Bulimia Nervosa
Moderate
Bulimia nervosa is an eating disorder characterized by repeated episodes of binge eating followed by behaviors intended to prevent weight gain, such as self-induced vomiting or misuse of laxatives. People may feel a loss of control during binge episodes and experience intense concern about body weight or shape. The disorder can occur at any body size and may not be obvious to others. Repeated compensatory behaviors can cause serious physical complications, including electrolyte disturbances, dental damage, gastrointestinal problems, and heart-related abnormalities.

When to Seek Medical Attention
Bulimia nervosa requires professional assessment because recurrent bingeing and purging can cause dehydration and dangerous electrolyte or heart problems. Seek prompt care for persistent vomiting, weakness, dizziness, fainting, dehydration, or symptoms suggesting an electrolyte disturbance. Emergency evaluation is needed for fainting, severe chest symptoms, confusion, seizures, severe weakness, or other signs of medical instability.

Overview

Causes 1
Bulimia nervosa develops through a combination of biological, psychological, social, and environmental factors rather than a single cause. Genetic and biological factors may increase vulnerability, while concerns about body weight and shape can contribute to disordered eating patterns. Dieting, pressure to achieve a particular appearance, stressful life experiences, and certain personality or emotional factors may play a role. The condition can become reinforced by a cycle of binge eating, guilt or distress, and compensatory behaviors.
Stress
Risk Factors
Risk factors for bulimia nervosa include a history of dieting, strong concerns about body weight or shape, pressure related to appearance, family or personal vulnerability to eating disorders, and certain psychological or emotional difficulties. Adolescence and young adulthood are common periods for onset, although the disorder can occur at any age. Social pressures, stressful experiences, and environments that emphasize weight or appearance may contribute, but no single factor causes bulimia.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis of bulimia nervosa involves a detailed assessment of eating patterns, binge episodes, compensatory behaviors, body-image concerns, mental health, and physical health. Clinicians may use established diagnostic criteria together with interviews and questionnaires. Physical examination and laboratory tests can identify complications such as dehydration or electrolyte abnormalities. An electrocardiogram may be needed when purging or electrolyte disturbance creates a risk of heart rhythm problems. Assessment should also consider other eating disorders and medical conditions.
