Body dysmorphic disorder (BDD), also termed
body dysmorphia or
dysmorphic syndrome, but originally termed
dysmorphophobia, is a mental disorder characterized by an obsessive preoccupation that some aspect of one's own appearance is severely flawed and warrants exceptional measures to hide or fix it. In BDD's delusional variant, the flaw is imagined. If the flaw is actual, its importance is severely exaggerated. Either way, one's thoughts about it are pervasive and intrusive, occupying up to several hours a day. The
DSM-5 categorizes BDD in the
obsessive–compulsive spectrum, and distinguishes it from
anorexia nervosa.
