An eating disorder is marked by extremes. It is present when a person experiences severe disturbances in eating behavior, such as extreme reduction of food intake or extreme overeating, or feelings of extreme distress or concern about body weight or shape.
A person with an eating disorder may have started out just eating smaller or larger amounts of food than usual, but at some point, the urge to eat less or more spirals out of control. Eating disorders are very complex, and despite scientific research to understand them, the biological, behavioral and social underpinnings of these illnesses remain elusive.
The three main types of eating disorders are anorexia nervosa (anorexia) and bulimia nervosa (bulimia), and binge eating disorder (binge eating). A fourth category is "eating disorders not otherwise specified" (EDNOS), which includes elements of anorexia and bulimia, but doesn't meet the clinical definition of either. Binge-eating disorder, which has received increasing research and media attention in recent years, is one type of EDNOS.
Eating disorders frequently appear during adolescence or young adulthood, but some reports indicate that they can develop during childhood or later in adulthood. 85% of eating disorders start between the ages of 13-20. Women and girls are much more likely than males to develop an eating disorder. Men and boys account for an estimated 5 to 15 percent of patients with anorexia or bulimia and an estimated 35 percent of those with binge-eating disorder. (Typically 1 in 10 is a male). Eating disorders are real, treatable medical illnesses with complex underlying psychological and biological causes. They frequently co-exist with other psychiatric disorders such as depression, substance abuse, or anxiety disorders. People with eating disorders also can suffer from numerous other physical health complications, such as heart conditions or kidney failure, which can lead to death.
