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.

Right now, 5 million UK adults aged 18-64 may have undiagnosed high blood pressure – increasing their risk of heart attack, stroke, and kidney disease. Many don’t even know it. That’s why getting a simple blood pressure check at home could literally be a lifesaver.

High blood pressure is known as the “silent killer” – no symptoms, just risk. But knowing your numbers gives you the power to act – whether that’s eating less salt, being more active, or starting medication if needed. Age doesn’t matter. Everyone should Know Their Numbers!
