Study Notes

Eating Disorders

Bulimia nervosa is marked by recurrent episodes of binge eating followed by purging behaviors, such as self-induced vomiting, laxative abuse, or excessive exercise.
Anorexia nervosa involves severe restriction of food intake, leading to significantly low body weight, often accompanied by intense fear of gaining weight and distorted body image.
Binge eating disorder involves recurrent episodes of binge eating without subsequent purging behaviors.
Eating disorders are characterized by an overwhelming desire to be thin.
The strongest contributing factors to eating disorders are sociocultural rather than psychological or biological.

Bulimia Nervosa

Bulimia nervosa involves recurrent episodes of binge eating characterized by consuming significantly larger amounts of food than most people would in similar circumstances, feeling a lack of control during the binge, and subsequent attempts to compensate for the binge by purging.
Purging behaviors include self-induced vomiting, laxative abuse, diuretic use, excessive exercise, and fasting.
Purging is not effective in reducing caloric intake, with self-induced vomiting reducing approximately 50% of consumed calories, and laxatives having minimal effects.
Medical consequences of bulimia nervosa include salivary gland enlargement, dental enamel erosion, esophageal tears, electrolyte imbalance, intestinal problems, and calluses on fingers due to repeated self-induced vomiting.
Bulimia nervosa is often associated with anxiety and mood disorders, particularly depression.
There is evidence suggesting that depression may be a consequence of bulimia nervosa and that the two disorders may be interconnected.

Eating Disorders

Bulimia Nervosa is characterized by out-of-control eating episodes (binges), and attempts to purge the food by self-induced vomiting, excessive laxatives, or other methods.
Anorexia Nervosa involves minimal food intake or excessive exercise to counteract food intake, which can lead to dangerous weight loss.
Binge-Eating Disorder involves repeated binges which individuals find distressing, but they do not attempt to purge the food.
The primary characteristic of eating disorders is an overwhelming drive to be thin.
Sociocultural factors contribute significantly to eating disorders in comparison to psychological or biological factors.

Clinical Description of Bulimia Nervosa

Hallmark of Bulimia Nervosa is eating a larger volume of food, usually junk food, than most people would under similar circumstances.
Key aspect of Bulimia Nervosa is the feeling of loss of control during eating episodes.
To counter the effects of binge eating and potential weight gain, individuals utilize purging techniques.
Purging techniques include:
- Self-induced vomiting
- Laxative use
- Diuretics
- Excessive exercise
- Prolonged fasting
Purging is not an effective method of reducing caloric intake.
- Vomiting only reduces approximately 50% of the calories consumed, and is less effective if delayed.
- Laxatives and related procedures have little effect, as they act long after the binge.

Medical Consequences of Bulimia Nervosa

Repeated vomiting can lead to:
- Enlarged salivary glands, causing a chubby facial appearance.
- Erosion of dental enamel on the inner surface of front teeth.
- Tears in the esophagus.
- Electrolyte imbalance, which may result in cardiac arrhythmia, seizures, and renal failure if untreated.
Laxative abuse can cause:
- Severe constipation.
- Permanent colon damage.
People with Bulimia often have calluses on their fingers or the backs of their hands, caused by repeatedly stimulating the gag reflex to vomit.

Associated Psychological Disorders

Anxiety and Mood Disorders are commonly associated with Bulimia Nervosa.
Depression often co-occurs with Bulimia Nervosa.
One theory suggests that eating disorders are a manifestation of depression.
Evidence indicates that depression may follow Bulimia Nervosa.
