blood pressure treatment options overview

Overview

Blood pressure is the force of blood pushing against the walls of your blood vessels. High blood pressure (hypertension) means this force is too high, which can damage your heart and blood vessels over time. Treatment options help lower that force to a safe level, reducing your risk of serious health problems.

Yes, high blood pressure is very common. About 1 in 3 adults worldwide have it, and many don't know they have it.

Anyone can develop high blood pressure, but it becomes more common as you get older. It can also run in families and is linked to lifestyle factors like diet, exercise, and stress.

Symptoms

Common symptoms

• Most people with high blood pressure have no symptoms at all, which is why it's often called a 'silent' condition.

Symptoms in children

• In children, high blood pressure rarely causes symptoms. It may be found during a routine check-up. If symptoms occur, they can include headaches or blurred vision.

Symptoms in older adults

• Older adults with high blood pressure might not feel different, but they may be at higher risk for complications like stroke or heart disease. Some people may notice dizziness or fatigue.

Causes

Main causes

• For most people, the exact cause isn't known (primary hypertension). It develops over time due to a combination of factors.
• In some cases, high blood pressure is caused by an underlying condition like kidney disease or a hormone problem (secondary hypertension).

Risk factors

• Being overweight or obese
• Eating too much salt
• Not getting enough physical activity
• Drinking too much alcohol
• Smoking or using tobacco
• Getting older
• Having a family history of high blood pressure
• Having chronic stress

When to see a doctor

See a doctor urgently if:

• If you have a blood pressure reading of 180/120 mmHg or higher with chest pain, shortness of breath, or severe headache, call for emergency help right away.
• If your reading is 180/120 mmHg or higher but you feel fine, see your doctor or go to an urgent care clinic the same day.

Book a routine appointment if:

• Adults should have their blood pressure checked at least every 2 years if it is normal, and more often if it is high or if you have other risk factors.
• If you already have high blood pressure, you'll need regular check-ups to monitor it.

Diagnosis

A healthcare professional measures your blood pressure with a cuff around your arm. A diagnosis of high blood pressure is usually made after two or more readings on separate visits are consistently high.

Tests that may be done

• Blood pressure measurement (sphygmomanometer)
• Ambulatory blood pressure monitoring (wearing a device for 24 hours)
• Home blood pressure monitoring (you check it yourself)
• Blood tests to check for kidney function, blood sugar, and cholesterol
• Urine test
• Electrocardiogram (ECG) to check heart function

What to expect at your appointment

Your doctor will explain your numbers and what they mean. They may ask about your lifestyle, family history, and any symptoms. You'll likely be asked to check your blood pressure at home as well. The goal is to get a clear picture of your overall health and then work together on a plan that's right for you.

Treatment

Treatment for high blood pressure focuses on lowering your numbers to a safe level. This often includes a combination of lifestyle changes and medication. The goal is to reduce your risk of heart attack, stroke, and other complications. Treatment is a long-term partnership with your healthcare team.

Self-care at home

• Limit salt: aim for less than 5-6 grams (about 1 teaspoon) of salt per day.
• Eat a balanced diet rich in fruits, vegetables, whole grains, and low-fat dairy (like the DASH diet).
• Get regular physical activity – aim for at least 30 minutes most days.
• Maintain a healthy weight or lose weight if needed.
• Limit alcohol to no more than 1-2 drinks per day (for men) and 1 drink per day (for women).
• Quit smoking if you smoke.
• Manage stress with relaxation techniques, hobbies, or talking to someone you trust.

Medical treatments

If lifestyle changes aren't enough, your doctor may prescribe medication. There are several types of blood pressure medications that work in different ways – for example, by helping your blood vessels relax, reducing the amount of fluid in your body, or slowing your heartbeat. Most people need more than one type. Your doctor will choose what's best for you based on your health and other conditions. It's important to take your medication exactly as prescribed and not stop without talking to your doctor.

When is surgery considered?

Surgery is rarely needed for high blood pressure itself. In some cases, if high blood pressure is caused by a narrowed artery (like in the kidney) or a tumor (like in the adrenal gland), surgery to fix that problem may help. But for most people, treatment involves lifestyle changes and medication.

Living with this condition

Living with high blood pressure means making healthy choices a part of your daily routine. It's a condition you can manage well with the right habits and support. You'll need to check your blood pressure regularly, take any medications as prescribed, and keep up with doctor's appointments.

Lifestyle tips

• Eat heart-healthy meals with plenty of fruits and vegetables.
• Cut back on processed foods and added salt.
• Make physical activity a habit – walking, swimming, cycling are great options.
• Limit alcohol and avoid tobacco.
• Find healthy ways to cope with stress, like deep breathing or yoga.

Diet and exercise

A diet low in salt and rich in potassium (from fruits and vegetables) can help lower blood pressure. Aim for at least 150 minutes of moderate-intensity exercise each week, such as brisk walking. Even small increases in activity make a difference.

Mental health and emotional wellbeing

Being diagnosed with a chronic condition can feel overwhelming. You might feel anxious or frustrated. It's normal. Talk to your healthcare provider about these feelings. Managing stress is also a key part of treatment, so don't ignore your mental health.

Prevention

You can lower your risk of developing high blood pressure by eating a healthy diet, staying active, maintaining a healthy weight, limiting alcohol, not smoking, and managing stress. These same steps also help if you already have high blood pressure.

Screening programmes

Regular blood pressure checks are the best way to catch high blood pressure early. Adults should have their blood pressure measured at every healthcare visit or at least every 2 years. You can also check it at home with a reliable monitor.

Complications

If left untreated

• Heart attack or heart failure
• Stroke
• Kidney damage or failure
• Vision loss
• Aneurysm (a bulging blood vessel that can burst)

Long-term outlook

The outlook for high blood pressure is very good when it's managed properly. With lifestyle changes and medication if needed, most people can keep their blood pressure within a healthy range and reduce their risk of complications. It's a condition you can live a long, full life with – just stay on top of your numbers and your health.
