High blood pressure usually has no obvious symptoms and many people have it without knowing.
Untreated high blood pressure can lead to serious diseases, including stroke and heart disease. The only way to know if you have high blood pressure (medically known as hypertension) is to have your blood pressure measured. All adults should get their blood pressure checked at least once every five years.
In some rare cases, where a person has very high blood pressure, they can experience symptoms including:
- a persistent headache
- blurred or double vision
- nosebleeds
- shortness of breath
Visit your GP as soon as possible if you have any of these symptoms.
