Understanding and Managing Anorexia in Adolescents

Introduction to Anorexia Management

The American Academy of Pediatrics recommends that parents understand they are not to blame for their child's anorexia nervosa, but are vital to therapeutic success and responsible for weight restoration 1, 2
Parents must learn to separate their child from the illness, as the eating disorder is not their child's identity, and treatment requires a nonauthoritarian approach where parents take control of refeeding without blame or punishment 1, 2

Mortality rates for eating disorders are among the highest for any psychiatric disorder, with cardiac complications responsible for at least one-third of all deaths 3, 4, 5
More than half of adolescents with eating disorders have normal laboratory results despite being medically unstable, indicating that normal tests do not mean safety 3, 5
Critical warning signs parents must monitor include bradycardia (heart rate <50 beats/minute during the day), hypotension (<90/45 mm Hg), hypothermia (body temperature <96°F), and orthostatic changes (pulse increase >20 beats/min or blood pressure drop >20 mm Hg systolic on standing) 1, 2, 6

The three-phase treatment framework involves parents taking full control of all eating decisions and meal planning in Phase 1, with a focus on medical stabilization and nutritional rehabilitation 1, 2
As weight restoration progresses, control gradually returns to the child or adolescent in Phase 2, after medical stability is achieved 1, 2
Phase 3 focuses on adolescent development, addressing broader issues and preparing for termination of formal treatment 1, 2

Parents must avoid all comments about body weight, as even well-intended comments can be perceived as hurtful, and instead focus on healthful eating behaviors 6, 2
Parental weight talk is linked to higher rates of overweight and eating disorders, and family weight teasing predicts development of overweight status, binge eating, and extreme weight-control behaviors 6, 1
Parents should expect their pediatrician to act as a consultant, explain the medical seriousness of the eating disorder, monitor and manage the medical status of the adolescent, empower parents in decision-making, and communicate regularly with the patient, family, and therapist 1, 2

Do not wait for laboratory abnormalities to take action, as most patients with eating disorders have normal test results despite serious illness 3, 5
Do not assume the child will "grow out of it", as early diagnosis and intervention are associated with improved outcomes 1, 6
Do not attempt to manage the eating disorder alone, as it requires a multidisciplinary health care team 1, 6
