What is high blood pressure?

High blood pressure puts a strain on all the blood vessels in your body. This makes a blockage more likely to develop or a blood vessel in the brain weaken and bleed, both could cause a stroke.

High blood pressure usually has no symptoms but it is the biggest risk factor for stroke. The only way to know if you have high blood pressure is to have your blood pressure tested regularly.

Both lifestyle changes and medication can help to lower your blood pressure and reduce your risk of stroke.

What to do if your blood pressure is high?

If you attend a KYBP event and are advised to see your GP either as a routine appointment or as an urgent appointment, it is important that you do.

Your GP will be able to discuss your blood pressure reading in more detail, taking into account your general health and any conditions you may have.

Most people with hypertension (high blood pressure) will need to take medication to reduce it. But making changes to your lifestyle will also help to bring it down. The medication you take will be tailored to your individual needs. Most people need to take more than one medication to control their blood pressure, and you may need to try several different types before you find the ones that suit you best.
