People with bulimia nervosa are preoccupied by their body shape and weight. Their appreciation for food causes them to binge, but their guilt afterwards causes them to purge or turn to over exercising to make up for their binge.
It is highly believed that bulimia nervosa contains psychopathological signs in its development processes in a person, meaning that mental illness and distress might play a role in the development of bulimia nervosa. Indeed, there is a correlation between people with bulimia nervosa and borderline personality disorder (Cooper, 2003). The characteristics of borderline personality bring about depression in people, as well as unstable self-image, identity, and behavior. The individual’s sense of self is also negatively affected. All of these aforementioned symptoms of borderline personality bring about negative emotions in regard to an individual’s self-image. They become uncomfortable being in their own skin, finding something wrong whenever they are presented with the opportunity.
When a person develops a mental illness that causes them to reconsider their self-image and reevaluate their sense of self, other disorders can begin to be developed, especially those relating to their self-image. If an individual feels negatively about how they look, they tend to implement means that can make them feel better about themselves. Even if they remain unpleased about how they appear to themselves, they still feel better about the fact that they are at least trying to compensate for the damage that they believe they are doing to themselves.
The symptoms that accompany bulimia nervosa are similar to those found in borderline personality disorder. The possibility of developing an eating disorder is also a symptom of borderline personality, displaying that the two disorders can go hand-in-hand with one another. Other mental illnesses that can be connected to bulimia nervosa are multiple personality disorder and
