Eating Disorders Treatment Statistics

Most people with eating disorders never receive treatment. An updated systematic review and meta-analysis found that roughly 30% of affected individuals seek help from any source, and about 32% seek formal treatment from a health professional specifically for eating disorder concerns.¹ That means close to two-thirds of people suffering from these conditions are doing so without professional support. The numbers get more sobering from there, because even among those who do enter treatment, recovery rates vary dramatically depending on the specific disorder, the type of therapy, and how quickly someone gets help.

The Treatment Gap Across Different Disorders

The gap between who needs treatment and who gets it is not uniform. A study of women with eating disorder symptoms found that about 11% of the full sample had received treatment. When broken down by symptom profile, treatment rates ranged from 11% among women with binge eating behaviors or other specified feeding or eating disorder symptoms up to 43% among women with bulimic behaviors.² Only about one in five women with anorexia nervosa symptoms had received treatment, despite anorexia being the eating disorder most commonly depicted in media and clinical training.

These treatment-seeking patterns are somewhat counterintuitive. You might expect that the most medically dangerous disorder would have the highest treatment rates, but it does not. The disorders that are more visible to others or that cause acute behavioral distress, like binge-purge cycles, seem to push people toward help more than the restrictive patterns that can look, from the outside, like disciplined eating. The result is a large population of people with clinically significant symptoms who never enter a therapist’s office or a treatment program.

Why People Do Not Seek Help

Stigma is the most consistent barrier across all eating disorder diagnoses. A study examining perceived barriers to treatment-seeking found no significant differences between diagnostic groups in the types of barriers experienced, but stigma was rated as the most impactful barrier for every group studied.³ That stigma takes different forms: shame about the behaviors themselves, fear of being judged for having a “vanity” problem, worry that others won’t believe the eating disorder is real (particularly among men and people in larger bodies), and reluctance to disrupt family relationships by disclosing the illness.

Financial barriers are also enormous. A U.S. study found that lack of insurance coverage was the single most frequently reported barrier to treatment access.⁴ People with historically underrepresented identities and those with OSFED, the most common and least recognized category, reported more barriers related to finances, geography, sociocultural factors, and treatment quality than white and cisgender participants. The more barriers people reported, the more severe their symptoms were and the worse their illness trajectories became, creating a vicious cycle where the people most in need of help were the least likely to reach it.

For Latina women in the United States, additional barriers include a lack of information about eating disorders in their communities and the scarcity of bilingual treatment options. Family privacy norms and the fear of not being understood culturally also delay help-seeking.⁵

How Effective Are the Main Treatments

Treatment effectiveness depends heavily on the diagnosis. The best-supported therapy for adolescents with anorexia nervosa is family-based treatment, sometimes called FBT or the Maudsley approach, which positions parents as active agents in their child’s re-feeding and recovery. The evidence supports its use, but recovery rates are only around 40%, and less than half of young people achieve full recovery by the end of a standard course of treatment.⁶ ⁷ That is a sobering number for the gold-standard treatment. It means the majority of adolescents who complete the best available therapy still have significant symptoms at the end.

For bulimia nervosa and binge eating disorder, cognitive-behavioral therapy is the most studied approach. A meta-analysis of 36 trials found that CBT produced an overall abstinence rate of about 36%, compared to roughly 10% in control conditions.⁸ Another meta-analysis found that the remission rate of CBT for binge eating disorder was 50%, higher than for bulimia (28%) or anorexia (33%).⁹ CBT clearly outperforms doing nothing, but the numbers tell you that a large group of patients do not respond sufficiently to it.

One landmark comparison of CBT and interpersonal therapy for bulimia nervosa found that CBT was far superior at the end of active treatment, with 29% of CBT participants recovered compared to 6% for interpersonal therapy. But at follow-up, the gap closed substantially, with about 40% of CBT completers recovered compared to 27% for interpersonal therapy, a difference that was no longer statistically significant.¹⁰ That tells you something important: the speed of improvement differs between therapies, but people can continue improving after active treatment ends.

Recovery Takes Longer Than Most People Expect

One of the most striking statistics in eating disorders research comes from a 22-year follow-up study. At nine years, only about 31% of people with anorexia nervosa had recovered. By 22 years, that figure had climbed to nearly 63%. Roughly half the people who had not recovered by the nine-year mark eventually did so over the following 13 years.¹¹ For bulimia nervosa, the recovery rate was about 68% at both the 9- and 22-year marks, suggesting most recovery from bulimia happens earlier or not at all.

