"..But since we have a body it is indispensable that we exist also as an animal, and each time we invent a new increase of consciousness we have to put a new link in the chain that binds us to the animal, till finally it will become so long that complications will surely ensue." CG Jung

An eating disorder is a condition which affects an individuals eating habits, either as a result of their own doing (self-inflicted), or as a bodily reaction to the consumption of food. Eating disorders can range from mild mental anguish to life-threatening conditions, and can affect every aspect of an individuals daily life. According to the authors of Surviving an Eating Disorder, "feelings about work, school, relationships, day-to-day activities and one's experience of emotional well being are determined by what has or has not been eaten or by a number on a scale." Anorexia nervosa and bulimia nervosa are the most common eating disorders generally recognized by medical classification schemes, with a significant diagnostic overlap between the two. Together, they affect an estimated 5-7% of females in the United States during their lifetimes and "approximately 10% of eating disordered individuals coming to the attention of mental health professionals are male". There are several other eating disorders which are prevalent amongst certain demographics that are being investigated and defined - Rumination syndrome, Compulsive overeating, and Selective eating disorder.
