Muscle dysmorphia is variant of body dysmorphic disorder that is often referred to as bigorexia. Individuals with muscle dysmorphia become obsessed with the belief that their body does not have enough muscle size or definition. These individuals usually participate in compulsive behaviors to compensate for their perception that they are not big enough. Some of these compulsive behaviors entail extensive and elaborate exercise routines, excessive monitoring of diet, checking mirrors and other reflective surfaces, and comparisons to other people perceived as having a more muscular physique. Individuals with muscle dysmorphia may avoid traveling or going to places where they will not be able to participate in their exercise routine out of concern that they may become smaller or weaker if they miss a work-out.
