High blood pressure (also called hypertension) is when your blood pressure is consistently higher than it should be.
High blood pressure is not a disease, but it can lead to increased risk of heart disease and strokes.
Over time, high blood pressure slowly damages blood vessels, making them more narrow and rigid. When this happens, your heart has to work harder to push blood through your blood vessels. Narrow, rigid blood vessels are also more likely to be blocked by a clot or a fatty build-up (atheroma).
High blood pressure is often very difficult to detect, and you may not have any symptoms. However, you should alert your doctor if you notice:
If you have a pre-existing heart condition, it is vital that changes in your blood pressure or any of your symptoms are reported to your doctor.
Sandra from Dunfermline had a stroke just as lockdown was beginning in March 2020. Because of the pandemic, the usual support wasn’t there.
“I had to visit my GP because my blood pressure was sky high and that was one of the reasons I had a stroke in the first place,” she explains.
“I was told to wait a week to see if my blood pressure changed and I felt that my situation wasn’t taken very seriously, given I had very recently had a stroke. I left the surgery feeling rather worried and stressed.”
But Chest Heart & Stroke Scotland’s amazing support worker Rhona was there to make sure Sandra got the important medical help she needed.
“Rhona instantly sprang into action and called the doctor for me and suggested they rethink my blood pressure medication. I’ve now been put on new medication and my blood pressure readings have gone down.
“Without Rhona, my stress levels would’ve been shocking. I would’ve been feeling depressed and I wouldn’t be able to cope.”

Blood pressure is measured in millimetres of mercury (mmHg) and includes two readings:
These readings are recorded as a fraction, with the systolic pressure over the diastolic pressure – for example, 120 / 70mmHg.
Most doctors agree that a “normal” level of blood pressure is around 120/70mmHg, but the risk of heart attack and stroke only seems to go up significantly above 140/90mmHg.
High blood pressure is usually treated through a combination of drug treatments and lifestyle changes. Which medication is best for you will depend on your age and overall health, but no matter what you’re prescribed, the goal is to bring your blood pressure as close to the target range as possible.
Making lifestyle changes can also improve your blood pressure. In particular: stopping smoking, maintaining a healthy weight, staying active, keeping your alcohol intake low, and reducing salt intake can all make a difference.
Managing your high blood pressure can feel like a huge challenge, but small changes to your lifestyle and habits over time lead to big improvements.
If you’re a smoker, one of the best things that you can do for your heart health is to stop smoking. There are many ways to help quit smoking available to you and your loved ones.
Getting in the habit of exercising daily can improve your heart health, as well as being great for mental and physical health in general. Whether this is a daily walk, yoga, or swimming, even just 30 minutes a day will be beneficial and the more you do it, the easier it will become over time. Even if you struggle to do these activities, there are often more accessible forms of exercise available.
Home cooked meals tend to have a lot less salt than ready meals and takeaways. If you’re prone to reaching for the takeaway menu, try to reduce this over time and get into the habit of cooking homemade meals, even if they’re simple.
Only drink alcohol in moderation and stay hydrated while you’re drinking. In general, try to drink plenty of water every day.
