Eating Disorder Statistics in the UK: Evidence, Trends, and Key Findings

Eating disorder statistics

Eating disorders are serious mental health conditions that can affect people of any age or background. They can have significant physical consequences, but treatment and recovery are possible.

Reviewed 15 October 2026. The figures below separate UK estimates, England survey results and NHS service measures, which answer different questions.

Prevalence

Beat’s July 2026 estimate is around 3.5 million people in the UK — about 1 in 20. It uses England surveys and modelling assumptions rather than a UK diagnostic census.
In England’s 2023/24 Adult Psychiatric Morbidity Survey, 9.1% of adults screened positive for a possible eating disorder, compared with 6.4% in 2007. A positive screen is not a diagnosis.
Screening was positive for 11.8% of women and 6.1% of men. These are rates within each group, not the sex distribution of all cases.
A separate diagnostic assessment estimated a past-year eating disorder in 1.3% of adults (95% confidence interval 0.8%–2.2%). The screen-plus-assessment method used 26 positive cases; the report warns that it may underestimate prevalence.

Impact on health services

NHS England reports 11,174 children and young people starting eating-disorder treatment in 2024/25, compared with 8,034 in 2019/20 — an increase of about 39%.
These figures count starts of treatment in the reported services, not everyone living with an eating disorder.
Service demand and prevalence are different measures: referral practices, access and identification can also affect the number receiving care.

People seeking professional treatment

In the three months ending August 2026, 78.8% of urgent eating-disorder referrals for under-18s entering treatment in England were seen within one week.
For routine referrals, 81.4% were seen within four weeks in the same three-month period.
Both measures were below the 95% national standard. They measure waiting after referral, not years between the first symptoms and seeking help.
NICE recommends early assessment and treatment. Someone concerned about eating or related behaviours should seek help without waiting to meet a particular weight or severity threshold.

Mortality and outcomes

Eating disorders can lead to serious physical complications and mental health difficulties. Clinical risk depends on the person’s current condition and needs, rather than a single population percentage.
Recovery is possible. Treatment is tailored to the eating disorder and the person’s physical and psychological needs; early support can improve outcomes.

Family history and risk factors

The NHS identifies family history of an eating disorder or certain other mental health problems as a possible risk factor. This does not mean that an eating disorder is inevitable.
There is no single known cause. Psychological and social experiences can also contribute, so one genetic percentage or family-risk multiplier cannot explain every person’s experience.

Trends

The change from Beat’s older 1.25 million estimate to 3.5 million is not a directly comparable increase; the surveys, diagnostic definitions and estimation methods differ.
The England adult screening comparison provides evidence of change over time, while the small diagnostic sample limits detailed breakdowns.
Statistics on anorexia, bulimia, binge-eating disorder and avoidant/restrictive food intake disorder (ARFID) should not be combined without checking which conditions and populations a study includes.

What these eating disorder statistics tell us

The evidence shows substantial need and gaps in timely access to treatment. Read each figure with its population, year and definition: possible symptoms, a clinical diagnosis and a treatment episode are not interchangeable.

Frequently asked questions about eating disorders

How common are eating disorders in the UK?

Beat’s July 2026 model estimates around 3.5 million people, or 1 in 20. It extrapolates England surveys to the UK and adjusts for screening accuracy; it is not a count of diagnosed patients.

Are eating disorders increasing?

The England adult survey recorded positive screening in 9.1% of adults in 2023/24 compared with 6.4% in 2007. Screening is not diagnosis. Beat’s new UK estimate cannot be directly compared with its old 1.25 million estimate because the methods changed.

Which eating disorder has the highest mortality rate?

A single ranking does not describe an individual’s risk. Eating disorders can cause serious physical and mental health complications, and prompt assessment matters whatever the diagnosis. Recovery is possible with treatment.

How long do people wait for eating disorder treatment?

For under-18 eating-disorder referrals entering treatment in England in the three months ending August 2026, 78.8% of urgent referrals were seen within one week and 81.4% of routine referrals within four weeks. These service measures do not measure time from the first symptoms or describe all adult services.

Are eating disorders genetic?

There is no single known cause. Family history can be a risk factor, alongside psychological, social and other influences. A family history does not mean someone will necessarily develop an eating disorder.

Are men affected by eating disorders?

Yes. Eating disorders can affect people of any sex or gender. England’s 2023/24 adult survey found positive screening in 6.1% of men and 11.8% of women; these are screening rates within each group, not the gender split of diagnosed cases.

How these statistics were sourced

This review uses NHS survey and service publications, NICE guidance and Beat’s published estimate and methodology. The adult survey covers people aged 16 and over in private households in England; Beat extrapolates to the UK and adjusts screening results, with acknowledged uncertainty. Service waiting-time percentages cover children and young people in England.

If you or someone you care about is affected

Speak to a GP if you are worried about your eating or someone else’s. You do not need to be certain of a diagnosis before asking for help. A GP can assess health needs and arrange specialist support where appropriate. Beat also provides information and support for people affected and their families.
