Bulimia Nervosa: As Classified by the DSM-5

Bulimia Nervosa, as described in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), is a serious eating disorder characterized by a cycle of binge eating followed by compensatory behaviors to prevent weight gain. Individuals with Bulimia Nervosa often feel a lack of control over their eating during binge episodes and engage in behaviors such as self-induced vomiting, misuse of laxatives, fasting, or excessive exercise to compensate.

Features and Symptoms of Bulimia Nervosa

  • Binge Eating: Consuming a considerable amount of food in a discrete period (e.g., within any 2 hours), accompanied by a sense of loss of control over eating during the episode.
  • Compensatory Behaviors: Recurrent inappropriate compensatory behaviors to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, or other medications; fasting; or excessive exercise.
    Frequency: The binge eating and inappropriate compensatory behaviors both occur, on average, at least once a week for three months.
  • Self-Evaluation: Self-esteem is overly influenced by body shape and weight.
  • Not Exclusively During Episodes of Anorexia Nervosa: The behavior does not occur exclusively during episodes of Anorexia Nervosa.
Bulimia Nervosa is a serious eating disorder characterized by a cycle of binge eating followed by compensatory behaviors to prevent weight gain.

Distinguishing Features: The Difference Between Bulimia Nervosa & Other Eating Disorders

Compared to Binge-Eating Disorder:

  • Both disorders involve episodes of binge eating, but subsequent inappropriate compensatory behaviors characterize Bulimia Nervosa to prevent weight gain, which is not present in Binge-Eating Disorder.

Compared to Anorexia Nervosa:

  • While both may involve binge eating and purging behaviors, individuals with Anorexia Nervosa have a significantly lower body weight. Bulimia Nervosa usually presents in individuals who are average weight or overweight and focuses more on cyclical binge-purge behavior rather than severe restriction and low body weight.

Compared to Avoidant/Restrictive Food Intake Disorder (ARFID):

  • ARFID involves avoiding or restricting food intake but does not involve binge eating or compensatory behaviors. It’s driven by a lack of interest in eating or food, sensory characteristics of food, or concern about aversive consequences, without the distress about body shape and weight seen in Bulimia Nervosa.

Health Consequences and Treatment

The cycle of binging and purging in Bulimia Nervosa can lead to serious health consequences, including electrolyte imbalances, gastrointestinal problems, dental issues, and heart complications. Psychological comorbidities, such as anxiety and depression, are also com

Fact Versus Fiction: The Truth About Bulimia Nervosa

Bulimia Nervosa is often shrouded in misconceptions that can hinder understanding, support, and treatment for those affected. Dispelling these myths with facts and research is crucial for fostering a more informed and empathetic approach to this severe eating disorder.

MYTH 1: Bulimia Nervosa is a choice or about vanity.

Truth: Bulimia Nervosa is a complex mental health disorder that involves biological, psychological, and sociocultural factors. It’s not a lifestyle choice or merely about wanting to look a certain way. Research emphasizes that genetic predispositions and brain chemistry play significant roles in its development.

MYTH 2: You can tell someone has Bulimia Nervosa by looking at them.

Truth: Individuals with Bulimia Nervosa can be of normal weight, underweight, or overweight. The disorder’s hallmark is not how someone looks but rather their pattern of binge eating followed by compensatory behaviors.

MYTH 3: Bulimia Nervosa only affects young, white females.

Truth: While it’s true that Bulimia Nervosa is more commonly diagnosed in females and often begins in the teenage years or young adulthood, it can affect individuals of any gender, age, race, or socioeconomic status. Men and people of color also suffer from Bulimia Nervosa, though they may be less likely to seek treatment due to societal stigma.

MYTH 4: Purging eliminates all the calories consumed during a binge.

Truth: This is a dangerous misconception. Purging, whether through vomiting or the use of laxatives, does not eliminate all the calories consumed during a binge. Furthermore, these behaviors can cause serious physical health issues, including electrolyte imbalances, gastrointestinal damage, and dental problems.

MYTH 5: Bulimia Nervosa is less severe than Anorexia Nervosa.

