Review Questions

• How does anorexia nervosa specifically impact the nutritional needs and growth of adolescents?
  • Anorexia nervosa significantly impacts adolescents by disrupting their essential nutrient intake during a critical period of growth and development. Since adolescents require increased calories and nutrients to support rapid physical changes, malnutrition from this disorder can lead to stunted growth, delayed puberty, and long-term health issues. The fear of gaining weight often overrides their need for nourishment, making it vital to address these dietary deficits for recovery.
• Discuss the psychological factors that contribute to the development of anorexia nervosa in adolescents.
  • Psychological factors such as low self-esteem, perfectionism, anxiety disorders, and a history of trauma play significant roles in the development of anorexia nervosa among adolescents. Many individuals develop distorted body image perceptions influenced by societal pressures and unrealistic standards of beauty. These psychological issues can drive unhealthy eating behaviors as individuals attempt to gain control over their bodies or cope with emotional distress.
