High Blood Pressure Treat The Risk Not The Number

Overview

High blood pressure, also called hypertension, means the pressure in your arteries is higher than is healthy over time. Blood pressure is written as two numbers. The top number is the pressure when your heart beats. The bottom number is the pressure when your heart rests between beats. One high reading does not always mean you have high blood pressure. The important point is that treatment is about lowering your risk of heart attack, stroke, kidney disease and other problems — not just chasing a perfect number.

Very common. Around one in three adults worldwide has high blood pressure, and many people do not know it.

Anyone can have high blood pressure, but it is more common as people get older. It is also more likely if you have a family history, certain health conditions, or risk factors such as a diet high in salt, little physical activity, or smoking.

Symptoms

Common symptoms

• Usually no symptoms at all.
• Some people mention headaches, nosebleeds, dizziness or blurred vision, but these are not reliable signs and can have other causes.
• If blood pressure is very high, you may get a severe headache, shortness of breath, chest pain, vision changes, confusion or weakness. Seek urgent help.

Symptoms in children

• Often no symptoms. It is usually found during a routine check or when checking for another condition.
• In children, high blood pressure can be linked to kidney, heart or hormone conditions, so tests may be needed.
• Severe cases can cause headaches, vomiting, vision changes, seizures or confusion. Get emergency care.

Symptoms in older adults

• Often silent, as in younger adults.
• Dizziness, falls, confusion or vision changes can happen when blood pressure is very high or changes quickly.
• Other health conditions and medicines can affect readings. Ask for a review if readings vary a lot.

Causes

Main causes

• Most people have no single clear cause. This is called primary or essential high blood pressure.
• Sometimes another condition is the cause, such as kidney disease, sleep apnoea (breathing pauses during sleep), hormone problems, or narrowing of certain blood vessels.
• Some medicines, pregnancy, and recreational drugs can raise blood pressure.

Risk factors

• Older age
• Family history of high blood pressure
• Too much salt in the diet
• Not enough physical activity
• Overweight or obesity
• Drinking too much alcohol
• Smoking
• Diabetes
• Kidney disease
• Sleep apnoea
• Stress and poor sleep
• Some communities and ethnic groups have a higher risk

When to see a doctor

See a doctor urgently if:

• A repeated reading of 180/120 mmHg or higher, even without symptoms.
• New symptoms such as severe headache, chest pain, shortness of breath, weakness, confusion or vision changes.
• Home readings that suddenly become much higher than usual.
• Side effects from treatment that worry you.

Book a routine appointment if:

• Your reading is often above target at health checks.
• You have risk factors such as diabetes, kidney disease or a strong family history.
• You want advice on home monitoring or lifestyle changes.
• Your readings are up and down, or you have questions about your treatment plan.

Diagnosis

Your clinician will usually check your blood pressure more than once, ask about your health and medicines, and may ask you to use a home monitor or wear an ambulatory monitor for 24 hours. They look at your readings together with your overall risk, not one number alone.

Tests that may be done

• Repeat blood pressure readings in the clinic
• Home blood pressure monitoring, if suitable
• 24-hour ambulatory blood pressure monitoring
• Blood tests for kidney function, cholesterol, sugar and other checks
• Urine test
• Heart tracing (ECG)
• Sometimes specialist tests if high blood pressure starts young, is very hard to control, or another cause is suspected

What to expect at your appointment

You may need a few visits. Diagnosis is based on patterns over time. Your clinician will discuss your overall chance of heart and circulation problems, not just the reading.

Treatment

Treatment aims to lower your risk of stroke, heart attack, kidney disease and other problems. That means looking at the whole picture: your blood pressure, age, other conditions, family history and lifestyle. A reading slightly above target may not need medicine straight away, while a higher reading with other risks may need treatment sooner. Your plan should be reviewed regularly.

Self-care at home

• Check your blood pressure at home if your clinician advises, and keep a simple record.
• Cut down on salt, especially from processed foods.
• Eat more fruit, vegetables, beans, whole grains and low-fat dairy. Choose heart-healthy fats.
• Be active most days. Build up gradually.
• If you are overweight, aim for gradual weight loss.
• Limit alcohol and avoid binge drinking.
• Stop smoking and get help if needed.
• Get enough sleep and manage stress.
• Take any prescribed medicine as agreed, and do not stop without advice.

Medical treatments

If lifestyle changes are not enough, or your risk is high, your clinician may suggest blood pressure medicine. There are several types. They choose based on your age, other conditions, pregnancy plans, kidney function and side effects. You may need to try more than one, or take a combination. Take it exactly as prescribed, keep appointments, and tell your provider about side effects rather than stopping on your own. Do not take medicines, supplements or cold remedies that raise blood pressure without checking first.

When is surgery considered?

Surgery is rarely used for high blood pressure. If a specific cause is found — such as a narrowed kidney artery or a hormone-producing growth — a specialist may discuss a procedure. Most people are treated with lifestyle changes and medicine.

Living with this condition

High blood pressure is usually a long-term condition. The goal is steady care: take medicine if prescribed, check readings as advised, keep appointments, and make small lifestyle changes you can stick with. Do not chase one perfect number. Look at the trend and your overall risk.

Lifestyle tips

• Plan meals around vegetables, fruit, beans, whole grains, fish, nuts and healthy oils.
• Choose water instead of sugary drinks.
• Move more: walking, cycling, swimming or dancing.
• Stand or move regularly if you sit a lot.
• Keep alcohol within recommended limits and have alcohol-free days.
• Protect your sleep and make time to relax.
• Ask for help to stop smoking.

Diet and exercise

A heart-healthy eating pattern and regular activity can lower blood pressure and improve cholesterol and blood sugar. Aim for activity you enjoy and can keep up. If you have other health conditions or are pregnant, ask your clinician what is safe for you.

Mental health and emotional wellbeing

Worrying about numbers can make you check too often and feel anxious. Stress can raise blood pressure for a short time. Try not to test more than advised, and bring your worries to your clinician. If you feel low, anxious or overwhelmed, tell someone. If you ever have thoughts of harming yourself, contact your local crisis service or emergency services right away.

Prevention

You cannot control every risk, such as age or family history. But many people can prevent or delay high blood pressure by eating well, being active, keeping a healthy weight, limiting salt and alcohol, not smoking, and getting enough sleep.

Vaccines

There is no vaccine for high blood pressure. Stay up to date with routine vaccines recommended for your age and health. Ask your provider, especially if you have heart or kidney conditions.

Screening programmes

Blood pressure is usually checked at routine health visits. Adults should ask how often they need a check. Some people need home monitoring or earlier checks because of family history, diabetes, kidney disease or pregnancy.

Complications

If left untreated

• Heart attack and heart failure
• Stroke and vascular dementia
• Kidney disease
• Eye damage and vision loss
• Peripheral artery disease (poor circulation in the legs)
• Aortic aneurysm (a bulge in the main blood vessel)

Long-term outlook

The good news is that treating high blood pressure works. Small, steady changes and regular care can lower your risk of serious problems. Many people live full, active lives with well-managed blood pressure. Work with your healthcare team to find a plan you can keep up.
