Main Methods:

  • Literature review of diagnostic criteria evolution.
  • Comparative analysis of anorexia nervosa and atypical anorexia nervosa.
  • Summary of recommended monitoring protocols and treatment approaches.

Main Results:

  • The article details the diagnostic criteria and clinical presentation of both disorders.
  • Key laboratory values, vital signs, and weight monitoring are emphasized.
  • Biopsychosocial factors in etiology and treatment are discussed, alongside prognosis.

Conclusions:

  • Close monitoring of physical and psychiatric status is crucial for managing anorexia nervosa and atypical anorexia nervosa.
