Anorexia nervosa in an elderly man.

Anorexia nervosa (AN) rarely develops after the age of 30 years, and rarely occurs in men. We report a case of chronic AN in a 72-year-old man, who reported a 20-year history of extreme low body weight, persistent fears of obesity, and feelings of being fat even at 93 lb. Also reported were episodes of self-induced vomiting, laxative abuse, and excessive exercising. Patient's scores on a battery of questionnaires were also consistent with a diagnosis of AN.