Truth: Bulimia Nervosa is a serious and potentially life-threatening condition that can lead to severe physical complications, such as heart problems, kidney damage, and gastrointestinal issues, as well as significant psychological distress. It is as serious as any other eating disorder and requires appropriate treatment.

MYTH 6: Recovery from Bulimia Nervosa is simply a matter of self-control.

Truth: Recovery from Bulimia Nervosa involves much more than willpower. Effective treatment typically includes therapy, such as cognitive-behavioral therapy (CBT), nutritional counseling, and sometimes medication. Support from professionals, family, and peers is crucial for recovery.

Understanding Bulimia Nervosa through accurate information and research is essential for debunking harmful myths, reducing stigma, and supporting those who are struggling with this disorder. It’s important to approach those affected with empathy and to encourage professional treatment and support for recovery.

Bulimia Nervosa and Addiction: Further Complications

Substance abuse is notably higher among individuals with Bulimia Nervosa compared to the general population. Research has consistently shown a significant link between Bulimia Nervosa and increased rates of substance abuse, including the misuse of alcohol, stimulants, and other substances.

Rates of Substance Abuse in Bulimia Nervosa:

  • General Findings: Studies suggest that between 30% to 50% of individuals with Bulimia Nervosa engage in substance abuse at some point in their lives. This rate is significantly higher than that observed in the general population.
  • Alcohol Abuse: Alcohol is one of the most commonly abused substances among those with Bulimia Nervosa. The rates of alcohol abuse and binge drinking in individuals with this eating disorder are considerably higher than in those without eating disorders.
  • Stimulant Abuse: The abuse of stimulants, including cocaine and amphetamines, is also prevalent among individuals with Bulimia Nervosa. These substances may suppress appetite, control weight, or enhance mood.
  • Laxatives and Diuretics Misuse: While not always classified under traditional substance abuse categories, the misuse of laxatives and diuretics is common in Bulimia Nervosa as part of compensatory behaviors to control weight.

Factors Contributing to High Rates of Substance Abuse:


Coping Mechanism: Substance abuse may serve as a maladaptive coping mechanism to manage negative emotions, stress, or the psychological distress associated with Bulimia Nervosa.

  • Impulsivity: Characteristics of impulsivity and risk-taking behavior, which are more common in individuals with Bulimia Nervosa, may contribute to a higher propensity for substance abuse.
  • Comorbid Psychiatric Disorders: The high co-occurrence of other psychiatric disorders, such as anxiety and depression, with Bulimia Nervosa, may also increase the likelihood of substance abuse as individuals seek to self-medicate.

The intersection between Bulimia Nervosa and substance abuse highlights the need for comprehensive treatment approaches that address both the eating disorder and the substance use issues. Identifying and treating co-occurring substance abuse is critical for achieving recovery and improving overall health outcomes for individuals with Bulimia Nervosa.

Recognizing the Signs: When to Seek Help for Bulimia Nervosa

Recurrent Episodes of Binge Eating

Consuming large amounts of food quickly while lacking control over eating behaviors.

Compensatory Behaviors

Engaging in behaviors to prevent weight gain after binge eating, such as self-induced vomiting, excessive exercise, misuse of laxatives, diuretics, or fasting.

Preoccupation with Body Image and Weight

An undue emphasis on body shape and weight in self-evaluation or persistent behavior that interferes with weight gain despite being at an average weight.

Emotional Distress Related to Eating Habits

Feelings of guilt, shame, or distress about eating habits or body image.

Physical Symptoms

Signs of malnutrition, dehydration, electrolyte imbalances, dental issues (from vomiting), or gastrointestinal problems.

Impact on Daily Life

When eating habits, thoughts about food, weight, or body image significantly interfere with daily activities, relationships, work, or school performance.

If you or someone you care about shows any of these signs, it’s essential to reach out to a healthcare provider, such as a primary care physician, psychiatrist, or a specialist in eating disorders. Healthcare professionals can provide a comprehensive assessment, diagnose, and discuss appropriate treatment options, including nutritional counseling, therapy, and sometimes medication. Remember, seeking help is a sign of strength, and professional support is a critical step toward recovery.
