Body Dysmorphic Disorder is a body-image disorder with persistent and intrusive preoccupations with an imagined or slight defect in one’s appearance. Those struggling with BDD dislike area(s) of their body. In reality, the alleged defect may be a minor imperfection or even nonexistent. For the person with BDD, the flaw is significant and projecting, often causing severe emotional distress and difficulties in daily functioning (http://www.adaa.org/).
Those with BDD may engage in compulsive behaviors that appear to be similar to OCD compulsions such as frequently checking in the mirror for imperfections, asking reassurance about how one looks, and excessively doing make-up or grooming oneself.
