Anorexia vs Bulimia in Teens: Recognizing the Differences
Anorexia nervosa and bulimia nervosa are two distinct eating disorders that are frequently confused because they share some overlapping features — particularly a preoccupation with body weight and shape. According to the National Eating Disorders Association (NEDA), eating disorders affect approximately 2.7% of adolescents, with anorexia and bulimia being among the most common and most medically dangerous.
At Silver State, our clinical team treats both anorexia and bulimia in adolescents ages 11–17 using evidence-based approaches that address the psychological, behavioral, and nutritional components of each disorder. Understanding the key differences is important for families who suspect their teen may be struggling.
Overview
Anorexia Nervosa
Anorexia nervosa is characterized by severe restriction of food intake leading to significantly low body weight, an intense fear of gaining weight, and a distorted body image. According to the National Institute of Mental Health (NIMH), anorexia has the highest mortality rate of any mental health disorder. In adolescents, anorexia can severely impair physical development, bone health, and cardiovascular function during critical growth years.
Best for:
Teens who are significantly restricting food intake, losing weight rapidly, expressing intense fear of weight gain, or showing signs of malnutrition.
Key Features:
- Severe restriction of caloric intake
- Significantly low body weight for age and height
- Intense fear of gaining weight or becoming fat
- Distorted body image — seeing themselves as overweight despite being underweight
- Medical complications: bone loss, cardiac issues, amenorrhea
Bulimia Nervosa
Bulimia nervosa involves recurrent episodes of binge eating followed by compensatory behaviors such as self-induced vomiting, excessive exercise, or laxative misuse. According to the American Psychiatric Association (APA), bulimia is characterized by a cycle of bingeing and purging that occurs at least once a week for three months. Unlike anorexia, teens with bulimia may maintain a normal or above-normal body weight, making the disorder harder for families to detect.
Best for:
Teens engaging in binge-purge cycles, those who eat large amounts in short periods and then compensate through vomiting, over-exercising, or other purging methods.
Key Features:
- Recurrent episodes of binge eating (large amounts in short periods)
- Compensatory behaviors: purging, excessive exercise, fasting, laxatives
- Body weight may appear normal or above normal
- Shame and secrecy around eating behaviors
- Medical complications: dental erosion, esophageal damage, electrolyte imbalances
Key Differences
Which Is Right for Your Teen?
Both anorexia and bulimia are serious medical and psychological conditions that require professional treatment. According to the National Eating Disorders Association, early intervention dramatically improves outcomes for both disorders. Some teens develop features of both — for example, restricting food most of the time but occasionally binging and purging.
At Silver State, our eating disorder treatment addresses both the disordered eating behaviors and the underlying psychological factors driving them. Treatment includes individual therapy (primarily CBT-E, enhanced cognitive behavioral therapy for eating disorders), nutritional counseling, family therapy, and medical monitoring. The clinical approach is tailored to the specific eating disorder diagnosis.
