The state of diabetes care in the UK
More than four million people in the UK live with diabetes, and that number keeps climbing. Most manage the condition day to day with tablets, insulin or both, and many still rely on finger prick testing to check blood glucose. The result is a familiar strain: constant decisions, worry about hypos, and a condition that never takes a holiday.
Three pain points come up again and again. The burden of monitoring is the first. Finger prick tests give snapshots, not the full picture, so overnight dips go unseen and trends stay invisible. The second is diabetes distress. The emotional load is real, and many people feel judged or overwhelmed by the daily routine. The third is uneven access. Depending on where you live, some patients get newer technology while others wait, which is exactly why research matters so much.
That is where diabetes management trials in the UK come in. The research network spans NHS trusts, universities and industry partners, and 2026 has already delivered some notable results.
What the trials are testing
Continuous glucose monitoring for type 2 diabetes
The biggest headline this year is the FreeDM2 trial, led by teams at the University of Nottingham, University Hospitals of Derby and Burton, and Imperial College London. It compared real-time continuous glucose monitoring with traditional finger prick testing in adults with type 2 diabetes who use basal insulin. Results published in The Lancet Diabetes and Endocrinology showed that CGM meaningfully improved glucose control. The team presented the findings at the Diabetes UK Professional Conference in Liverpool.
For people who have struggled to keep blood glucose in range, this points to a future where more type 2 patients could be offered the technology, not just those on intensive insulin regimes.
Simpler dietary answers
Not every trial is about devices. The GLOWING study at the University of Birmingham is recruiting adults aged 70 to 90 with type 2 diabetes to test whether whey protein drinks taken before meals can smooth out blood sugar responses. Participants receive the supplements to use at home over two seven-day periods. It is a small, practical idea with the potential to help older adults who want gentler options.
Support for the mind as well as the body
Researchers at the University of the West of England are running a feasibility study of a four-week self-guided digital programme for adults with type 1 or type 2 diabetes, aimed at reducing diabetes distress. Participation is online, which opens the door for people in remote parts of Scotland, Wales and Northern Ireland who cannot easily travel to a research clinic.
Early work and specialist studies
Elsewhere, the Address 2 study at Berkshire Healthcare NHS Foundation Trust is looking at people newly diagnosed with type 1 diabetes and their siblings, with the goal of understanding the condition better and improving earlier detection. In Leeds, a team is testing better glucose control for patients with diabetes going into surgery, a group that is often overlooked. And in Birmingham, Blackpool, Bristol, Bromborough and Newcastle, an industry-backed phase two study is evaluating a new investigational medicine alongside standard care for type 2 diabetes.
A closer look at the options
| Trial type | Example in the UK | Who it suits | What it involves | Main benefits | Things to weigh up |
|---|
| Continuous glucose monitoring | FreeDM2, Nottingham, Derby and London | Adults with type 2 diabetes on basal insulin | Wearing a small sensor for up to two weeks with regular app check-ins | Trend data instead of isolated readings; better control shown in the trial | Some people find the sensor intrusive at first |
| Dietary intervention | GLOWING, University of Birmingham | Adults aged 70 to 90 with type 2 diabetes | Taking a whey protein drink before meals for two seven-day periods at home | Simple, food-based and low burden | Not suitable for anyone with a dairy allergy |
| Digital wellbeing programme | UWE Bristol feasibility study | Adults with type 1 or type 2 diabetes | Four-week online programme completed at your own pace | Accessible anywhere; targets diabetes distress | Feasibility stage, so results are still emerging |
| Family and early detection | Address 2, Berkshire Healthcare NHS Trust | People recently diagnosed with type 1 and their siblings | Questionnaires plus optional blood samples | Supports earlier detection and better understanding | Optional parts require a clinic visit |
| Investigational medicine | Phase two study, Birmingham, Blackpool, Bristol, Bromborough, Newcastle | Adults with type 2 diabetes on stable treatment | Taking an investigational treatment alongside current medication | Access to emerging therapies under close supervision | Requires commitment to scheduled visits |
How to get involved
Taking part in a trial is a personal decision, and nobody should feel pressured. If you are curious, start with your diabetes team. Your GP or specialist can tell you whether your local NHS trust has research open, and they know your history better than any website.
Alongside that, use the official portals. Diabetes UK runs a take part in research page that lists open studies by location and condition. The NIHR Be Part of Research service does the same across England, and equivalent schemes exist in Scotland, Wales and Northern Ireland. Search for something like diabetes management trials UK or filter by your nearest city.
The registries are worth a look too. ClinicalTrials.gov and the ISRCTN registry are the public record for most studies, with each listing explaining the purpose, the number of visits and the inclusion criteria. You can see at a glance whether you might be eligible.
Before you sign up, ask practical questions. How many visits? Is it online or in person? Are travel expenses covered? Will you still see your usual diabetes nurse? Good studies welcome these questions, and the research team should answer them clearly. Participation is voluntary, and you can withdraw at any time without affecting your routine care. Many people join because they want to give back and help others, and support usually reflects reasonable travel and time rather than being a payment.
A participant in the FreeDM2 trial from Derby described the sensor as far less bother than she expected, and said the daily trends helped her see exactly which meals caused spikes. Stories like that, repeated across the country, are why recruitment matters.
The road ahead
The trials running in 2026 are not isolated projects. They are pieces of a bigger conversation about how the UK cares for the millions of people expected to live with diabetes in the coming years. If the CGM evidence holds, more type 2 patients could see the technology on prescription. If the GLOWING results are positive, protein drinks before meals might become a standard, low-cost recommendation for older adults. If digital programmes reduce distress, they could reach people who never visit a clinic.
The most direct way to shape that future is to take part. Talk to your diabetes team this month, look at the Diabetes UK research page, and ask what is recruiting near you. The next breakthrough in diabetes management trials in the UK could easily be the one you help to prove.
