- 25% of people with anorexia nervosa do not achieve full recovery
- DSM-5-TR criteria for anorexia nervosa require an individual to have significantly low body weight for context and age
- Dysregulation of serotonin signaling is implicated by evidence from multiple studies in eating disorders, including altered 5-HT transporter availability in neuroimaging
- In the U.S., only about 22% of adults with any mental illness receive treatment in a given year (NHIS, 2022)
- NICE recommends fluoxetine for bulimia nervosa, with evidence of symptom reduction versus placebo in randomized controlled trials

- $114.0 million global market size for eating-disorder-specific digital health and telehealth solutions in 2023
- A $6.0 billion annual global market for mental health apps was estimated for 2023 (spanning disorder categories including eating disorders)

- In a systematic review, 9% of studies reported significant adverse outcomes for body dissatisfaction linked to thin-ideal content exposure

02
19.0% of individuals with eating disorders have a depressive disorder comorbidity
03
38.7% of U.S. adults with binge eating disorder had at least one comorbid psychiatric disorder
04
In 2019, eating disorders caused an estimated 3.1 million years lived with disability (YLDs) in the U.S.
05
Anorexia nervosa has one of the highest mortality risks among psychiatric disorders, with reported standardized mortality ratios around 5
06
Between 1970 and 2014, the overall case fatality proportion reported across studies for anorexia nervosa was about 5%
Interpretation
Prevalence & Burden Interpretation
Even though only 4.4% of the global population will meet criteria for an eating disorder over their lifetime, the burden is substantial in the Prevalence and Burden category because U.S. estimates show 3.1 million YLDs in 2019 and anorexia nervosa carries a markedly high mortality risk with standardized mortality ratios around 5 and an overall case fatality proportion near 5% across studies.

03
Dysregulation of serotonin signaling is implicated by evidence from multiple studies in eating disorders, including altered 5-HT transporter availability in neuroimaging
04
Higher rates of self-harm are reported in eating disorders, with one meta-analysis estimating about 27% lifetime prevalence of self-harm among people with eating disorders
05
About 30% of people with binge-eating disorder have obesity (BMI ≥30) in clinical samples
06
In a systematic review, 34% of individuals with anorexia nervosa reported amenorrhea or menstrual dysfunction at presentation
07
In clinical practice, weight restoration targets for anorexia nervosa commonly aim for at least 90% of expected body weight
Interpretation
Clinical Presentation Interpretation
Clinically, eating disorders show a consistent pattern of significant impairment at presentation, with 34% of people with anorexia nervosa reporting amenorrhea or menstrual dysfunction and about 27% lifetime prevalence of self-harm, while only 25% of anorexia nervosa cases fail to fully recover.

03
In pivotal randomized trials, cognitive behavioral therapy (CBT) reduced binge-eating episodes by about 50% from baseline
04
In an RCT of CBT-Enhanced for binge-eating disorder, 1-year follow-up showed around 37% remission from binge-eating disorder
05
In a U.S. survey, 59% of respondents with eating disorders reported they delayed seeking treatment
06
Family-based treatment (FBT) for adolescent anorexia nervosa shows remission rates around 40–50% in clinical trials
07
For treatment of adolescent anorexia nervosa, FBT outperforms individual psychodynamic therapy in randomized trials with significantly higher weight gain
Interpretation
Treatment Access Interpretation
Despite effective treatments being available, only about 22% of U.S. adults with mental illness get treatment each year and 59% of people with eating disorders delay seeking help, which likely contributes to outcomes like remission rates of only around 37% after CBT-enhanced and about 40 to 50% with family-based treatment rather than reflecting broad access to care.

03
Annual costs of eating disorder illness in the U.S. have been estimated at $64.7 billion (2017 dollars)
04
$12,000+ per patient episode is a common order-of-magnitude for inpatient costs for eating disorders in commercial claims datasets
05
In an analysis of U.S. inpatient data, mean length of stay for anorexia nervosa was about 14 days
06
In insurer analyses, specialty outpatient programs for eating disorders cost several times more per visit than general outpatient mental health ($300–$800 range reported)
Interpretation
Industry Economics Interpretation
For the industry economics of eating disorders, the scale of spending is striking, with $64.7 billion in annual U.S. illness costs and inpatient stays commonly costing $12,000 or more per episode and averaging about 14 days for anorexia nervosa, even as the market for eating-disorder-specific digital health and telehealth solutions is only $114.0 million in 2023.

Interpretation
Industry Trends Interpretation
Industry Trends data suggest that digital pathways are reaching meaningful portions of vulnerable populations, with 8.4% of online participants screening positive for eating disorder risk and therapy and interventions showing medium to strong symptom reductions, while thin ideal content is still linked to significant body dissatisfaction in 9% of studies.

4.0% of the U.S. adult population reported past-year symptoms consistent with an eating disorder in the NCS-R past-year interview analysis

Bulimia nervosa has a typical onset range that most commonly begins in late adolescence or early adulthood, with most cases starting between ages 15–24 (age-of-onset distribution reported in clinical review literature)
03
U.S. inpatient hospitalizations for eating disorders were 33.4 per 100,000 population (rate of hospitalizations across years reported in the analyzed national inpatient dataset)
Interpretation
Epidemiology Interpretation
From an epidemiology standpoint, eating disorders affect about 4.0% of U.S. adults each year, and with bulimia often beginning in late adolescence or early adulthood alongside 33.4 inpatient hospitalizations per 100,000 people, the pattern points to both a meaningful population burden and an important life stage for early onset.
