The State of Diabetes Research in the UK
Diabetes touches roughly five million people in the United Kingdom, most of them living with type 2 diabetes. That scale is exactly why so many trials exist here. The country has a long track record in this field, stretching back to the landmark UK Prospective Diabetes Study, which ran across 23 clinical sites for two decades and proved that tighter glucose control genuinely reduces complications. That legacy still shapes how research is designed today.
What makes the current moment interesting is the range of approaches. Traditional drug trials remain a core part of the picture. An industry-sponsored phase 2 study, for instance, is currently recruiting participants with type 2 diabetes across Birmingham, Blackpool, Bristol, Bromborough, and Newcastle, comparing a new treatment against placebo in people already on a stable dose of semaglutide or tirzepatide. Meanwhile, universities are exploring lifestyle interventions, from pre-meal whey protein drinks for older adults at the University of Birmingham to a beetroot juice study at Oxford Brookes examining cardiovascular responses after exercise.
There is also a strong digital thread running through UK research. The University of the West of England is recruiting adults with either type 1 or type 2 diabetes for a four-week online programme aimed at emotional wellbeing, while Sheffield researchers have been interviewing patients about how digital tools can support people living with diabetes and depression.
What Participating in a Trial Actually Involves
For many people, the idea of a clinical trial conjures up images of hospital wards and needles. In reality, the experience varies enormously depending on the study.
Some trials are entirely online. Questionnaires, app-based monitoring, and remote consultations mean you might never set foot in a research centre. Others are more hands-on. The GLOWING study at Birmingham, for example, requires a screening visit to the School of Sport, Exercise and Rehabilitation Sciences, followed by taking two supplements at home before meals over two seven-day periods. The beetroot juice study at Oxford Brookes involves two laboratory visits with light cycling, blood pressure readings, and blood sugar testing.
Technology trials often bring participants into closer contact with new devices. A real-world study using the feature-simplified Dexcom ONE continuous glucose monitoring system demonstrated significant improvements in HbA1c among a socioeconomically diverse group of adults, suggesting that CGM could benefit a broader population than NICE guidelines currently identify. A separate pragmatic randomised controlled trial is examining whether FreeStyle Libre 3 improves HbA1c compared with traditional finger-prick testing in adults with sub-optimally controlled type 2 diabetes on basal insulin.
Table: A Snapshot of UK Diabetes Trials and Programmes
| Trial or Programme | Focus | Typical Commitment | Location | Potential Benefit |
|---|
| Eli Lilly phase 2 study | New treatment vs placebo alongside GLP-1 therapy | Regular clinic visits over trial period | Birmingham, Blackpool, Bristol, Bromborough, Newcastle | Access to emerging medication |
| GLOWING (whey protein) | Pre-meal protein drinks for adults 70-90 | Screening visit plus two 7-day home periods | Birmingham | Insight into meal-based glucose management |
| Oxford Brookes beetroot study | Cardiovascular response to beetroot juice | One online screening, two lab visits | Oxford | Personal health measurements |
| UWE Bristol digital wellbeing | Self-guided emotional support programme | Four weeks, fully online | Nationwide (online) | Better emotional coping skills |
| CGM trials (Dexcom ONE, Libre 3) | Continuous glucose monitoring vs finger-prick | Device wear over 16-32 weeks | Various UK sites | Improved glucose control and fewer finger pricks |
| NHS Type 2 Diabetes Path to Remission | Soup and shake diet programme | Structured plan, typically around a year | England-wide via GP referral | Weight loss and possible remission |
The NHS Type 2 Diabetes Path to Remission Programme deserves a special mention, even though it is a treatment pathway rather than a research trial. Real-world data has shown that a third of participants who completed the programme achieved remission from type 2 diabetes within a year. More than 13,000 people were enrolled onto it last year alone, and eligibility includes adults aged 18 to 65 diagnosed with type 2 diabetes within the last six years, with a BMI over 27 for White ethnic groups or over 25 for other groups. Referrals come through GP practices.
How to Find and Join a Trial Near You
Finding the right study does not have to be complicated. Diabetes UK runs a dedicated "take part in research" section on its website, which lists active studies with clear descriptions of what participation involves, whether they are online or in-person, and what dates they run. This is usually the best starting point for anyone who wants to match themselves to a study.
Clinical trial registries are another route. The ClinicalTrials.gov database and the ISRCTN registry both allow you to search by condition and location, and you can filter for studies that are actively recruiting in the UK. The NHS also advertises research opportunities through local trusts and research nurses, so it is worth asking at your next diabetes appointment. Many people are surprised to learn that their own hospital may already be running a study relevant to their condition.
Before you commit to anything, a few practical points are worth bearing in mind. Eligibility criteria matter, so be honest about your full medical history. Make sure you understand whether travel costs and any out-of-pocket expenses are covered, as this varies between studies. And never feel pressured. Participation is voluntary, and you can withdraw at any point without it affecting your usual NHS care.
What the Future of UK Diabetes Research Looks Like
The direction of travel in the UK is clear. Technology is moving from specialist clinics into everyday care, most visibly with the rollout of hybrid closed loop systems, sometimes described as an artificial pancreas, for people with type 1 diabetes. NHS England has described this as a world first, and it has already transformed daily life for participants like Gemma Lavery from Plymouth, who no longer worries about work stress spiking her glucose levels overnight.
For type 2 diabetes, the emphasis is increasingly on remission rather than lifelong management. The record numbers joining the soups and shakes programme suggest that weight-based approaches are becoming mainstream, and researchers are exploring how medication, technology, and lifestyle changes can work together more effectively.
If you are curious about what research could offer you, the best approach is simple. Speak to your GP or diabetes specialist, browse the Diabetes UK research pages, and see whether a study matches your situation. Even a modest commitment, like a few online questionnaires or a short lab visit, can contribute to knowledge that helps thousands of others living with diabetes across the United Kingdom.
