What diagnosis (only 1, be specific) would you give for the following case example? (DSM-IV)
An adolescent female weights 95 pounds when her ideal (normal) weight should be 120 lbs. She repeatedly engages in self-induced vomiting. She exhibits an intense fear of gaining weight and avoids eating specific foods and frequently skips meals. Despite her weight, she claims she feels fat and is highly concerned with her body’s shape. Her menstruation is disrupted; she frequently skips a month or two in a row, but it has not stopped completely.
