Given that eating disorders are a growing public health crisis, asks why research is still neglected.
Eating disorders carry the highest mortality rate of any psychiatric condition and are impacting a growing number of people in the UK, with increasingly complicated conditions. So, it will come as a surprise to hear there is a persistent lack of funding available for research into these conditions.
In 2026, the scale of the challenge is no longer in question. The social and economic cost of mental health conditions is estimated at £300 billion annually, and the UK is estimated to spend around £9 billion each year dealing with the consequences of eating disorders.
Despite these huge costs, the latest estimates show research into mental health conditions remains chronically underfunded, receiving just 6.1% of the annual research budget. This is especially stark as eating disorders receive only 1% of total mental health research funding.
At least 1.25 million people are living with eating disorders, making them a major public health issue across all demographic groups, and this imbalance sits uneasily alongside rising demand for services and increasing wait times.
Mounting pressure
Recent NHS data shows a system under mounting pressure. Referrals to eating disorder services have increased by around 50% in recent years, reflecting both greater awareness and a genuine rise in need. Hospital admissions linked to eating disorders have also risen sharply, increasing by around 84% over the past decade.
Access to support for children and young people has expanded in response, improving access in many areas, although analysis found earlier this year that ICBs in England are planning cuts worth £2.1 million to these services.
The picture for adults poses further challenges, with significant differences in waiting times and service availability depending on location. In the most severe cases, adult patients are still waiting up to 700 days for treatment. Even where averages are lower, delays are often long enough for conditions to become more entrenched, medically complex and harder to treat, making recovery increasingly difficult.
Early intervention remains one of the strongest predictors of recovery. The longer an eating disorder goes untreated, the more likely it is to become embedded in behaviour and identity. Too often, the system responds only once crisis has already developed.
Part of the problem lies in how eating disorders have historically been understood. For years, they were mischaracterised as lifestyle issues or passing phases rather than serious psychiatric illnesses with some of the highest mortality rates in mental health. Clinical understanding has evolved, but funding and service structures have not kept pace.
Research remains one of the clearest gaps. With only 1% of mental health research funding directed towards eating disorders, the evidence base has developed more slowly than the scale of need demands. This affects everything from identifying early warning signs to preventing relapse and tailoring treatment pathways. When research is limited, services are left responding without the full benefit of evolving evidence.
Research funding matters because it shapes not only future treatment, but the quality of care available today. Many of the approaches currently used in eating disorder services were developed years ago, despite the profile of patients becoming increasingly complex. Clinicians are now seeing higher levels of co-occurring conditions, including anxiety, depression, autism and trauma-related disorders, yet research into how these factors interact with eating disorders remains limited.
Without sustained investment, progress slows across every stage of the care pathway. Opportunities to improve early diagnosis are missed, new treatment models take longer to develop and evaluate, and promising interventions struggle to move beyond small pilot programmes into wider NHS adoption. Research is also critical to understanding why relapse rates remain high and which approaches lead to the most sustainable long-term recovery.
The funding gap also affects who gets recognised and diagnosed. Eating disorders continue to be underdiagnosed in men, older adults and people from ethnic minority backgrounds, partly because research has historically focused on narrow patient profiles. Better funded and more inclusive research could help services identify people earlier and respond more effectively to the full diversity of those affected.
Inconsistent access
The result is a system where access is inconsistent, waiting times can be extreme, and outcomes depend heavily on timing and geography. For some people, care arrives early enough to make a meaningful difference. For others, treatment begins only after the illness has become far more severe and difficult to address.
Community is often discussed in the context of recovery, and rightly so. But there also needs to be a broader sense of collective responsibility at system level. When conditions affect more than a million people and cost billions each year, they require sustained and coordinated attention.
The £9 billion annual cost of eating disorders is often framed as an economic figure, but it also reflects something deeper. It is the cost of delayed care, fragmented pathways and underinvestment in research.
The evidence is already clear. Eating disorders are among the most serious and deadly mental health conditions, yet they continue to sit at the margins of funding and policy. The question now is whether the UK is prepared to respond with the urgency and sustained funding needed.
