There is no single cause for these disorders which include anorexia nervosa and bulimia. However, society's emphasis on physical appearance and leanness as a means of achieving success and beauty often play a role in their development. As people become more aware of their weight and appearance many choose to diet in an attempt to conform to society's standards. Many eating disorders begin as diets.
Anorectics often feel they lack control over their lives.
Because no one can tell them what or how much to eat, eating becomes an issue of control. Anorexia nervosa can and does cause several health problems. Bulimia is an eating disorder which involves occasional to frequent binge eating, usually followed by purging. Common purging methods are vomiting, use of laxatives, diuretics, or excessive exercise. When on a binge the bulimic will uncontrollably eat large quantities of food in a relatively short period of time.
