NHS Faces Challenges in Controlling Rising High Blood Pressure

Concerns about rising blood pressure in the UK have intensified as recent studies reveal a troubling trend in hypertension management. Once considered a success story for the National Health Service (NHS), the treatment of high blood pressure has stalled and, in some cases, regressed. This condition, often referred to as a “silent killer,” significantly contributes to heart attacks and strokes, yet many individuals remain undiagnosed and untreated.

Despite initial advancements in identifying and managing high blood pressure, data indicates that improvements have plateaued over the past decade. A study published in BMJ Medicine highlights how the COVID-19 pandemic further exacerbated the situation, leading to disrupted healthcare access and diminishing control over blood pressure levels. Experts warn that the current state represents a “perfect storm” of factors, including unhealthy lifestyle choices and barriers to accessing healthcare.

Impact of Lifestyle and Healthcare Access

Professor Ian Wilkinson, president of the British and Irish Hypertension Society, emphasizes the dire implications of untreated hypertension. He noted, “Hypertension will kill more people in the UK than anything else. But we’ve stalled [on treating it], and we’re going backwards.” Blood pressure is defined as the force exerted by blood against the walls of blood vessels. Elevated levels can cause severe health issues, including kidney damage, strokes, and heart attacks.

Historically, healthcare providers in the UK have been encouraged to diagnose and treat high blood pressure more effectively. Between 2003 and 2011, the number of individuals with undiagnosed hypertension fell from 33 percent to 24 percent. Additionally, the average systolic blood pressure for the population decreased from 129 mm Hg to 124 mm Hg. Yet, from 2019 onward, these improvements stalled, largely attributed to rising obesity levels and unhealthy dietary habits.

Dr. Ajay Gupta, a consultant in cardiovascular medicine at Queen Mary University of London and lead researcher of the study, suggests that increased salt consumption and lifestyle changes have contributed to rising blood pressure rates. Following a decade of successful salt reduction efforts, average intake rose to 8.4 grams per person daily by 2018, exceeding the recommended maximum of 6 grams. Processed foods, which often contain high salt levels, are increasingly prevalent in diets, further complicating hypertension management.

COVID-19’s Role in Hypertension Care

The onset of the COVID-19 pandemic in 2020 disrupted regular healthcare services, making it difficult for patients to consult their general practitioners (GPs) for routine checks and adjustments to their hypertension treatment. Dr. Gupta pointed out that many people missed vital health evaluations, which could have identified high blood pressure early on. By the time the next health survey was conducted in 2021, the percentage of individuals with undiagnosed hypertension had risen to 32 percent, with average systolic blood pressure climbing to 126 mm Hg.

Preliminary data from 2022 suggests minimal improvement in blood pressure management since the previous year, indicating that the situation remains precarious. The ongoing rise in obesity, coupled with increased pressure on primary care services, implies that blood pressure control has yet to recover to pre-pandemic levels. Professor Wilkinson highlights the importance of addressing these trends, stating, “The population is getting heavier, and that is one of the strongest risk factors for hypertension.”

The shift towards remote consultations during the pandemic may also contribute to the reluctance of some patients to initiate blood pressure treatment. Many individuals do not experience noticeable symptoms of hypertension, leading to hesitance in beginning medication. Professor Wilkinson noted that having meaningful conversations with healthcare providers can motivate patients to adhere to treatment plans, emphasizing the long-term health benefits of early intervention.

As the NHS continues to grapple with these challenges, the need for renewed focus on hypertension management and public health education is clear. Without significant changes, the health of the population may remain at risk, underscoring the urgency for comprehensive strategies to improve blood pressure control across the UK.
