GLOSSARY

Anorexia Nervosa (Anorexia)
An eating disorder characterized by excess control - a morbid fear of obesity leads the sufferer to try and limit or reduce their weight by excessive dieting, exercising, vomiting, purging and use of diuretics. Sufferers are typically more than 15% below the average weight for their height/sex/age and typically have amenorrhea (if female) or low libido (if male). 1-2% of female teenagers are anorexic.

Bulimia Nervosa (Bulimia)
An eating disorder characterized by lack of control - abnormal eating behavior including dieting, vomiting, purging and particularly bingeing that is usually associated with normal weight or obesity (unlike anorexics, who tend to be considerably underweight). The syndrome is associated with guilt, depressed mood, low self-esteem and sometimes with childhood sexual abuse, alcoholism or promiscuity.
