A comprehensive guide to understanding and managing your blood pressure using our Blood Pressure Calculator tool.
A blood pressure test is a simple way of checking if your blood pressure is too high or too low. Blood pressure is the term used to describe the strength with which your blood pushes on the sides of your arteries as it's pumped around your body.
Blood pressure is measured in millimetres of mercury (mmHg) and is given as two figures:
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.
High blood pressure (hypertension) can increase your risk of developing serious problems, such as heart attacks and strokes, if it's not treated. Low blood pressure (hypotension) is not usually a problem, although it can cause dizziness and fainting in some people.
Having this quick test is the only way to find out what your blood pressure is – and it could save your life.
Blood pressure machines vary, but they're all a type of measuring device, which often have an arm cuff attached to it. The cuff is usually wrapped around your upper arm and filled with air until it feels tight. This can feel uncomfortable but it only lasts a few seconds.
It's important to relax and not talk during this time, because this is when your blood pressure is measured. An automatic device usually picks up the measurements from sensors in the arm cuff, which are sent to a digital display. You should get the results straight away.
Your blood pressure reading can tell you how healthy your blood pressure is.
A blood pressure reading between 120/80mmHg and 140/90mmHg could mean you're at risk of developing high blood pressure if you don't take steps to keep your blood pressure under control.
If your blood pressure is found to be too high or too low, your GP or the healthcare professional performing the test can advise you about ways to control it.
In some cases, you may be referred to a doctor such as a cardiologist (heart specialist) to discuss treatment options.
