Helping to fight Europe’s biggest killer

High blood pressure, or hypertension, is the leading preventable risk factor for cardiovascular disease and mortality worldwide.⁴ In England it is estimated that for every 10 people diagnosed with hypertension another 7 remain undiagnosed and untreated.⁵

By making it easy for everyone to check and track their blood pressure, Lifelight can provide early detection of hypertension and help fight Europe’s biggest killer.