Early recovery in anorexia was strongly associated with long-term recovery, with people who recovered early being about ten times more likely to remain recovered at the long follow-up. But the converse is encouraging rather than discouraging: even people who had not recovered after nearly a decade still had a meaningful chance of getting better. The clinical message is that neither patients nor clinicians should give up on recovery after a few years of illness.

Relapse, however, is common across diagnoses. A cohort study of patients who completed a relapse-prevention program for anorexia found that 11% experienced a full relapse and another 19% a partial relapse, with the highest risk window falling between months four and sixteen after the program.¹² For bulimia nervosa, the numbers are starker: one naturalistic study found a 63% cumulative probability of relapse by about 18 months after recovery, and half of people who recovered from one episode relapsed into another.¹³

Mortality and Medical Seriousness

Eating disorders carry the highest mortality risk of any psychiatric condition. An updated meta-analysis covering studies from 2010 to 2024 found that mortality was highest for anorexia nervosa, where the standardized mortality ratio was about 5.2, meaning people with anorexia die at over five times the rate of the general population.¹⁴ An earlier meta-analysis of 36 studies reported an even higher figure, with a standardized mortality ratio of about 5.9 for anorexia nervosa and an annual mortality rate of roughly 5 deaths per 1,000 person-years, of which about one quarter resulted from suicide.¹⁵

Bulimia nervosa and OSFED also carry elevated mortality risks, though at lower magnitudes. Binge eating disorder shows a more modest increase. There is some evidence that the risk of premature death among people with anorexia is concentrated in certain windows. One longitudinal study found that the annual mortality rate was about 5.5 deaths per 1,000 person-years in the first decade of follow-up but dropped to roughly 1.1 per 1,000 in the second decade. However, people with longer illness duration (more than 15 years) had a higher standardized mortality ratio than those who had been ill for less than 15 years.¹⁶ Chronic illness is more dangerous, which reinforces the urgency of early and sustained treatment.

Disparities in Who Gets Treated

The treatment gap is not distributed evenly across the population. Among college students with eating disorder symptoms, women were about twice as likely as men to perceive a need for treatment and nearly five times more likely to receive a diagnosis. Students from affluent backgrounds had roughly twice the odds of receiving treatment compared to their less affluent peers.¹⁷ The stereotype that eating disorders primarily affect thin, white, affluent young women shapes who gets identified, who gets diagnosed, and who gets treated, leaving everyone who doesn’t fit that profile at a disadvantage.

Insurance type also matters enormously. A study of youth found that patients with public insurance were about a third as likely to receive recommended treatment as those with private insurance, after adjusting for clinical and demographic differences. Latinx patients were about half as likely as white patients to receive recommended treatment, and Asian patients faced a similar disparity.¹⁸ These gaps exist even when researchers account for the severity of the illness, which means they reflect systemic access problems rather than differences in clinical need.

Dropping Out of Treatment

Even among people who begin treatment, a large fraction do not finish. A comprehensive literature review found dropout rates ranging from about 20% to 51% in inpatient settings and from 29% to 73% in outpatient settings.¹⁹ The most consistent predictor of dropout was having the binge-purge subtype of anorexia nervosa. Clinical severity at baseline, surprisingly, was not a reliable predictor.

A meta-analysis focused specifically on CBT for eating disorders estimated an overall dropout rate of about 24%, with internet-based CBT showing the highest dropout and the enhanced transdiagnostic version of CBT showing the lowest. Longer treatment protocols were associated with lower dropout, possibly because they allow more time to build a working relationship and see meaningful change before asking someone to commit to the process fully.²⁰

The Economic Burden

Eating disorders cost the United States an estimated $64.7 billion in the 2018–2019 fiscal year, which works out to roughly $11,800 per affected person. OSFED accounted for 35% of total costs, followed by binge eating disorder at 30%, bulimia nervosa at 18%, and anorexia nervosa at 17%.²¹ The overwhelming majority of those costs, more than 90%, came from indirect costs like lost productivity, absenteeism, and reduced work capacity rather than direct medical spending.²²

At the individual level, yearly healthcare costs for people with eating disorders are about 48% higher than the general population, and mental health comorbidity is associated with about 48% lower annual earnings.²³ These figures underline something that health policy often misses: eating disorders are not just a personal struggle. They are an economic problem with measurable costs to employers, families, and health systems.

