There is a low prevalence of eating disorders among men. In many cases, the disorder arises as a means of avoiding psychosocial maturation. Various psychiatric comorbidities such as depression or obsessive-compulsive disorder are frequently found in these patients.

To analyze psychiatric symptoms in relation to a case of anorexia nervosa.

Pubmed revision on clinical presentation of anorexia nervosa in male. Review of patient medical records.

A 23-years-old male with diagnosis of restricting anorexia nervosa was treated and followed since 2012. In July 2015, the patient, who was clinically stabilized for a year, had decreased gradually intake. Suddenly he showed a decreased consciousness, followed by an absence of response and mutism that motivated hospital admission. The diagnosis was dissociative stupor. A research in women with eating disorders shows a prevalence of pathological dissociation between 4.8 and 48.6%. After recovering a normal consciousness, he presented clinical features of anorexia nervosa according DSM 5 criteria. The patient remained two months until he reached his previous BMI (17) to continue an outcome treatment. Despite of several years of specific treatment for anorexia nervosa, both parents and patient still did not accept the diagnosis. Cultural constructions of eating disorders as a “women's illness” mean that men may fail to recognise their disorder.

There is a delay of diagnosis of anorexia nervosa in men. The lack of research on men's experiences and the cultural construction of anorexia nervosa as a female problem may contribute to underdiagnose eating disorders in men.
