Eating Disorder Statistics and Facts

Eating disorders are easy to underestimate. They are often hidden, frequently misunderstood, and surrounded by stereotypes that keep people from recognizing them, in themselves or in someone they love. The data tells a different story than the stereotypes do: these conditions are common, serious, and far more connected to substance use than most people realize.

This guide pulls together the most reliable statistics on eating disorders, what they mean, and why they matter for getting the right help. Every figure here is drawn from authoritative sources such as the National Institute of Mental Health, peer-reviewed research, and national eating disorder organizations.

How common are eating disorders?

Eating disorders are far more widespread than many people assume. An estimated 9 percent of the U.S. population, about 28.8 million Americans, will have an eating disorder at some point in their lives, according to a Deloitte Access Economics report produced with Harvard's STRIPED program.

Looking at specific diagnoses among U.S. adults, the National Institute of Mental Health reports these lifetime prevalence figures:

• Binge-eating disorder: 2.8 percent (the most common eating disorder)
• Bulimia nervosa: 1.0 percent
• Anorexia nervosa: 0.6 percent

Among adolescents ages 13 to 18, an estimated 2.7 percent have had an eating disorder, and the rate is more than twice as high in girls (3.8 percent) as in boys (1.5 percent).

Who develops an eating disorder?

One of the most damaging myths is that eating disorders only affect young, thin, affluent women. In reality they affect people of every gender, age, body size, race, and income level. While the NIMH data show higher prevalence among women and girls, men and boys make up a meaningful share of cases, and they are often underdiagnosed because the stereotype works against them.

Body size is not a reliable signal either. Most people with eating disorders are not medically underweight, and people in larger bodies are among those at highest risk. The takeaway: you cannot tell whether someone has an eating disorder by looking at them.

How serious are eating disorders?

Eating disorders are among the deadliest mental illnesses. The 2020 STRIPED and Deloitte report estimated that eating disorders are linked to roughly 10,200 deaths each year in the United States, which works out to about one death every 52 minutes.

Anorexia nervosa is especially dangerous. A widely cited meta-analysis in the Archives of General Psychiatry found that people with anorexia nervosa have a mortality rate markedly higher than expected for their age, driven by both medical complications and suicide. The crucial point behind these numbers is that most eating-disorder deaths are preventable. Early, sustained treatment changes the trajectory.

The hidden costs

The same STRIPED and Deloitte analysis put the total economic cost of eating disorders in the U.S. at $64.7 billion in a single year, with the largest share coming from lost productivity. That figure does not capture the harder-to-measure toll on relationships, education, careers, and quality of life, which the report valued separately in the hundreds of billions.

How do eating disorders and substance use overlap?

For an addiction treatment center, this is the most important set of statistics. Eating disorders and substance use disorders co-occur at strikingly high rates.

According to the National Eating Disorders Association:

• Up to 50 percent of people with an eating disorder also misuse alcohol or other drugs, about five times the rate in the general population.
• Up to 35 percent of people who misuse or are dependent on alcohol or other drugs also have an eating disorder, roughly 11 times the general-population rate.

These conditions share many of the same drivers: trauma, anxiety, depression, difficulty regulating emotions, and the use of a behavior (restricting, purging, drinking, or using) to numb or control distress. Because they reinforce each other, treating one while ignoring the other often leaves a person vulnerable to relapse.

That is why integrated care matters. When someone enters treatment for a substance use disorder, screening for a co-occurring eating disorder, and addressing both together, gives the strongest foundation for lasting recovery. Our mental health treatment and evidence-based therapies are built to address the conditions underneath the behavior, not just the behavior itself.

What do these numbers mean for treatment?

Statistics describe a population, but recovery happens one person at a time. A few practical conclusions follow from the data:

• Early treatment improves outcomes. Eating disorders tend to become more entrenched the longer they go untreated, so recognizing the signs and acting matters.
• Co-occurring conditions are the rule, not the exception. Eating disorders frequently travel with substance use, anxiety, depression, and mood disorders, and an effective plan accounts for all of them.
• Evidence-based therapy is central. Approaches such as cognitive behavioral therapy and dialectical behavior therapy help people understand the thoughts and emotions driving harmful behaviors and build healthier coping skills.
• Aftercare protects recovery. Because relapse risk is highest after a structured program ends, ongoing aftercare and support are essential to staying well.

If you are worried about your own eating or substance use, or about someone close to you, you do not need a diagnosis or a "bad enough" reason to reach out. A confidential conversation is a reasonable first step.

When to reach out for help

Consider talking to a professional if you or someone you care about is preoccupied with food, weight, or body image to the point that it interferes with daily life, is using food restriction, bingeing, or purging to cope, or is combining disordered eating with alcohol or drug use. You can also start by learning about our team and the clinicians who would be part of your care.

Eating disorders and substance use disorders are both treatable. The statistics are sobering, but they describe a problem with a solution. With the right, evidence-based support, recovery is realistic, and it starts with a single conversation.
