Section 1.1: Definition and Prevalence
These disorders present as long-lasting disturbances in eating habits and are often accompanied by distressing thoughts regarding food and body image. Eating disorders can severely affect an individual's physical health, mental state, and social interactions. Common types include anorexia nervosa, bulimia nervosa, binge eating disorder, avoidant/restrictive food intake disorder (ARFID), other specified feeding and eating disorders (OSFED), pica, and rumination disorder.
The prevalence of eating disorders can be alarming, with estimates suggesting that up to 5% of the population may be affected. These issues frequently arise during adolescence or young adulthood. While anorexia and bulimia are more commonly reported among women, they can impact individuals of all genders and ages. People suffering from eating disorders often fixate on food, body weight, or body shape, and may experience significant anxiety surrounding eating and dietary choices.
In this video, "Mental Health Minute: Eating Disorders," viewers will gain insight into the complexities of eating disorders and their impact on mental health.
Section 1.2: Common Behaviors and Risks
Typical behaviors associated with eating disorders include restricting food intake, avoiding certain foods, engaging in binge eating, purging through vomiting or laxative use, or exercising excessively. These behaviors can become compulsive and may resemble addictive tendencies.
Eating disorders predominantly affect women aged 12 to 35, but they can manifest in anyone, regardless of gender. Moreover, these disorders often co-occur with other mental health issues, including mood disorders, anxiety disorders, obsessive-compulsive disorder, and substance use disorders. While genetics can play a role in the risk of developing these conditions, they can arise even in individuals without a family history.
Chapter 2: Types and Symptoms of Eating Disorders
The video "What are eating disorders? | APA" provides a comprehensive overview of various eating disorders, discussing their definitions and implications.
Section 2.1: Anorexia Nervosa
Anorexia nervosa is marked by self-imposed starvation and significant weight loss, often resulting in a body mass index (BMI) below 18.5 in adults. This disorder has one of the highest mortality rates among psychiatric conditions, driven by an intense fear of gaining weight. Individuals may exhibit restrictive eating behaviors or excessive exercise, sometimes alternating with binge eating and purging.
Anorexia nervosa can be classified into two subtypes:
- Restricting Type: Primarily involves weight loss through dieting, fasting, or excessive exercise.
- Binge-Eating/Purging Type: Involves binge eating and/or purging behaviors, such as vomiting or laxative misuse, alongside restrictive eating patterns.
Section 2.2: Bulimia Nervosa
Bulimia nervosa is characterized by cycles of restrictive dieting followed by binge eating episodes involving high-calorie foods. Binge eating is often accompanied by a sense of losing control and is typically conducted in secrecy, leading to feelings of shame. These episodes can result in physical discomfort, such as nausea, and psychological distress.
Symptoms of eating disorders may include:
- Cessation of menstrual periods
- Dizziness or fainting due to dehydration
- Brittle hair and nails
- Cold intolerance
- Muscle weakness and loss
- Gastrointestinal issues, such as heartburn or severe constipation
- Stress fractures from excessive exercise, along with bone density loss
- Mental health challenges, including depression, anxiety, irritability, poor concentration, and fatigue.
