The co-occurrence of gender dysphoria and anorexia nervosa has been described in the scientific literature. This paper presents two adolescents with gender dysphoria and pathological eating behaviors and questions with longitudinal observations the clinical meaning of anorexia nervosa symptoms (e.g., restricting eating behaviors and fear of gaining weight) in adolescents with gender dysphoria. Both received psychological evaluations at different times: at first admission to the gender dysphoria clinic (T0) and 6 months after starting treatment with gonadotropin-releasing analogues (GnRHa; T1). In both cases, treatment with GnRHa not only improved psychological functioning, but also resolved pathological eating behaviors. In fact, both adolescents reported quick restoring of healthy food habits with restricting eating behaviors as well as intensive exercise no longer needed after treatment with GnRHa. Therefore, pathological eating behaviors (e.g., food avoidance and weight loss) could be assessed as a dysfunctional coping strategy adopted to gain control over a body developing in an unwanted direction and to block irreversible physical pubertal changes. This psychopathological conceptualization of pathological eating behaviors in adolescents with gender dysphoria stresses the importance of providing, in selected cases, early medical intervention such as pubertal suppression with GnRHa. Mental health professionals should therefore perform a specific and detailed assessment on gender identity within the evaluation of apparent eating disorders in adolescents. Restrictive eating behaviors as well as the intense fear of gaining weight or of becoming fat may, in fact, be considered secondary to a gender dysphoria diagnosis instead of anorexia nervosa symptoms.
