Social anxiety disorder (SAD) and ORS have some demographic and clinical similarities. Where the social anxiety and avoidance behavior is primarily focussed on concern about body odors, ORS is a more appropriate diagnosis than avoidant personality disorder or SAD. Body dismorphic disorder (BDD) has been described as the closest diagnosis in DSM-IV to ORS as both primarily focus on bodily symptoms. The defining difference between the two is that in BDD the preoccupation is with physical appearance not body odors. Similarly, where obsessive behaviors are directly and consistently related to body odors rather than anything else, ORS is a more appropriate diagnosis than obsessive compulsive disorder, in which obsessions are different and multiple over time.
