Study Notes
Misconceptions about Eating Disorders
- Many misconceptions about eating disorders come from over-generalizations and misinformation, especially from television.
- Bulimia nervosa is often misunderstood and simplified as just "someone who throws up after they eat."
Definition of Bulimia Nervosa
- Bulimia nervosa is an eating disorder found in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition.
- It is not defined by weight, but by an eating disorder where a person displays:
- Recurrent binge eating, characterized by eating a large amount of food in a discrete period and feeling a lack of control over eating.
- Recurrent compensatory behavior to prevent weight gain.
- Binge eating and compensatory behavior occurring an average of once a week for three months.
- Self-esteem being disproportionately influenced by body shape and weight.
- Not being better explained by anorexia nervosa.
Prevalence of Bulimia Nervosa
- It is estimated that 1.1% to 4.2% of women experience bulimia during their lifetimes.
- Many more will have disordered eating patterns that don't meet the criteria for an eating disorder.
- Exact figures for men and people of other gender identities are not available, due to possible underdiagnosis and societal emphasis on fit men.
Subtypes of Bulimia Nervosa
- There are two main subtypes of bulimia nervosa:
- Purging bulimia, characterized by the removal of food through laxatives, water pills, or vomiting.
- Non-purging bulimia, characterized by restricting further calorie intake or excessive exercise.
Characteristics of Binge Eating
- Binge eating involves eating a definitively larger amount of food than most people during a discrete period.
- It is a common characteristic of bulimia nervosa.
Consequences of Bulimia Nervosa
- Repeated use of compensatory behavior can cause severe damage to the body, including:
- Malnourishment
- Bowel unresponsiveness (from laxatives)
- Kidney damage (from water pills)
- Tooth erosion, muscle damage, and eye problems (from vomiting)
- Restrictive eating patterns or excessive exercise can lead to similar but more holistic damage.
Causes of Bulimia Nervosa
- The exact cause is unknown, but stress and coping mechanisms play a significant role in its creation and continuation.
- Stress can lead to using food as an escape, which then becomes a new source of stress, creating a vicious cycle.
Treatment of Bulimia Nervosa
- Treatment can be done through:
- Education and simple stress management techniques (for mild forms)
- Cognitive-behavioral therapy, focusing on identifying and changing unhealthy thoughts and behaviors
- Family-based therapies, targeting unrealistic expectations and stressors
- Pharmaceutical approaches, such as antidepressants (but with close monitoring of side effects)
- Severe cases may require hospitalization to address extensive damage to the body.
- Early treatment has the best prognosis, as the longer it takes to treat, the more ingrained the behavior pattern becomes.
