High blood pressure has no symptoms, but can lead to serious health problems such as heart attack or stroke if it’s ignored.
Everyone over 40 should know their blood pressure.
If it’s been more than five years since your last check, contact your GP, visit a community pharmacy that offers the service, or take your reading at home if you have a blood pressure monitor.
