A record number of people in England have taken steps to avoid type 2 diabetes by joining an NHS prevention programme, new data reveals.
The NHS Healthier You initiative offers nine months of personalised support focused on healthy eating and staying active. It aims to delay or prevent the onset of type 2 diabetes. Researchers at the University of Manchester found that completing the programme can reduce the risk of developing the condition by up to 37%.
In 2023, 166,360 adults enrolled in the scheme—the highest number since it launched in 2016. In total, more than 900,000 high-risk individuals have now used the programme.
Type 2 diabetes occurs when the body does not produce enough insulin, or when insulin stops working properly. This leads to high blood sugar levels, which can cause serious health problems if untreated. Obesity is the biggest risk factor, but family history, ethnicity, and low activity levels also play a role. Symptoms often include fatigue, increased thirst, and frequent urination.
Health Minister Ashley Dalton welcomed the rise in participation. “We know prevention is better than treatment. Tackling the root causes of diabetes, like poor diet and inactivity, is key to reducing related health issues. This programme is helping people make small, lasting lifestyle changes that can have a big impact,” she said.
Around 4.8 million people in the UK are currently living with diabetes—diagnosed or not. The condition costs the NHS an estimated £10.7 billion each year.
Douglas Twenefour, head of clinical services at Diabetes UK, called the NHS scheme “vital” for helping people at high risk avoid serious complications. “It’s encouraging to see so many accessing this life-changing support,” he said.
Dr Clare Hambling, National Clinical Director for Diabetes and Obesity at NHS England, added that type 2 diabetes and obesity remain major public health challenges. “This programme is not only preventing diabetes, but also helping people live healthier lives,” she said. “It’s important to know your risk. The NHS ‘Know Your Risk’ tool is a quick way to find out, or you can talk to your GP.”
