APA Dictionary of Psychology

preoccupation with one’s body or any part of it. This concern may be associated with compulsive checking of the body part (e.g., in a mirror or by touch), comparing oneself to others, and seeking reassurance about one’s body. Somatic obsession is the central feature of body dysmorphic disorder but may also be a feature of obsessive-compulsive disorder if other obsessive-compulsive symptoms are present.
