High blood pressure is often called the silent killer, and new figures show just how apt that description is. According to a study of 1.4 million adults, more than one-third of adults in England have high blood pressure, and two-thirds of those affected are unaware of their diagnosis. The condition is quietly raising their risk of heart attack, stroke and kidney disease while producing no symptoms to warn them.
The scale of the finding is striking. Because hypertension typically causes no obvious signs, it can progress for years undetected, damaging blood vessels and organs in the background. The study suggests that a vast number of people are living with a treatable condition that they do not know they have — a gap that represents both a major public health challenge and a major opportunity. Detecting high blood pressure is cheap and simple, and treating it is highly effective. The results underline the importance of routine checks and widespread screening, and they raise urgent questions about why so many people are falling through the net.
