Bulimia Nervosa

Bulimia Nervosa (BN) is a serious, potentially life-threatening eating disorder characterized by a cycle of binge eating followed by compensatory behaviors to prevent weight gain. Patients experience a loss of control during binge episodes, consuming large quantities of food, subsequently employing methods such as self-induced vomiting, laxative abuse, diuretic misuse, fasting, or excessive exercise.

BN arises from a complex interplay of biological, psychological, and environmental factors. Genetic predisposition (heritability estimated at 40-60%) interacts with environmental triggers, including childhood trauma, internalizing thin-ideal body standards, and early puberty. Neurobiological dysregulation of the serotonin system, which modulates satiety, is a primary suspected cause.

The pathophysiology involves a cycle of dietary restraint leading to metabolic and neurological disturbances. Frequent purging disrupts electrolyte homeostasis (hypokalemia, alkalosis). Repeated gastric acid exposure causes mucosal erosion of the esophagus and oral cavity. Chronic bingeing leads to gastric dilation, while chronic purging strains the cardiovascular system and renal filtration.

BN primarily affects adolescents and young adults. Lifetime prevalence is approximately 1% to 1.5% in the general population. It is more common in females than males, though clinical underreporting in men is significant.

• Family history of eating disorders
• Personality traits: perfectionism, impulsivity
• Participation in sports focusing on weight (e.g., gymnastics, wrestling)
• History of childhood obesity
• Sociocultural pressure regarding body image

A. Early Symptoms

• Preoccupation with body weight


• Social withdrawal during mealtimes


• Secretive food consumption


• Excessive exercise regimens B. Common Symptoms


• Episodes of binge eating


• Self-induced vomiting


• Use of laxatives/diuretics


• Swollen salivary glands (parotid gland hypertrophy) C. Advanced Symptoms


• Calluses on knuckles (Russell’s sign)


• Dental enamel erosion


• Menstrual irregularities


• Chronic constipation and bloating D. Emergency Symptoms


• Hematemesis (vomiting blood)


• Severe abdominal pain (suggesting gastric perforation)


• Cardiac arrhythmias (palpitations, syncope)


• Seizures

Vitals often reveal orthostatic hypotension and bradycardia. Physical exam may show dental caries, parotid gland swelling (chipmunk facies), Russell’s sign, and dry skin. Auscultation might reveal heart murmurs if severe electrolyte imbalance exists.

A. Clinical Assessment: DSM-5 criteria; mental status exam.
B. Laboratory Testing: Electrolyte panel, CBC, renal function.
C. Imaging Studies: Generally normal; EKG required.
D. Functional Tests: Not standard.
E. Biopsy Findings: N/A.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Anorexia Nervosa (Binge-Purge subtype), Binge Eating Disorder, medical conditions causing vomiting.

Serum Electrolytes
Type: Blood Test
Purpose: Assess metabolic status.
Expected Findings: Hypokalemia, hypochloremia, metabolic alkalosis.
Interpretation: Indicates active purging.

Electrocardiogram (EKG)
Purpose: Screen for cardiac arrhythmias.
Typical Findings: Prolonged QT interval, T-wave flattening.
Clinical Importance: Crucial for assessing risk of sudden cardiac death.

• Anorexia Nervosa: Patients with BN typically maintain a near-normal body weight.
• Binge Eating Disorder: Lack of compensatory purging behaviors.
• Gastrointestinal disorders: Gastroparesis or malignancy.

• Mallory-Weiss tears
• Cardiac arrhythmia/arrest
• Chronic kidney disease
• Severe dental decay
• Osteopenia/Osteoporosis

A. Lifestyle Modifications: Structured meal planning.
B. Preventive Measures: Early intervention and school-based body image education.
C. Medical Treatment: SSRIs (Fluoxetine is FDA-approved for BN).
D. Surgical Treatment: N/A.
E. Interventional Procedures: Nutritional counseling.
F. Rehabilitation: CBT, IPT, Family-Based Therapy.
G. Emergency Management: Electrolyte replacement and psychiatric stabilization.

Recovery rates are higher for BN than Anorexia Nervosa, with approximately 50% achieving full remission with treatment. Relapse is common; long-term support is vital.

Public health focus on media literacy, self-esteem, and detecting early signs of disordered eating.
