Understanding Anorexia Nervosa: Symptoms, Behaviors, and Cognition
Understanding Anorexia Nervosa
Anorexia nervosa is an eating disorder characterized by self-induced weight loss driven by a pathological concern about body shape and weight. This concern leads to excessive control over food intake. Individuals with anorexia experience a progressive loss of appetite and a perceived need to restrict food. While it commonly emerges during adolescence (ages 14-18), it can also occur in older adults (ages 20-40). Although more prevalent in women, anorexia also affects men.
Key Characteristics of Anorexia Nervosa
Dietary Habits
- Anorexic individuals significantly reduce or completely eliminate food consumption, often selecting foods that promote weight loss.
- They may meticulously track daily calorie intake and exhibit obsessive behaviors around meals.
- Some individuals may consume the same foods daily to maintain a sense of control.
Behavioral Patterns
- Individuals with anorexia often engage in deceptive behaviors, particularly towards family, to avoid eating.
- To accelerate weight loss, especially in the initial stages, they may engage in excessive physical exercise and misuse laxatives and diuretics.
- They may show an unusual interest in food, often taking pleasure in feeding others, viewing it as a personal victory.
- As the disorder progresses, individuals may become withdrawn and isolated, avoiding social contact due to anxieties surrounding eating or concerns about their appearance.
Cognitive Characteristics
- Anorexia nervosa is associated with an overestimation of the importance of body shape, leading to an insatiable desire for thinness.
- Individuals may experience a distorted body image, perceiving themselves as larger than they are.
- They may also suffer from depression, anxiety (ranging from mild to severe), sadness, irrational thoughts, and self-harming behaviors.
