what does the lower number in blood pressure represent?

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.

Normal blood pressure is 139/89 or lower. Around 110/70 is ideal. During a postural hypotension episode, the top measurement drops 20 points or more, or the bottom number drops 10 points or more.

Normal blood pressure is defined when the top number (systolic) is less than 120 mm Hg and the bottom number is under 80 mm Hg. Anything less than 90 over 60 is considered low, but low doesn't always mean unhealthy or dangerous. Sometimes there are reasons for low blood pressure.

What would you define as “too low,” and why is that a problem? A diastolic blood pressure of somewhere between 90 and 60 is good in older folks. Once you start getting below 60, that makes people feel uncomfortable. A lot of older folks with low diastolic pressures get tired or dizzy and have frequent falls.

As a general guide: normal blood pressure is considered to be between 90/60mmHg and 120/80mmHg. high blood pressure is considered to be 140/90mmHg or higher. low blood pressure is considered to be 90/60mmHg or lower.

"In a healthy person, low blood pressure is a sign of good health as long as the systolic pressure is above 80," explains Dr. Pacold. "Very low blood pressure in a person with heart disease could be a sign of heart failure."

Low blood pressure is also known as hypotension. People with a reading of around 90/60, or less, are commonly regarded as having low blood pressure. Some people who have low blood pressure experience symptoms as a result of it.

Numbers higher than 120/80 mm Hg are a red flag that you need to take on heart-healthy habits. When your systolic pressure is between 120 and 129 mm Hg and your diastolic pressure is less than 80 mm Hg, it means you have elevated blood pressure.

For example, 120/80 mm Hg. 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.

Low blood pressure is a measurement of 90/60mmHg or lower. When your blood pressure drops, your heart rate increases and the blood vessels in other parts of the body constrict (narrow) to help maintain blood pressure.

if your top number is 140 or more - then you may have high blood pressure, regardless of your bottom number. if your bottom number is 90 or more - then you may have high blood pressure, regardless your top number. if your top number is 90 or less - then you may have low blood pressure, regardless of your bottom number.

Blood pressure usually ranges between 90 to 250 for the top or maximum number (systolic) and 60 to 140 for the bottom or minimum number (diastolic). A healthy blood pressure is 120/80 or less, but the lower you can get it, the better.

The top number of your blood pressure reading tells you the force of the blood against artery walls when your heart beats. It is called systolic pressure. The bottom number tells you what your blood pressure is when your heart is at rest between heartbeats. It is called diastolic pressure.
946095
The lower reading, known as diastolic pressure, measures that force as the heart relaxes between contractions. Adult blood pressure is considered normal at 120/80.

When your doctor takes your blood pressure, it's expressed as a measurement with two numbers, with one number on top (systolic) and one on the bottom (diastolic), like a fraction. For example, 120/80 mm Hg. The top number refers to the amount of pressure in your arteries during the contraction of your heart muscle.

Normal blood pressure is usually considered 120/80 mm Hg or less. It is not treated with medicines generally until after it gets to 140/90 mm Hg or more. This is because there is no conclusive evidence that the benefits outweigh the risks of treating with medicines to blood pressure lower than 140/90 mm Hg.

Your blood pressure reading is usually given as the systolic blood pressure number over the diastolic blood pressure number, such as 138/72. Normal blood pressure for adults is defined as a systolic pressure of less than 120 and a diastolic pressure of less than 80. This is stated as 120/80.
