High blood pressure is linked to more than half of all strokes worldwide, yet it often shows no obvious symptoms, meaning millions could be at serious risk without knowing it, a cardiologist warns.
The NHS estimates that approximately 4.1 million people in England are currently living with high blood pressure without knowing it, widely regarded as the 'silent killer' behind strokes and heart attacks. The condition typically presents no obvious symptoms, meaning that in most cases people may feel perfectly well while actually facing a considerably greater risk of a serious health emergency.
The Hidden Danger of Elevated Readings
When elevated pressure persists over an extended period, it can result in damaged blood vessels, leading to narrowing, blockages and even rupture, according to the World Stroke Organisation. Dr Francesco Lo Monaco, consultant cardiologist and founder of the National Longevity Clinic, noted that an absence of symptoms can frequently represent one of the greatest dangers, which is precisely why routine blood pressure monitoring is so important.
Blood pressure measures the force of blood pushing against arterial walls, and if excessively high, it may place additional strain on the vessels supplying your heart and other vital organs. Dr Lo Monaco stated: "High blood pressure is one of the most important risk factors we can identify and treat to reduce the risk of stroke. The difficulty is that many people assume they are healthy because they feel well."
How to Check and Manage Your Risk
The most effective approach to minimising risks involves having blood pressure monitored, bearing in mind that a measurement of 140/90 mmHg or higher in a medical environment, or 135/85 mmHg or higher when taken at home, is typically regarded as elevated. A single reading doesn't necessarily confirm a diagnosis, meaning repeated assessments or home monitoring may sometimes prove more appropriate.
In addition, it's recommended to maintain a well-balanced diet with restricted salt content and engage in regular physical activity, while steering clear of smoking and maintaining alcohol consumption within suggested guidelines. Dr Lo Monaco added: "The most effective approach is not to focus on one magic food or supplement. It is about understanding your individual risk, checking your blood pressure and cholesterol, and addressing problems early."
He concluded: "If you discover that your blood pressure is high, do not panic - but do not ignore it either. Speak to a healthcare professional about what your results mean and whether lifestyle changes, medication or both are appropriate."