What Inpatient Versus Outpatient Care Actually Shows

There is a widespread assumption that more intensive treatment is always better, but the evidence does not clearly support that. A Cochrane review found that for anorexia nervosa, there may be little or no difference in weight gain at 12 months between specialist inpatient care and active outpatient or combined brief hospital-and-outpatient care. People randomized to outpatient settings may actually be more likely to complete treatment, though the quality of evidence was low.²⁴ Outpatient care is also less disruptive, less expensive, and tends to have shorter waiting lists.²⁵

This does not mean inpatient care is unnecessary. Medical instability, suicidal ideation, and extreme malnutrition may require hospitalization. But for patients who are medically stable, starting with outpatient treatment rather than waiting for an inpatient bed is often the better path, both clinically and practically.

Medication for Binge Eating Disorder

Binge eating disorder is the one eating disorder with a medication specifically approved for its treatment. Lisdexamfetamine showed clear superiority over placebo in randomized clinical trials, with treated patients far less likely to relapse. In one trial, just under 4% of people continuing on the medication met relapse criteria, compared to about 32% of those switched to placebo.²⁶ ²⁷

An open question is what happens when people stop the medication. Early case evidence suggests that gradual tapering within the context of ongoing psychotherapy can prevent relapse, with treatment gains sustained as long as five years after discontinuation in some patients.²⁸ But this remains an area where the research is thin, and most clinicians navigate medication discontinuation without strong guidance.

Early Intervention Makes a Measurable Difference

An early-intervention program in the UK called FREED (First Episode Rapid Early Intervention for Eating Disorders) offers some of the most encouraging data in the field. Among patients with anorexia nervosa, about 53% reached a healthy weight at 12 months, compared to only 18% of patients receiving treatment as usual. Fewer FREED patients required intensive care like inpatient admission, and the program trended toward cost savings.²⁹ The evidence is consistent across multiple studies: the predictors of better treatment outcomes include higher body weight at baseline, fewer binge-purge behaviors, greater motivation to recover, lower depression, and fewer comorbidities.³⁰ In other words, the earlier and less entrenched the illness, the better the response to treatment.

Having co-occurring mental health conditions like anxiety or depression does not necessarily mean worse outcomes, but it does mean longer treatment. A study from a community mental health service found that patients with comorbidities achieved similar recovery rates to those without, but their treatment episodes were significantly longer.³¹ Systems that set rigid session limits may inadvertently disadvantage the people who need the most time.

Telehealth and Expanding Access

One of the few silver linings of the pandemic era has been the accelerated adoption of telehealth for eating disorder treatment. Virtual delivery of family-based treatment has shown promising results in rural settings, where access to specialized eating disorder care has traditionally been almost nonexistent. A multi-site feasibility study found that over 68% of adolescents treated with telehealth-based FBT achieved weight restoration, and about 37% met both weight and psychological remission criteria. Weight improvements were maintained at six-month follow-up.³²

A larger study of young patients receiving virtual FBT found that those on weight restoration gained an average of about 11 pounds over 16 weeks, with reductions in eating disorder symptoms, depression, and anxiety. Caregiver self-efficacy also increased, and both patients and caregivers reported satisfaction with the format.³³ Telehealth is not a perfect replacement for in-person care, particularly for patients who need regular medical monitoring, but it meaningfully expands the pool of people who can access evidence-based treatment.

The treatment of ARFID (avoidant/restrictive food intake disorder), a newer diagnostic category, is also emerging through virtual delivery. A large naturalistic study found that both youth and adults improved on measures of food variety, weight, anxiety, and depression over the course of treatment. Youth patients on weight restoration started at about 85% of their target weight and reached 94% by week 35.³⁴

The Toll on Caregivers

The statistics on treatment outcomes usually focus on patients, but the experience of eating disorders radiates outward. A New Zealand study found that caregivers reported a median 14% reduction in income during a year of caregiving, with individual losses ranging from a few hundred dollars to over $140,000. More than 90% reported impaired work productivity, and over a third had to take extended leave of more than four weeks.³⁵

The psychological cost is just as stark. Current caregivers reported higher levels of depression and stress than those no longer actively caregiving. Perhaps the most telling finding: among caregivers whose loved ones were already in recovery, more than 25% still experienced ongoing post-traumatic symptoms related to their caregiving experience.³⁶ The illness can leave lasting psychological marks on families even after the person with the eating disorder has improved. Treatment programs that include caregiver support are not a luxury but a clinical necessity, because caregiver wellbeing affects the family environment that shapes recovery.
