Introduction and 9.1 Anorexia
Current Perception of Thinness
Western society equates thinness with health and beauty.
In the U.S., thinness has become a national obsession.
Increased preoccupation with food quantity rather than quality, taste, or nutritional value.
Rise of Eating Disorders
Notable increase in eating disorders over the last three decades.
Anorexia Nervosa: Intense fear of gaining weight, often leading to severe weight loss and possible starvation.
Bulimia Nervosa: Characterized by binge eating followed by methods to prevent weight gain (vomiting, laxatives).
Binge Eating Disorder: Involves binge eating without purging; less fear of weight gain compared to the other disorders.
Media Influence and Awareness
Surge in public interest due to medical consequences related to eating disorders.
First major awareness occurred in 1983 with the death of singer Karen Carpenter, who struggled with anorexia.
Disorders disproportionately affect adolescent girls and young women.
Overview of Anorexia Nervosa
Characteristics include:
Maintenance of a significantly low body weight.
Intense fear of obesity.
Distorted perception of weight and body shape.
Excessive impact of weight on self-evaluation.
Types of Anorexia Nervosa:
Restricting Type: Substantial food intake reduction and elimination of high-calorie foods.
Binge Eating/Purging Type: Binge eating followed by purging behaviors (vomiting, laxatives).
Historical Context
Historical admiration of self-restraint in eating, especially among saints in the Middle Ages.
Examples:
Catherine of Siena used extreme measures to avoid food.
Demographics and Statistics
Approximately 75% of anorexia nervosa cases occur in women and adolescent girls.
The disorder can start at any age but peaks between adolescence and early adulthood.
Estimated lifetime prevalence of anorexia nervosa is around 0.6%.
Onset and Progression
Often begins after dieting, especially after stressful life events (e.g., parental separation, moving, personal failure).
About 6% mortality rate due to severe health complications or suicide; suicide rate among sufferers is five times that of the general population.
Psychological and Cognitive Features
Individuals exhibit:
Distorted body image; overestimation of body size.
Preoccupation with food, often leading to obsessive thoughts and behaviors.
Rigid eating rules and compulsive exercise habits.
Common psychological issues include anxiety, depression, and low self-esteem.
Medical Consequences
Numerous physical health issues can arise including:
Amenorrhea (absence of menstrual cycles).
Low body temperature, blood pressure, body swelling, reduced bone density, and slow heart rates.
Nutritional deficiencies leading to brittle nails, rough skin, hair loss, and cold extremities.
Example of the impact: A young woman recounts personal experiences of severe physical decline due to her disorder.
Summary of Anorexia Nervosa
Extreme drive for thinness, intense fear of weight gain, distorted body perceptions.
The prevalence is alarming, with about 0.6% of people developing anorexia nervosa in their lifetime, predominantly affecting young women.
Cultural trends toward thinness further contribute to the rise in this disorder, as evidenced by changes in model sizes over the years (e.g., models being 8% thinner than the average woman in 1968 and 23% thinner in more recent years).
