The actual causes of anorexia nervosa and other eating disorders are still not fully understood, but science has identified some potential contributing factors for these conditions. A combination of possible triggers all combine to cause eating disorders in individuals. There are physical factors, emotional issues, and social factors that can all combine to cause anorexia nervosa. When you engage in constant or extreme dieting this can change how your brain works and affect your metabolism as well. These factors can cause high amounts of stress and you are more likely to develop one or more eating disorders as a result of these stresses. Genetics also plays a role with eating disorders and can contribute to anorexia nervosa, bulimia, and even compulsive over eating. A family history of mood disorders can also trigger eating disorders.
Some personality traits can also be triggers for anorexia nervosa and other eating disorders. Someone who has a low sense of self esteem and little self confidence is more likely to strive for perfection and this can lead to eating disorders. The pressures of the current culture and the importance of thinness in modern society also help contribute to anorexia and other eating disorders. Teenagers have a very stressful time during adolescence, and this also plays a role in anorexia nervosa and eating disorders. Adolescents may engage in anorexia nervosa and other eating disorders in order to cope with the stress of negative events, such as divorce, bullying, and even the death of a loved one.
