High Blood Pressure

What is high blood pressure?

High blood pressure (or hypertension) is when your blood pressure is consistently higher than it should be.
While not being a disease in itself, high blood pressure can lead to increased risk of heart disease and strokes.
Over time, high blood pressure slowly damages blood vessels by making them more narrow and rigid. When this happens, your heart has to work harder to push blood through your blood vessels, leading to a rise in blood pressure. It can also mean that clots are more likely to get caught and for fatty debris (atheroma) to block your blood vessels.

What are the symptoms of high blood pressure?

High blood pressure is often very difficult to detect but some of the symptoms you may notice and should alert to your doctor are:

  • Blurred vision
  • Nosebleeds
  • Shortness of breath
  • Chest pain
  • Dizziness
  • Headaches

If you have a pre-existing heart condition, it’s vital that your blood pressure or any changes in your symptoms are reported to your doctor.

Sandra’s blood pressure was sky high

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.”

How is blood pressure tested?

Blood pressure is measured in millimetres of mercury (mmHg) and is recorded as two readings:

  • Systolic pressure (higher reading): records the pressure within the blood vessels as the heart contracts
  • Diastolic pressure (lower reading): records the pressure when the heart fills up again

These readings are recorded for example as 120 / 70mmHg.
Most doctors agree that a “normal” level of blood pressure is around 120/70mmHg but up to 140/90mmHg is still low enough to have a lower risk of heart disease and stroke.

How is high blood pressure treated?

High blood pressure is often treated through a combination of drug treatments and lifestyle changes. The medication you’re provided with will depend on your age and overall health but no matter what you’re prescribed, the goal is to reduce your blood pressure to as close to the target range as possible.
Making lifestyle changes can significantly improve your blood pressure. In particular stopping smoking, maintaining a healthy weight, staying active, drinking alcohol in moderation and reducing salt intake can all make a difference.

Making lifestyle changes to improve high blood pressure

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 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 health. 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’ll become over time.
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. Likewise, with alcohol, drink in moderation and stay hydrated while you’re drinking.
