Heart health plays an important role in overall wellbeing. One of the key ways to understand how healthy your heart and blood vessels are is by monitoring your blood pressure.
What is blood pressure?
Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps. It is recorded as two numbers:
Systolic pressure – the pressure when the heart beats
Diastolic pressure – the pressure when the heart rests between beats
Blood pressure is measured in millimetres of mercury (mmHg) and written as, for example, 120/80 mmHg.
Why is monitoring blood pressure important?
High blood pressure (also known as hypertension) often has no obvious symptoms. Many people may feel well even when their blood pressure is raised. Over time, untreated high blood pressure increases the risk of:
Heart attack
Stroke
Kidney disease
Problems with vision
Regular monitoring can help to identify raised readings early, allowing people to seek medical advice where needed.
Who should have their blood pressure checked?
Blood pressure checks are recommended for:
Adults aged over 40
People with a family history of heart disease
People who smoke
Those who are overweight
People with diabetes
Anyone who has previously been told their blood pressure is high
Your pharmacist or GP can advise how often your blood pressure should be checked based on your individual circumstances.
How is blood pressure measured?
Blood pressure can be measured:
Using an automated monitor in a pharmacy or GP practice
At home using a validated home monitor
To get an accurate reading:
Sit quietly for five minutes before measuring
Keep your arm supported at heart level
Avoid caffeine, smoking and exercise for at least 30 minutes beforehand
It is important not to rely on a single reading. Healthcare professionals usually look at several readings over time.
Looking after your heart
Lifestyle measures that may support heart health include:
Eating a balanced diet with plenty of fruit and vegetables
Reducing salt intake
Being physically active
Maintaining a healthy weight
Avoiding smoking
Drinking alcohol within recommended limits
If your blood pressure is raised, your GP may recommend lifestyle changes and, in some cases, medication.
When to seek medical advice
You should speak to your GP or pharmacist if:
You have consistently high readings
You feel unwell or have concerns about your blood pressure
You have been prescribed blood pressure medication and have questions
Blood pressure monitoring is a simple step that can provide valuable information about your heart health.
