic pressure is normal.What causes a pulse in an artery?
Pulse, rhythmic dilation of an artery generated by the opening and closing of the aortic valve in the heart. A pulse can be felt by applying firm fingertip pressure to the skin at sites where the arteries travel near the skin's surface; it is more evident when surrounding muscles are relaxed.What causes low diastolic pressure?
Two circumstances typically can result in extremely low diastolic blood pressure. The condition may be associated with severe hypotension, or it could be caused by profoundly stiff arteries that occur due to aging, diabetes or fatty buildup in the arteries (atherosclerosis).What is normal systolic blood pressure?
For a normal reading, your blood pressure needs to show a top number (systolic pressure) that's between 90 and less than 120 and a bottom number (diastolic pressure) that's between 60 and less than 80. A normal reading would be any blood pressure below 120/80 mm Hg and above 90/60 mm Hg in an adult.What is a dangerous diastolic reading?
A normal diastolic blood pressure is lower than 80. But even if your diastolic number is lower than 80, you can have elevated blood pressure if the systolic reading is 120-129. 80-89 is stage 1 hypertension. 90 or more is stage 2 hypertension. 120 or more is a hypertensive crisis.What is the fastest way to lower diastolic blood pressure?

Is a diastolic pressure of 100 dangerous?
Hypertension is diagnosed when your systolic pressure is 140 mm Hg or above or when your diastolic pressure is 90 or above. The next stage of hypertension, stage 2 hypertension, is diagnosed when your systolic pressure is 160 mm Hg or higher or your diastolic pressure is 100 mm Hg or higher.What factors affect your diastolic pressure?
The factors discussed are heart rate, arterial pressure, coronary perfusion pressure, the pericardium, and the mechanical interplay between ventricles.Can anxiety raise diastolic blood pressure?
If your back is not supported, your diastolic blood pressure measurement may be increased by 6 mmHg. These differences can increase/decrease your systolic blood pressure 2mmHg for every inch above/below your heart level. Emotional State5,6- Stress or anxiety can cause large increases in blood pressure.Can high diastolic pressure cause pain?
Among pain-free normotensives, elevated resting systolic (SBP) and diastolic (DBP) blood pressure were associated with significantly higher ISC pain thresholds (P values <0.05). Higher DBP was associated with greater clinical pain intensity among the LBP subjects (P<0.001).What does it mean if the bottom number of your blood pressure is over 100?
If the bottom number (diastolic pressure) is consistently higher than 90 - this is known as Isolated Diastolic Hypertension. If you have hypertension, this higher pressure it puts extra strain on your heart and blood vessels. Over time, this extra strain increases your risk of a heart attack or stroke.Why high diastolic blood pressure is dangerous?
People with higher systolic blood pressure had a greater risk of bleeding strokes and stable angina (chest pain), while those with higher diastolic blood pressure were more likely to be diagnosed with an abdominal aortic aneurysm. If it bursts, it can cause serious bleeding and even death.What does diastolic blood pressure tell you?
The diastolic reading, or the bottom number, 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. A normal diastolic blood pressure is lower than 80. A reading of 90 or higher means you have high blood pressure.Why is diastolic pressure important?
We have discovered that systolic blood pressure (the top number or highest blood pressure when the heart is squeezing and pushing the blood round the body) is more important than diastolic blood pressure (the bottom number or lowest blood pressure between heart beats) because it gives the best idea of your risk ofWhat factors affect diastolic blood pressure?
The factors discussed are heart rate, arterial pressure, coronary perfusion pressure, the pericardium, and the mechanical interplay between ventricles. The influence of heart rate, arterial pressure, and coronary perfusion pressure can be considered as minor provided they remain within their normal physiological range.What foods cause high blood pressure?
