High blood pressure (hypertension) rarely has symptoms.
Around 30% of people in England have high blood pressure but many don’t know it. If left untreated, high blood pressure increases your risk of a heart attack or stroke.
The only way of knowing there is a problem is to have your blood pressure measured.
All adults should have their blood pressure checked at least every five years.
