what do blood pressure numbers mean uk?
236984
Systolic blood pressure between 90 and 119, and diastolic pressure between 60 and 79 is the ideal blood pressure (a range expressed in shorthand as 90/60 to 119/79). Anything above 140/90 is considered to be high blood pressure.
62446
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. This is called diastolic pressure.

A normal reading would be any blood pressure below 120/80 mm Hg and above 90/60 mm Hg in an adult. If you're in the normal range, no medical intervention is needed.
205452
Blood pressure of less than 120 over 80 is considered a normal reading for people 18 and over. A borderline systolic pressure of 120 to 139 or a diastolic pressure of 80 to 89 needs to be closely monitored. This is called prehypertension.
39527
A normal blood pressure for an adult is defined as 90 to 119 systolic over 60 to 79 diastolic. The range between 120 to 139 systolic and 80 to 89 diastolic is called pre-hypertension, and readings above that indicate hypertension, or high blood pressure.
760584
The bottom number is the diastolic blood pressure, which is the force as your heart relaxes. These are the standard classifications for normal and high blood pressure. Normal blood pressure: 90/60 to under 120/80 mm Hg. Prehypertension, or risk for hypertension: 120-139/80-89 mm Hg.

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.
834749
High blood pressure (hypertension) is when one or both of your blood pressure readings are higher than 130/80 mm Hg most of the time. If the top blood pressure number is between 120 and 130 mm Hg, and the bottom blood pressure number is less than 80 mm Hg, it is called elevated blood pressure.
31689
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).
956718
Those with a blood pressure reading anywhere from 120/80 up to 129/80 are classified within a category called elevated blood pressure. Hypertension is defined as a reading of 130/80 or higher.
6858
The bottom number refers to your blood pressure when your heart muscle is between beats. This is called diastolic pressure. Both numbers are important in determining the state of your heart health. Numbers greater than the ideal range indicate that your heart is working too hard to pump blood to the rest of your body.

For example, if your blood pressure is "140 over 90" or 140/90mmHg, it means you have a systolic pressure of 140mmHg and a diastolic pressure of 90mmHg. As a general guide: ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg.
262576
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. Although these numbers aren't technically considered high blood pressure, you've moved out of the normal range.
144551
Current guidelines define a normal blood pressure reading as less than 120 mm Hg systolic (the top number) over 80 mm Hg diastolic (the bottom number). Doctors typically determine you have low blood pressure if your reading is below 90/60 mm Hg.
775586
So if your top number is over 140 or the bottom number is over 90, you may be diagnosed with high blood pressure, regardless of the other number. If your top number is under 90 or your bottom number is under 60, you may be diagnosed with low blood pressure.
721173
The bottom number tells you what your blood pressure is when your heart is at rest between heartbeats. It is called diastolic pressure.
537510
You probably have high blood pressure (hypertension) if your blood pressure readings are consistently 140 over 90, or higher, over a number of weeks. You may also have high blood pressure if just one of the numbers is higher than it should be over a number of weeks.
