screening for blood pressure
Informed by recognized medical guidance
Overview
Blood pressure screening is a quick, painless check that measures the force of your blood against the walls of your arteries. It helps find high blood pressure early, even when you feel fine.
Key facts
- High blood pressure often has no symptoms, so screening is the only way to know.
- A one-off high reading does not mean you have high blood pressure; it needs to be confirmed over time.
- Blood pressure screening is simple and can be done at your GP practice, pharmacy, or with a home monitor.
Yes. High blood pressure affects about one in three adults worldwide.
It can affect people of any age, but the risk increases as you get older. It can also affect children, especially those who have other health conditions or a family history.
Symptoms
- Chest pain or pressure
- Severe headache that comes on suddenly
- Blurred vision or seeing spots
- Difficulty speaking or weakness on one side of your face or body
- Shortness of breath
- A nosebleed that does not stop
- ⚠Dizziness or lightheadedness that persists
- ⚠A severe headache that is different from your usual headaches
- ⚠Swelling in your feet or ankles

Common symptoms
- Most people with high blood pressure have no symptoms at all.
- Some people may experience headaches, nosebleeds, or dizziness, but these are not specific and rarely the only sign.
Symptoms in children
- Children usually have no symptoms. High blood pressure is often found during a routine health check.
- In rare severe cases, a child may have headaches, blurred vision, or unusual tiredness.
Symptoms in older adults
- Older adults may have no symptoms, but some feel dizzy, tired, or lightheaded.
- Sometimes blood pressure changes can cause falls or fainting.
Causes
Main causes
- In most cases, the exact cause is unknown.
- Lifestyle factors such as too much salt, lack of exercise, smoking, and heavy alcohol use can raise blood pressure.
- Some medical conditions, such as kidney disease or thyroid problems, can also cause high blood pressure.
Risk factors
- Age (above 40)
- Being overweight or living with obesity
- A family history of high blood pressure
- A diet high in salt and processed foods
- Not being physically active
- Smoking
- Drinking too much alcohol
- Long-term conditions like diabetes or kidney disease
When to see a doctor
See a doctor urgently if:
- If you have a very high home reading and feel unwell, call your doctor for advice the same day.
- If you have symptoms from the urgent list above, arrange a same-day appointment.
Book a routine appointment if:
- Have your blood pressure checked at least once every two years if you are over 18.
- If you have risk factors like diabetes, a family history, or are over 40, ask for a check at least once a year.
Diagnosis
A blood pressure screening is done with a cuff placed around your upper arm. To confirm high blood pressure, your doctor will usually take two or more readings on at least two different days. Sometimes they may ask you to wear a monitor for 24 hours.
Tests that may be done
- Blood pressure check with a cuff (sphygmomanometer)
- Repeated checks at the clinic or home
- 24-hour ambulatory blood pressure monitoring
- Home blood pressure monitoring with a validated device
What to expect at your appointment
You will sit in a chair with your back supported, feet flat on the floor, and arm at heart level. The cuff will inflate, squeezing your arm, and then deflate. It takes about a minute and is not harmful. You can go back to your normal day immediately after.
Treatment
Treatment for high blood pressure focuses on lowering your numbers to protect your heart, brain, and kidneys. It combines lifestyle changes, often with medication, and regular monitoring.
Self-care at home
- Cut down on salt in your meals and avoid highly processed foods.
- Move more: aim for at least 30 minutes of moderate activity on most days.
- Maintain a healthy weight, or lose weight if you need to.
- Limit alcohol to no more than the recommended amount.
- Quit smoking and avoid second-hand smoke.
- Manage stress with breathing exercises, mindfulness, or hobbies.
Medical treatments
If lifestyle changes are not enough, medicines can help lower blood pressure. There are several types available that work in different ways, and your doctor will choose the best option for you. Treatment is usually long-term, and it is important to take medication exactly as prescribed. It may take time to find the right balance, but many people do well with one or two tablets.
When is surgery considered?
Surgery is rarely used for high blood pressure. However, if a narrowed artery (for example, a kidney artery) is causing the problem, a specialist procedure may be considered.
Living with this condition
You can live a full and active life with high blood pressure. The key is to keep your blood pressure under control with a healthy routine and any medicines your doctor prescribes. Regular check-ups help you stay on track.
Lifestyle tips
- Monitor your blood pressure at home if recommended, and keep a simple record.
- Attend your routine appointments.
- Find support from your family, friends, or community.
- Set small, realistic goals for diet and exercise.
Diet and exercise
Eat a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins. Reduce salt and sugary drinks. Exercise such as brisk walking, swimming, or cycling can lower your pressure. Aim for at least 150 minutes of moderate exercise each week, spread over several days.
Mental health and emotional wellbeing
Being told you have high blood pressure can feel worrying. Stress and anxiety can make your blood pressure higher. It is important to talk about how you feel with someone you trust, or with a counsellor. Simple relaxation techniques can help.
Prevention
You can lower your chances of developing high blood pressure by keeping a healthy weight, eating well, reducing salt, staying active, and avoiding smoking and too much alcohol. Prevention starts with small steps that become habits.
Vaccines
There is no vaccine for high blood pressure.
Screening programmes
Screening is the only way to know if you have high blood pressure. Regular checks, as often as your doctor advises, help detect it early before it causes damage.
Complications
If left untreated
- Heart attack or heart disease
- Stroke
- Heart failure
- Kidney damage or kidney failure
- Vision loss
- Memory and thinking problems over time
Long-term outlook
The outlook is often very positive. Even a small drop in blood pressure can reduce your risk of serious complications. With the right treatment plan and a healthy lifestyle, most people can keep their blood pressure well controlled and continue living a normal, active life.
