Eating Disorders: Types, Prevalence, Misunderstandings, and Treatment

Eating disorders remain among the gravest mental health conditions—but they are diverse, widespread, and treatable. Understanding the various forms, dispelling myths, and improving access to care are vital for saving lives and fostering recovery.

1. Introduction & Common Misunderstandings

Eating disorders are serious mental illnesses marked by persistent, unhealthy eating behaviors and distorted attitudes toward food, weight, or body image. They can severely affect physical health, emotional wellbeing, and social functioning (Psychiatry.org, Health).

A major source of confusion is that many people believe eating disorders only affect young women who are underweight. In reality, they affect all genders, ages, body types, and backgrounds—and can manifest in diverse forms (Health, Glamour).


2. Types of Eating Disorders

According to DSM-5 and other clinical sources, eating disorders include the following:

  • Anorexia nervosa (AN) – Deliberate restriction of food intake due to fear of gaining weight or distorted body image (Psychiatry.org, nhs.uk).
  • Bulimia nervosa (BN) – Recurrent episodes of binge eating followed by compensatory behaviors such as vomiting, laxative use, or excessive exercise (Psychiatry.org, nhs.uk).
  • Binge-Eating Disorder (BED) – Repeated episodes of uncontrolled overeating without purging; most common eating disorder in adults (Psychiatry.org, ADAA, Glamour).
  • Avoidant/Restrictive Food Intake Disorder (ARFID) – Restrictive eating due to sensory issues, lack of interest, or fear of consequences, without weight/body image concerns (Psychiatry.org, nhs.uk).
  • Other Specified Feeding or Eating Disorders (OSFED) – When symptoms don’t align fully with other diagnoses; includes atypical anorexia, purging disorder, night eating syndrome, etc. (ADAA, nhs.uk, Within Health, derbyshirehealthcareft.nhs.uk).
  • Unspecified Feeding or Eating Disorder (UFED) – Used when there’s disordered eating but insufficient data to assign a specific diagnosis (Within Health).
  • Pica and Rumination Disorder – Rare conditions involving ingestion of non-food substances (pica) or regurgitating and re-chewing food (rumination) (Psychiatry.org, nedc.com.au).
  • Orthorexia – Not an official diagnosis; excessive obsession with healthy or clean eating leading to malnutrition and social isolation (TIME).

3. Prevalence & Statistics


4. Co-morbidity & Who is Affected

  • Mental health overlap: AN often co-occurs with anxiety (~48%) and mood disorders (~42%); BN and BED show even higher co-occurrence (e.g., ~95% of BN) (National Institute of Mental Health).
  • Underdiagnosis & diversity: Men, BIPOC, LGBTQ+ individuals, and older adults often go underdiagnosed due to stigma and misconceptions (Alsana®, Verywell Health, Glamour).
  • At-risk groups: High prevalence among athletes, dancers, medical professionals, and those in appearance-conscious fields (Verywell Health).
  • Triggers: Genetics, perfectionism, trauma, societal pressure, and social media influence increase vulnerability (Verywell Health, Alsana®, TIME).

5. Treatment & Recovery

  • Evidence-based therapies:
    • Cognitive Behavioral Therapy (CBT) is considered highly effective for various eating disorders, focusing on reshaping harmful thoughts and behaviors around food and body image (Wikipedia).
    • Multidisciplinary care—including therapy, nutritional counseling, and medical monitoring—is essential (Psychiatry.org, Health).
  • Treatment coverage:
    • About 34% of those with AN, 43% with BN, and 44% with BED sought treatment for their disorder; many more received help for related emotional issues (National Institute of Mental Health).
    • Overall, treatment access remains limited: fewer than one-third of affected women receive care by their 40s or 50s (ANAD).
  • Early intervention matters: Starting treatment early improves survival and recovery rates significantly (Verywell Health, Health).
  • Barriers: Legal and system issues—such as in the case of Carly Kempf (see news story)—show how lack of continuity, access, and awareness can limit effective care (Times Union).

6. Conclusion

Eating disorders remain among the gravest mental health conditions—but they are diverse, widespread, and treatable. Understanding the various forms, dispelling myths, and improving access to care are vital for saving lives and fostering recovery.
