Overeating


            This paper discusses the implications of overeating, the biological, psychological, and social causes of it, its impact on mental and physical aspects of health, and possible treatments.
             What is Overeating?.
             Overeating, also known as compulsive eating, or binge eating disorder is defined as eating uncontrollably without any sign of physiological hunger. It is often used as a coping mechanism to deal with issues such as stress, emotional upsets and daily problems. The food can block out feelings and emotions. And like other eating disorders, it is done in secret. Therefore, one may eat normally in public and for instance, "eat in their car afterwards in private" (Current Health, 1997). At this point, one should note that what distinguishes overeating from bulimia (binging and purging) is that both undergo approximately the same amount of overeating, however bulimics tend to vomit afterwards, while overeaters do not. .
             A feeling of guilt, shame, disgust, and depression afterwards often follows overeating. According to Diane Neumark-Sztainer and Mary Story (1998), shame turns the "normal" experience of overeating into a repetitive anguished pattern. Thus, he is saying that once they have started eating and have gotten the feeling of shame and the thought of no will power, they engage in more eating with the "now-that-I've-blown-it-I-might-as-well-eat-more" syndrome (Carol, 1997). This repetitive pattern only causes more distress and addiction to overeating as their feeling of inadequacy intensifies. .
             Causes .
             On a biological point of view, dopamine, particularly the D2 receptor, is involved with satisfaction of eating and regulates food intake. According to Genet-Jean Wang et al (2001), they found that dopamine receptors were less available in obese persons, and suggest that overeating is a method of compensating for this deficiency. Moreover, drugs that block dopamine D2 receptors increase appetite and weight gain, while drugs that increase dopamine concentration are "anorexigenic" (Wang et al, 2001).
