This fear is often manifested by depriving the body of food. By updating diagnostic criteria, changes to the DSM-5, which is published by the American Psychiatric Association, should help people suffering from eating disorders receive appropriate treatment and, hopefully, also obtain insurance coverage. The DSM-5 outlines specific criteria for anorexia nervosa, which include persistent restriction of energy intake, intense fear of gaining weight, and disturbance in self-perceived weight or shape.

The new DSM-5 introduces important and long-awaited changes in the criteria used in the diagnosis of eating disorders.
According to the DSM-5, the category of another specific eating or eating disorder (OSFED) applies to people who experience significant distress due to symptoms that are similar to those of disorders such as anorexia, bulimia and binge eating disorder, but who do not meet the full criteria as outlined in the DSM-5 for diagnosis of one of these disorders. The DSM-5 removed the category known as Eating Disorder Not Otherwise Specified (EDNOS) and introduced Binge Eating Disorder (BED) as a separate diagnosis for the first time. Even if all of the DSM-5 criteria for anorexia are not met, a serious eating disturbance or eating disorder can still occur. The DSM-5 also recognizes Rumination Disorder as a diagnosable eating disorder, further expanding the clinical understanding of these mental health conditions.
Anorexia is classified as a mental health disorder in the DSM-5, and healthcare professionals use these diagnostic criteria to identify and communicate a patient's mental health condition.
Introduction to Eating Disorders
Eating disorders are complex mental health disorders that profoundly affect both the mind and body. Among the most recognized are anorexia nervosa and bulimia nervosa, each marked by a persistent eating disturbance and a range of disorder symptoms that can severely compromise physical health. Individuals struggling with eating disorders may experience significantly low body weight, recurrent episodes of binge eating, or an intense fear of gaining weight or becoming fat—even when their body weight is already below what is considered healthy.
The Diagnostic and Statistical Manual (DSM), published by the American Psychiatric Association, serves as the gold standard for diagnosing mental disorders, including eating disorders. According to the DSM, anorexia nervosa is characterized by a persistent restriction of energy intake relative to one’s body weight, leading to significantly low body weight. This restriction is often accompanied by a distorted body image, excessive exercise, and a relentless fear of gaining weight. Bulimia nervosa, another serious eating disorder, involves cycles of binge eating followed by compensatory behaviors to prevent weight gain.
Eating disorder symptoms can vary widely, but commonly include a preoccupation with body image, low body weight, and unhealthy eating habits. These mental health conditions can lead to a host of medical complications if left untreated. Early identification and intervention are crucial, as prompt treatment can help prevent the long-term physical and psychological consequences associated with eating disorders. By understanding the criteria outlined in the DSM and recognizing the warning signs, clinicians and loved ones can better support individuals on the path to recovery.

Diagnostic Criteria for significantly low body weight
The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) revolutionizes the precision of eating disorder identification through innovative, evidence-based criteria that streamline diagnosis for anorexia nervosa, bulimia nervosa, and binge eating disorder. For anorexia nervosa, the DSM-5 establishes cutting-edge parameters centered on significantly low body weight—strategically defined as a body mass index (BMI) below 17 kg/m² for adults, or below the 5th percentile for children and adolescents. This comprehensive framework identifies low body weight resulting from persistent energy intake restriction relative to physical health requirements, often driven by an intense fear of weight gain or becoming fat, even when significantly underweight.
A transformative hallmark of anorexia nervosa involves distorted body image perception, where individuals may not recognize the seriousness of their current low body weight status. There exists an undue influence of body weight or shape on self-evaluation, coupled with a persistent lack of recognition regarding the medical risks associated with being underweight. The DSM-5 strategically specifies that these eating disorder manifestations must not occur exclusively during binge eating disorder episodes, nor be better explained by alternative mental health disorders such as bulimia nervosa.
Diagnosis involves a comprehensive, streamlined evaluation by a qualified treatment partnership. If a doctor suspects anorexia, they will run several exams and tests to help narrow down a diagnosis. This innovative approach typically encompasses a physical examination, which may include measuring height and weight, checking vital signs such as blood pressure, and examining the abdomen. A complete blood count is performed, and lab tests may also include tests to check electrolytes and protein levels. X-rays may be taken to measure bone density or check for stress fractures or broken bones in individuals suspected of having anorexia. Electrocardiograms may be used to identify heart irregularities in patients with anorexia. Additional laboratory assessments are used to systematically rule out medical causes of weight loss or related symptoms. A mental health evaluation proves essential for identifying co-occurring conditions like anxiety disorders or depression, as well as assessing other symptoms that may help differentiate anorexia from other conditions, which can significantly influence the developmental trajectory of the eating disorder.
The severity classification of anorexia nervosa leverages World Health Organization categories for thinness in adults, strategically based on BMI, and corresponding percentiles for children and adolescents. This evidence-based framework enables treatment partnerships to develop customized, comprehensive treatment programs that address both physical health and psychological requirements of the individual, supporting healthy weight restoration and enhanced body image perception. Common psychotherapy approaches for treating anorexia nervosa include Cognitive Behavioral Therapy (CBT) and Family-Based Treatment (FBT).
In addition to anorexia nervosa, the DSM-5 establishes innovative criteria for additional eating disorders. Bulimia nervosa is characterized by recurrent binge eating episodes, followed by compensatory behaviors such as self-induced vomiting, laxative misuse, or excessive exercise. Binge eating disorder involves recurrent binge eating episodes without these compensatory behaviors, representing a streamlined diagnostic category.
It’s critical to recognize that atypical anorexia nervosa can manifest when all anorexia nervosa criteria are met except for significantly low body weight. Individuals with atypical anorexia nervosa may still experience severe eating disorder symptoms and require prompt, innovative treatment interventions.
Early identification and intervention prove revolutionary in preventing eating disorder progression. Cutting-edge screening tools, such as the SCOFF questionnaire, can effectively identify at-risk individuals. The SCOFF questionnaire is an example of a screening tool used for early detection. A comprehensive treatment program should involve a multidisciplinary partnership—including psychologists, psychiatrists, and registered dietitians—to strategically address both physical and psychological aspects of the disorder. With the right support partnership and evidence-based treatment approaches, individuals struggling with eating disorders can achieve measurable recovery outcomes, enhanced physical health, and a transformed relationship with their body weight and body image.
