Bulimia Nervosa

Bulimia nervosa is characterized by recurrent episodes of binge eating followed by compensatory behaviors to prevent weight gain. During binge episodes, individuals consume large amounts of food in a short period while feeling a loss of control. This is followed by purging through self-induced vomiting, laxative misuse, excessive exercise, or fasting.

Unlike anorexia nervosa, people with bulimia often maintain a relatively normal weight, making the disorder less visible but no less dangerous. The cycle of bingeing and purging can dominate a person's life, affecting their physical health, emotional well-being, and social relationships. Many people with bulimia experience intense shame about their behaviors and go to great lengths to hide them.

The disorder often develops during adolescence or early adulthood, frequently beginning with dieting behavior that spirals out of control. While bulimia can affect anyone, it's most common in young women. The good news is that with appropriate treatment, people can break free from the binge-purge cycle and develop a healthy relationship with food and their body.

Bulimia nervosa involves behavioral, physical, and emotional symptoms. Because people with bulimia often maintain normal weight and hide their behaviors, the disorder can go undetected for years.

Emotional and Mental Symptoms

• Preoccupation with body shape and weight
• Fear of gaining weight
• Distorted body image
• Low self-esteem tied to body image
• Feelings of shame and guilt after bingeing
• Depression and mood swings
• Anxiety, especially around meals
• Feeling out of control
• Social isolation
• Impulsivity in other areas of life
• Perfectionism
• Difficulty regulating emotions

The Binge-Purge Cycle

Understanding the cycle is crucial for recognizing bulimia:

1. Trigger: Stress, emotions, hunger from restricting
2. Binge: Eating large amounts rapidly, feeling out of control
3. Guilt/Shame: Intense negative feelings about the binge
4. Purge: Compensatory behavior to "undo" the binge
5. Temporary Relief: Brief emotional relief
6. Negative Feelings Return: Shame, guilt, low self-esteem
7. Restriction: Attempts to diet, leading to hunger
8. Cycle Repeats: Restriction triggers next binge

Purging Type

• Self-induced vomiting (most common)
• Misuse of laxatives
• Misuse of diuretics
• Misuse of enemas
• May use multiple purging methods

Non-Purging Type

• Excessive exercise
• Fasting or severe restriction
• Compensatory behaviors without purging
• May alternate between methods

Severity Levels

Based on frequency of compensatory behaviors per week:

• Mild: 1-3 episodes per week
• Moderate: 4-7 episodes per week
• Severe: 8-13 episodes per week
• Extreme: 14 or more episodes per week

Related Presentations

• Subclinical Bulimia: Some but not all criteria met
• Purging Disorder: Purging without binge eating
• Night Eating Syndrome: Binge eating at night
• Exercise Bulimia: Excessive exercise as primary compensation

Bulimia nervosa results from a complex interaction of genetic, biological, psychological, and sociocultural factors. No single cause explains the development of bulimia.

Biological Factors

• Genetics: 50-80% heritability rate
• Brain chemistry: Serotonin dysregulation affects mood and appetite
• Hormonal factors: Leptin and ghrelin imbalances
• Set point theory: Body's resistance to weight change
• Gut-brain axis: Digestive system influences

Psychological Factors

• Low self-esteem and self-worth
• Perfectionism and high achievement standards
• Impulsivity and difficulty with emotion regulation
• Body dissatisfaction and poor body image
• History of dieting or weight cycling
• Negative core beliefs about self
• Difficulty tolerating negative emotions
• All-or-nothing thinking patterns

Environmental and Social Factors

• Cultural ideals: Thin ideal and weight stigma
• Peer influences: Diet culture and body comparisons
• Family dynamics: Critical comments about weight/eating
• Trauma: Physical, emotional, or sexual abuse
• Life transitions: College, relationships, job changes
• Athletic/career pressure: Sports, modeling, performing arts
• Social media: Comparison and "fitspiration"
• Bullying: Especially weight-related teasing

Common Triggers

• Stressful life events
• Relationship problems
• Academic or work pressure
• Comments about weight or appearance
• Exposure to diet culture
• Comparison to others
• Negative emotions (loneliness, anger, boredom)
• Physical hunger from restriction

The repeated cycles of binging and purging can cause serious medical complications affecting nearly every organ system. Many complications can be reversed with recovery, but some may cause permanent damage.

Oral and Dental

• Delayed gastric emptying
• Laxative dependence
• Rectal prolapse
• Peptic ulcers

Cardiovascular

• Electrolyte imbalances (potassium, sodium, chloride)
• Irregular heart rhythms (arrhythmias)
• Low blood pressure
• Heart palpitations
• Potential heart failure

Diagnosing bulimia nervosa requires a comprehensive evaluation by healthcare professionals. Many people with bulimia hide their behaviors due to shame, making diagnosis challenging.

Diagnostic Criteria (DSM-5)

1. Recurrent episodes of binge eating characterized by:
   • Eating larger amounts than most people would in similar time
   • Sense of lack of control during episodes
2. Recurrent compensatory behaviors to prevent weight gain
3. Binge eating and compensatory behaviors occur at least once a week for 3 months
4. Self-evaluation unduly influenced by body shape and weight
5. Disturbance does not occur exclusively during anorexia nervosa episodes

Assessment Process

• Clinical interview: Detailed history of eating behaviors
• Physical examination: Check for physical signs
• Psychological assessment: Screen for co-occurring conditions
• Nutritional assessment: Evaluate eating patterns
• Medical tests: Blood work, ECG, other tests as needed

Laboratory Tests

• Complete blood count (CBC)
• Comprehensive metabolic panel
• Electrolyte levels (especially potassium)
• Thyroid function tests
• Amylase levels (may be elevated)
• Electrocardiogram (ECG)
• Dental examination
• Bone density scan if indicated

Differential Diagnosis

Conditions to rule out include:

• Anorexia nervosa (binge-eating/purging type)
• Binge eating disorder
• Other medical causes of vomiting
• Gastrointestinal disorders
• Major depressive disorder with appetite changes

Treatment for bulimia nervosa typically involves a combination of psychotherapy, nutritional counseling, and sometimes medication. Most people can be treated on an outpatient basis, though some may need higher levels of care.

Psychotherapy

Cognitive Behavioral Therapy (CBT)

• Gold standard treatment for bulimia
• Focuses on breaking the binge-purge cycle
• Challenges distorted thoughts about food and body
• Develops healthy coping strategies
• Typically 16-20 sessions
• 60-80% reduction in symptoms

Interpersonal Therapy (IPT)

• Focuses on relationship issues
• Addresses interpersonal triggers
• Improves communication skills
• Alternative when CBT unavailable
• Similar effectiveness to CBT

Dialectical Behavior Therapy (DBT)

• Helps with emotion regulation
• Teaches distress tolerance skills
• Useful for those with self-harm behaviors
• Combines individual and group therapy

Family-Based Treatment (FBT)

• Effective for adolescents
• Parents help interrupt behaviors
• Gradual return of control to teen
• Family education and support

Nutritional Counseling

• Normalize eating patterns

Other Medications

• Topiramate (anticonvulsant) - reduces binges
