Eating disorders are among the most dangerous mental health conditions for teens — anorexia has the highest mortality rate of any mental illness. They are also among the most treatable when caught early and treated with evidence-based approaches. The wrong treatment can make them worse. VERIFY SOURCE — anorexia mortality statistics
Understanding eating disorders
Eating disorders are not about food. They are about emotional regulation, control, identity, anxiety, and trauma — expressed through food and body. This matters because treatment that addresses only the eating behavior, without addressing the underlying drivers, doesn't last.
Eating disorders affect teens of all body sizes, all genders, all races, all socioeconomic backgrounds. The cultural image of eating disorders as a thin white girl's illness is wildly inaccurate and contributes to under-diagnosis in everyone else. REVIEW — clinical reviewer to verify framing
Types and presentations
- Anorexia Nervosa. Restriction of intake, intense fear of weight gain, distorted body image. Subtypes include restricting and binge-purge.
- Bulimia Nervosa. Episodes of binge eating followed by compensatory behaviors (purging, restricting, exercise).
- Binge Eating Disorder. Recurrent binge eating without compensatory behavior.
- ARFID (Avoidant Restrictive Food Intake Disorder). Restriction not driven by body image — sensory issues, fear of choking, lack of interest in food.
- OSFED (Other Specified Feeding or Eating Disorder). Significant disordered eating not meeting full criteria for above. Most clinically-presenting eating disorders fall here.
- Atypical Anorexia. Anorexia presentation in larger-bodied teens. Often missed.
How to recognize an eating disorder
Warning signs REVIEW — clinical verification needed:
- Significant weight loss or weight changes
- Skipping meals, eating in secret, disappearing after meals
- New rules around food (cutting out food groups, food rituals)
- Excessive exercise
- Body checking, mirror avoidance, weight obsession
- Withdrawal from social eating
- Use of laxatives, diet pills, vomiting
- Pre-occupation with food, recipes, calories
- Lanugo (fine body hair), cold intolerance, fainting
- Menstrual changes
Evidence-based treatment
For adolescent eating disorders, the strongest evidence supports: REVIEW — clinical verification needed
- Family-Based Treatment (FBT, "Maudsley"). Gold standard for adolescent anorexia and bulimia. Empowers parents to refeed their teen.
- Enhanced CBT (CBT-E). Strong evidence for bulimia and binge eating in older adolescents.
- Adolescent-Focused Therapy. Alternative to FBT for some presentations.
- Family-Based Treatment for ARFID. Adapted FBT.
Family-Based Treatment (Maudsley)
FBT is the most-evidence-based treatment for adolescent anorexia. It works on three principles: parents are not the cause of the eating disorder, parents are essential to the solution, and refeeding (restoring weight) is the foundation that other work builds on.
FBT has three phases:
- Phase 1: Refeeding. Parents take complete control of meals and weight restoration.
- Phase 2: Returning control. Gradual return of age-appropriate eating autonomy.
- Phase 3: Adolescent identity work. The non-eating-disorder developmental tasks of adolescence.
FBT is harder than it sounds, but the evidence is strong. Programs treating adolescent anorexia without FBT are working against the evidence base.
Medical risk and stabilization
Eating disorders carry serious medical risks. Cardiac complications, electrolyte imbalances, bone density loss, gastrointestinal damage. Medical clearance and ongoing medical monitoring are essential.
Some teens require medical hospitalization before mental health treatment can begin meaningfully. The Society for Adolescent Health and Medicine criteria for medical hospitalization in eating disorders provide a useful framework. VERIFY SOURCE — SAHM criteria current edition
When specialty treatment is needed
Most adolescent eating disorders can be treated in outpatient FBT. Higher levels of care are warranted when:
- Outpatient treatment isn't producing weight restoration
- Medical instability requires monitoring
- The teen cannot be safely managed in family-based outpatient care
- Severe co-occurring conditions complicate treatment
Eating disorder specialty programs are dramatically better than generalist programs for these cases. The infrastructure for medical monitoring, nutritional rehabilitation, and evidence-based treatment requires specialization.
Common questions, answered.
Can boys have eating disorders?
Yes. Approximately one in three eating disorders affects boys/men. They're under-diagnosed because of the cultural assumption that eating disorders are a female condition. VERIFY
What if my teen is in a larger body and restricting?
This is atypical anorexia and is just as serious as anorexia in a thin body. Often missed by pediatricians who see the weight loss as positive. Get specialty assessment.
Should we discuss food and weight with our teen?
Generally, follow the lead of your treating clinician. Body talk and weight talk often fuel eating disorder thoughts. Focus on functioning and feelings, not on bodies and food.
