Why is Know Your Numbers! needed?

6 million people in the UK have high blood pressure and don’t know.


Here are just some of the reasons why everyone should Know Their Numbers.

1 in 2 strokes and heart attacks are the result of high blood pressure.

1 in 3 adults in the UK have high blood pressure. 

1 in 2 adults with high blood pressure don’t know they have it or aren’t receiving treatment. 

6 million people in the UK alone have high blood pressure and don’t know it. 

£2.1 billion – that’s how much high blood pressure costs the NHS every year.

Because high blood pressure usually has no symptoms, the first sign of it could be a heart attack or stroke. It can cause kidney disease, dementia and other illnesses too. But these tragedies can be prevented with medications and lifestyle changes

Our Know Your Numbers! campaign reaches those who have high blood pressure and don’t know it. It gives them the chance to get the treatment and support they need to lower their blood pressure and lead a long and healthy life.
