Is Your Number Up? 

1 in 2 heart attacks & strokes are linked to high blood pressure.

Check your blood pressure to know your numbers.

We are running our blood pressure campaign to raise awareness of untreated high blood pressure, which is often known as The Silent Killer. 

High blood pressure often has no visible signs or symptoms. It is therefore important to get your blood pressure checked, get treatment if necessary, and change your lifestyle if your blood pressure numbers are high.

Keep reading to find out more about high blood pressure and how you can get yours checked to find out if your number's up.

What is High Blood Pressure?

Bp guide

If your blood pressure is consistently higher than 140/90mmHg then you may have high blood pressure.

High blood pressure is not a disease in itself. However, it can lead to an increased risk of heart disease and strokes.

High blood pressure puts pressure on your heart, making it work harder. Over the years untreated high blood pressure slowly damages the blood vessels by making them narrower and more rigid. It can also cause small tears and damage to the insides of the blood vessels.

As your blood vessels become more damaged and rigid, your heart has to work even harder to push the blood through your blood vessels and the overall blood pressure rises further. It becomes easier for clots to get caught and for fatty debris (atheroma) to block your blood vessels.

This can result in clots that may travel to the heart or brain and cause a heart attack or stroke. Failure to detect and treat high blood pressure can lead to heart attack, heart failure or stroke and other conditions like dementia.

6 out of 10 strokes could be prevented by managing high blood pressure and leading a healthy lifestyle.

Keeping an eye on your Blood Pressure

High blood pressure rarely has any symptoms. The only way to know your blood pressure (BP) is to have it measured.

High blood pressure is more common as you get older so it is important to get it checked regularly. It is recommended that you have your blood pressure checked at least every 5 years, however, if you are at greater risk due to factors such as a family history with high blood pressure, you may wish to get it checked more regularly. Even if you are on high blood pressure medication, you should still have your blood pressure checked once a year. Your blood pressure could still be high and you may not know it. If this is the case, you will need to speak to your GP to make adjustments to your lifestyle or medication to treat it further.

People with type 2 diabetes should have their blood pressure checked annually.

There are a number of ways you can get your blood pressure checked:

  • Make an appointment with your GP
  • Visit your local pharmacy which may operate a blood pressure monitoring service
  • Buy a blood pressure machine for home monitoring
  • Book a Well Check with NICHS - to find more information about our health checks, click here.
  • Come along to one of our FREE Pop-Up Blood Pressure Checks taking place at MACE stores and other locations across NI during our campaign - see the full list of dates and locations below.

If your blood pressure is checked at your pharmacy, during an NICHS Well Check or with an at home blood pressure monitor and is consistently showing over 140/90mmHg, we recommend you make an appointment with your GP for further tests. If you experience any stroke or heart attack symptoms, always treat this as an emergency and call 999.

Checking your Blood Pressure at Home

Buying a blood pressure monitor to use at home can allow you to check your blood pressure easily and regularly. Watch our step-by-step video guide below and download our FAQ Guide to find out more.

Top Tips for a Healthy Blood Pressure

Maintaining a healthy blood pressure will help reduce your risk of heart and circulatory disease.

There are several changes you can make to your lifestyle to reduce high blood pressure and to maintain a healthy blood pressure:

  1. Reduce Salt Intake - Adults should eat no more than 6g of salt a day (approx. a teaspoonful). Read the labels on food packaging, choose foods lower in salt and try replacing salt with pepper, herbs and spices to add flavour.
  2. Be More Active - Move more and sit less! Adults should aim for at least 150 minutes of moderate intensity or 75 minutes of vigorous intensity physical activity each week. 2 days of strengthening exercises should also be included.
  3. Maintain a Healthy Weight - Being overweight means your heart must work harder to do everyday tasks- this leads to high blood pressure. Maintaining a healthy weight involves a combination of eating a healthy diet and being more physically active.
  4. Limit Alcohol Intake - Drinking too much alcohol increases the risk of high blood pressure and can cause weight gain. We should drink no more than 14 units of alcohol per week, with several alcohol-free days. Men should have no more than 8 units and women no more than 6 units of alcohol per session.
  5. Increase Fruit and Vegetable Consumption - Fruit and vegetables contain vitamins and minerals, along with fibre which help to reduce the risk of high blood pressure and improve our heart health. We should aim for 5 portions a day which can be fresh, frozen, canned, dried or juiced.

