Eating Disorders Definitions
Anorexia Nervosa
Anorexia nervosa literally means loss of appetite but this is a misnomer: A person with anorexia nervosa is hungry, but he or she denies the hunger because of an irrational fear of becoming fat. Anorexia nervosa is often characterized by self-starvation, food preoccupation and rituals, compulsive exercising, and often an absence of menstrual cycles. Untreated, anorexia can be fatal. It is not a "fad" which the victim will outgrow if left alone. The death of pop singer Karen Carpenter at age 32 was attributed to heart failure, following her eight-year battle with anorexia. The most common cause of death in a long-time anorexic is low serum potassium, which can cause an irregular heartbeat.
Bulimia Nervosa
Bulimia nervosa is characterized by recurring periods of binge eating, during which large amounts of food are consumed in a short period of time -- sometimes as many as 20,000 calories during the course of a single binge. The bulimic is aware that his or her eating is out of control. He or she is fearful of not being able to stop eating, and is afraid of being fat. The bulimic usually feels depressed and guilty after a binge. Frequently, the binges are followed by purging, through self-induced vomiting, abuse of laxatives and/or diuretics, or periods of fasting. The bulimic's weight is usually in a normal or somewhat above normal range; it may fluctuate more than 10 pounds due to alternating binges and fasts.
Compulsive Overeating (Binge Eating Disorder)
A compulsive overeater (binge eater) is an individual who compulsively eats but does not purge and usually becomes overweight. The overeater may eat three meals a day plus frequent snacks. He or she may overeat continually throughout the day, rather than consume large amounts of food during binges.
