More than a million people in England are set to gain access to a powerful weight-loss drug, semaglutide, as part of a new initiative aimed at significantly reducing the risk of heart attacks and strokes. The National Institute for Health and Care Excellence (NICE) has given the green light to expand eligibility for the medication, commonly known as Wegovy, to individuals who are overweight – not necessarily obese – and have a history of cardiovascular events. This marks a shift in how the National Health Service (NHS) approaches preventative cardiovascular care, recognizing the benefits of semaglutide extend beyond weight management.
The decision, announced Wednesday, is based on compelling evidence from clinical trials, including a landmark study led by University College London (UCL). These trials demonstrated that semaglutide reduces the risk of major cardiovascular events, such as heart attack and stroke, even *before* substantial weight loss occurs. This suggests the drug has a direct protective effect on the heart and blood vessels, independent of its impact on body weight. The move is expected to benefit approximately 1.2 million people in England, offering a new layer of protection for those living with the fear of another life-threatening cardiac or cerebrovascular event.
Expanding Access to Semaglutide: Who Qualifies?
Currently, semaglutide is available on the NHS under the brand name Wegovy for some individuals with obesity, and as Ozempic for the treatment of type 2 diabetes. The new guidance from NICE broadens access to include people with a body mass index (BMI) of 27 or higher who have experienced a heart attack, stroke, or serious circulation problems in their legs. This expansion acknowledges that cardiovascular risk isn’t solely tied to obesity, and that individuals with a lower BMI can still benefit from the drug’s protective effects. The NHS states that the medication will be offered alongside existing treatments, such as statins, and in conjunction with lifestyle modifications like a reduced-calorie diet and increased physical activity.
How Semaglutide Works: Beyond Weight Loss
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, originally developed to manage type 2 diabetes. It works by mimicking the effects of a natural hormone that regulates appetite and blood sugar levels. While its weight-loss effects are well-known – and have driven significant demand for the drug – recent research has highlighted its independent cardiovascular benefits. The study published in The Lancet showed a significant reduction in the risk of cardiovascular events, regardless of the amount of weight lost by participants.
“What we have is a really exciting development,” says Riyaz Patel, a professor of cardiology at UCL. “It gives us another powerful tool to reduce cardiovascular disease risk.” He similarly cautioned that questions remain regarding the NHS’s capacity to deliver the drug to such a large population.
Clinical Trial Results and Expert Reactions
Previous analysis had already indicated that semaglutide could reduce the risk of major cardiac events by as much as 20%. Reporting in May 2024, researchers found this benefit was consistent across a range of patients. The more recent UCL study, however, solidified the understanding that the drug’s benefits aren’t solely tied to weight loss. Helen Knight, director of medicines evaluation at NICE, described the evidence from the UCL study as “compelling,” noting that patients taking semaglutide alongside existing heart medications were “significantly less likely” to experience another heart attack or stroke.
Dr. Sonya Babu-Narayan, clinical director of the British Heart Foundation, emphasized that semaglutide has “proven benefits beyond reducing the number on the scales” and that weight-loss drugs are now considered “important medicines” for preventing cardiovascular events. Professor Naveed Sattar, professor of cardiometabolic medicine at the University of Glasgow, echoed this sentiment, calling the decision “extremely good news” stemming from “high-quality trial evidence.”
Implementation and Potential Challenges
While the NICE guidance is currently draft, NHS England officials have stated that eligible patients will be able to access semaglutide “within months.” However, the rollout may face logistical challenges. Supply chain issues have previously hampered access to Wegovy, as reported by The Guardian in September 2023. Ensuring sufficient supply to meet the needs of 1.2 million potentially eligible individuals will be crucial. The NHS will need to establish clear pathways for identifying and referring appropriate patients, and to provide the necessary support for lifestyle changes that complement the medication’s effects.
Health Minister Sharon Hodgson hailed weight-loss drugs as a “gamechanger” and predicted they would be a “lifesaver” for those at risk. The NHS is optimistic that, alongside healthy lifestyle choices, semaglutide will prevent thousands of future cardiovascular events and improve the quality of life for many.

The NHS plans to begin rolling out access to semaglutide in the coming months, with ongoing monitoring of supply and implementation. Further updates and guidance for healthcare professionals will be released by NHS England as the program progresses.