6 out of 10 strokes could be prevented by managing high blood pressure and leading a healthy lifestyle.

If you have been diagnosed with high blood pressure, you should also take medication for high blood pressure as prescribed by your doctor or health professional in addition to making changes to your lifestyle, unless your health professional is happy for you to stop your medication. If you are on blood pressure medication, you should go for an annual blood pressure check to review your medication.

Blood Pressure - What We Want Stormont To Do

As part of our blood pressure campaign we are calling on Stormont to do 4 things to help people to prevent or delay the onset of a heart attack or stroke.

1. Commission blood pressure and atrial fibrillation awareness campaigns
Many people are unaware that 1 in 2 heart attacks and strokes are linked to high blood pressure. They are also unaware that atrial fibrillation greatly increases your risk of stroke. We believe that the Public Health Agency should be doing more to alert the public to the risks posed by these conditions if left unchecked and untreated

2. Commission health checks in the community – especially in socially deprived areas
Opportunistic testing in the community raises awareness of the issues in an area and helps to detect patients who might not otherwise be detected. Health inequalities are a major problem in Northern Ireland with people in socially deprived areas not only living shorter lives but also living less of their lives without health problems. People should also be encouraged and facilitated to monitor their blood pressure at home.

3. Introduce ‘NHS Health Checks’ in Northern Ireland
In England an NHS Health Check is available for people who are aged 40 to 74 who do not have any pre-existing conditions. The NHS Health Check is designed to spot early signs of stroke, kidney disease, heart disease, type 2 diabetes or dementia. As we get older, we have a higher risk of developing one of these conditions. An NHS Health Check helps find ways to lower this risk. These checks are carried out every five years. We believe that these health checks should be made available in Northern Ireland too.

4. Carry out a primary care audit
An audit should be carried out of current practice around the diagnosis and management of six high risk conditions that cause stroke, heart attack and dementia: atrial fibrillation (AF), high blood pressure, high cholesterol, diabetes, non-diabetic hyperglycaemia and chronic kidney disease. This is being done in England by automatically extracting routinely held GP data under the banner of CVD Prevent. The CVDPREVENT audit aims to support quality improvement in the prevention of cardiovascular disease.

Find out more about Blood Pressure

  • When your blood pressure is taken, two measurements are recorded during a single heartbeat. When your blood pressure is written down you will see a top number and a bottom number.

    • Systolic Pressure is the top number. This is the pressure when your heart pumps blood through arteries and around your body.
    • Diastolic pressure is the bottom number. This is the pressure when your heart is resting in between beats.

    Blood pressure is measured in millimetres of mercury or mmHg. When a person has high blood pressure, the numbers on their readings begin to rise above the levels of 140/90mmHg. Ideal blood pressure is between 90/60mmHg and 120/80mmHg.

    If your blood pressure is consistently higher than 140/90mmHg then you may have high blood pressure, which is medically known as hypertension.

    One reading alone cannot diagnose high blood pressure. It must be recorded over a period of time. Generally, the lower your blood pressure, the healthier you are. But extremely low blood pressure can also be dangerous.

    People with a reading of around 90/60mmHg or lower are generally considered to have low blood pressure. For some, there may be an underlying cause that could need treatment.

  • High blood pressure is often related to unhealthy lifestyle habits, such as smoking, drinking too much alcohol, being overweight and not exercising enough. Making changes to your lifestyle will help to reduce your blood pressure. It is also important to take any medication prescribed by your doctor.

    High blood pressure can sometimes be inherited from our family. It can also increase with age.
