The NHS has urged people to check their blood pressure, as an estimated 4.1 million people in England are living with high blood pressure without realising it. High blood pressure, or hypertension, occurs when the force of blood against artery walls is consistently too high, placing strain on the heart and blood vessels.
Often called a 'silent killer' because it typically has no symptoms, high blood pressure significantly increases the risk of heart attacks and strokes. In 2025, the NHS webpage on high blood pressure became the second most viewed health condition on NHS.UK, with over two million visits – up 36% from the previous year.
Dr Claire Fuller, national medical director for NHS England, said: 'Millions of people are living with high blood pressure without knowing it, but this silent killer can significantly increase the risk of heart attack and stroke if left untreated.' She added that getting a blood pressure check could 'save your life'.
Regina Giblin, senior cardiac nurse at the British Heart Foundation, said: 'Around a third of adults in the UK have high blood pressure, often without realising it. Checking your blood pressure is quick and easy and it could be one of the most important things you do for your heart health.'
People aged 40 to 74 in England are invited for an NHS Health Check every five years, which includes a blood pressure measurement. Free checks are also available at local pharmacies for those aged 40 and over, or at GP surgeries regardless of age. Home blood pressure monitors can also be used.
