An anorexic may become bulimic.
Some experts consider compulsive overeating to be an eating disorder also.
Anorexia is seen in an intense fear of becoming fat, failure to maintain a minimal body weight, and in the advanced stages includes the symptoms of malnutrition. Anorexia is often clearly visible through the emaciated appearance of the individual. Bulimics on the other hand are often near normal weight. Both disorders are often initially experienced in the teenage years and predominately affect women. Similar to alcoholism or addiction, compulsive overeating is uncontrolled eating in response to emotional stress.
