What Is Bulimia Nervosa?
Bulimia nervosa, commonly known as bulimia, is a serious eating disorder characterized by cycles of binge eating followed by compensatory behaviors such as vomiting, fasting, or excessive exercise to prevent weight gain.
Unlike what many people assume, you cannot always tell whether someone has bulimia just by looking at them. People with bulimia often maintain a normal body weight or may even appear slightly overweight, making the condition harder to detect.
Both bingeing and purging typically occur in secret, driven by feelings of shame, guilt, or loss of control. Individuals struggling with bulimia often also face coexisting psychological disorders, such as trầm cảm, lo âu, hoặc sử dụng chất rối loạn.
Physically, bulimia can lead to severe health issues, including:
Electrolyte imbalances (which can cause heart complications)
Gastrointestinal problems
Severe dental erosion due to stomach acid from vomiting
Dehydration and fatigue
According to research, 1-4% of females will experience bulimia at some point in their lifetime, while the condition is less common among males. The disorder most often begins in late adolescence or early adulthood, though some cases remain undiagnosed until later in life.
What Causes Bulimia Nervosa?
The development of bulimia is multifactorial – involving a combination of biological, psychological, and social influences.
1. Psychological and Emotional Factors
Bulimia is often triggered by stress, dieting, or emotional distress such as anger, loneliness, or sadness. Many people with bulimia use bingeing and purging as a way to regain a sense of control when they feel overwhelmed by negative emotions.
Individuals with low self-esteem, perfectionism, or a fear of weight gain are at higher risk of developing the disorder.
2. Biological and Genetic Factors
Research shows that genetics may play a significant role. People with a family history of eating disorders, trầm cảm, or lo âu are more likely to develop bulimia. Hormonal imbalances and irregularities in brain chemicals such as serotonin – which affects mood and appetite – may also contribute.
3. Environmental and Cultural Influences
Societal pressure to be thin and cultural ideals of beauty can reinforce unhealthy body image. Exposure to media promoting unrealistic body standards can increase the desire for control over one’s appearance.
In addition, traumatic life experiences, such as bullying or abuse, may trigger the onset of disordered eating behaviors.
Common Symptoms of Bulimia
The symptoms of bulimia nervosa can be physical, emotional, and behavioral. Recognizing them early can make a significant difference in recovery.

Hiding food or eating secretly.
2. Emotional Symptoms

Intense fear of gaining weight despite normal weight range.

Mood swings, anxiety, or depressive thoughts.
3. Physical Symptoms

How Is Bulimia Treated?
Recovery from bulimia is possible with the right support and treatment approach. Successful management often combines psychotherapy, medical monitoring, and nutritional counseling.
1. Psychotherapy
The most effective form of therapy is Trị liệu Nhận thức - Hành vi (Cognitive Behavioral Therapy), which helps individuals identify and challenge negative thought patterns about food and body image.
Other therapeutic approaches include:
Trị liệu hành vi biện chứng (DBT) – focusing on emotional regulation.
Family-Based Therapy (FBT) – involving family support for adolescents.
Many factors contribute to the development of bulimia, such as genetics, traumatic life events, cultural ideals of beauty, pressure from family members, and personality traits such as tự ti.
2. Medical and Nutritional Support
Doctors may monitor for electrolyte imbalances hoặc cardiac risks. A registered dietitian can help rebuild a healthy relationship with food through meal planning and nutritional education.
3. Medication
Antidepressants, particularly SSRIs (such as fluoxetine), can help manage symptoms of depression and reduce binge-purge behaviors when used under medical supervision.
4. Building Healthy Coping Strategies
Recovery also involves learning to:
Manage stress and emotions without turning to food.
Build self-compassion and body acceptance.
Replace perfectionistic thinking with realistic goals.
