High blood pressure, or hypertension, rarely has noticeable symptoms. But if untreated, it increases the risk of serious problems such as heart attacks and strokes. Around 1 in 4 adults in the UK have high blood pressure, although many will not realise it.

On May 17th, we celebrate World Hypertension Day, a day dedicated to highlighting the importance of monitoring blood pressure and bringing global awareness to the 1 billion people living with high blood pressure worldwide. High blood pressure, also known as hypertension, is defined as a systolic blood pressure consistently above 140 mm Hg and/or diastolic blood pressure consistently above 90 mm Hg. Hypertension is the #1 risk factor for heart disease, stroke, renal complications, and premature death. Usually, high blood pressure alone does not cause any symptoms. Fortunately, hypertension can be prevented and managed, by checking your blood pressure regularly, and through treatment.

Hypertension affects around 1 in 4 adults in the UK, although many will not realise it as it rarely has noticeable symptoms.

All adults over 40 are advised to have their blood pressure checked at least every 5 years.

The only way to find out if your blood pressure is high is to have your blood pressure checked.

You can check your blood pressure if you have a monitor at home, or as part of your NHS health check, at some workplaces, at a pharmacy or your GP practice.

The NHS online blood pressure tool will help you understand what your numbers mean and give you tips on how to manage your blood pressure. For more information visit nhs.uk/bloodpressure
