Body dysmorphic disorder (BDD), also termed body dysmorphia or dysmorphic syndrome, but originally termed dysmorphophobia, is a mental disorder via obsessive preoccupation with a perceived defect in one's own appearance, viewed as so severe as to warrant exceptional measures to hide or fix it.[1] In BDD's delusional variant, the flaw is imagined.[2] If the flaw is actual, its importance is severely exaggerated.[2] Distinguished from anorexia nervosa, BDD is categorized in the obsessive–compulsive spectrum.

A fairly common mental disorder, affecting some 1% to 2% of the population, BDD usually starts during adolescence, and affects men and women roughly equally.[2] (The BDD subtype muscle dysmorphia, whereby one obsesses that one's body or some part of it is too small.) In fear of being thought vain, persons experiencing BDD tend to keep the preoccupation secret, and BDD is severely underdiagnosed.[2] Severely impairing quality of life, BDD can lead to social isolation and involves especially high rates of suicidal ideation.[2]

Signs and symptoms[edit]

Whereas vanity concerns preoccupation with aggrandizing the appearance, BDD is compulsion to merely normalize the appearance.[2] While associating with perfectionism, BDD also reflects negative body image, [3] and shares features with obsessive-compulsive disorder (OCD),[4] but manifests greater levels of depression and social avoidance.[1] BDD is often associated with social anxiety disorder.[5]

In BDD, the perceived bodily defect can be at virtually any area, yet is usually the nose, skin, or hair.[2] Attempts at self-treatment can paradoxically create lesions where none previously existed.[2] BDD often drives a quest to obtain dermatological treatment or cosmetic surgery, which interventions typically do not resolve the distress.[2] Sometimes deluded in believing that persons are covertly pointing out their flaws, some persons experiencing BDD can react violently to perceived putdowns.[2]

Most generally, one experiencing ruminates over the perceived bodily defect up to several hours daily, uses either social avoidance or camouflaging with cosmestics or apparel, repetitively checks the appearance, compares it to that of other persons, and might often seek verbal reassurances.[2][1] BDD's severity can wax and wane, and flareups tend to yield absences from school, work, or socializing, sometimes leading to protracted social isolation.[2] Severely impairing quality of life, BDD typically involves distress exceeding that of either major depressive disorder or type-2 diabetes, and rates of suicidal ideation and attempts are especially elevated.[2]


As with most psychiatric diagnoses, BDD seems to have a causation that is biopsychosocial, an interaction of genetic, developmental, psychological, and social factors.[6] Though genetic studies into BDD are few, twin and family studies have demonstrated a significant genetic contribution towards obsessive-compulsive disorder (OCD), which BDD has been shown to be related to.[7] One study comparing the concordance rates of BDD between monozygotic twins and dyzygotic twins estimates heritability at 43%.[8] Other contributing factors to the disorder include personality trait introversion,[9] childhood abuse and neglect[6][10] and a heightened aesthetic sensitivity.[6]


Estimates of prevalence and gender distribution have varied widely via discrepancies in diagnosis and reporting.[1] In American psychiatry, BDD gained diagnostic criteria in the DSM-IV, but clinicians' knowledge of it, especially among general practitioners, is constricted.[11] Meanwhile, the shame that persons feel about having the bodily concern, and fearing the stigma of vanity, hinders recognition.[2][12] BDD is sometimes mistaken for major depressive disorder or social phobia.[13] BDD is severely under-diagnosed even in psychiatric patients.[14] Correct diagnosis calls for specialized questioning and correlation with emotional distress or social dysfunction.[14] Estimates place the Body Dysmorphic Disorder Questionnaire's specificity at 92.5% and its sensitivity at 100%.[15]


BDD's delusional variant does not respond to treatment with antipsychotic drugs, but instead with some antidepressant drugs: the selective serotonin reuptake inhibitors (SSRIs).[2] Also considered effective is cognitive-behavioral therapy (CBT).[16][17][18]


In 1886, Enrico Morselli reported a disorder that he termed dysmorphophobia.[19] In 1980, the American Psychiatric Association recognized the disorder in the third edition of its DSM—the Diagnostic and Statistical Manual of Mental Disorders—while identifying it as a somatoform disorder. The manual's 1987 revision switched the term to body dysmorphic disorder. Published in 1994, DSMs fourth edition defines BDD as a preoccupation with an imagined or trivial defect in appearance, a preoccupation causing clinically significant distress or dysfunction—socially, occupationally, or educationally—and not better explained as another disorder, such as anorexia nervosa.[20] Published in 2013, the DSM-5 shifts BDD to a new category, obsessive–compulsive spectrum, adds operational criteria, such as repetitive behaviors or mental acts, and notes the subtype muscle dysmorphia: perceiving one's body as too small or insufficiently muscular or lean.


Neuroimaging[21] suggest weaker connection between the amygdala (involved in basic emotions) and the orbitofrontal cortex (involved in regulation of emotional arousal).[22] Cognitive-behavioral therapy may improve connections between the orbitofrontal cortex and the amygdala.[22][not in citation given]
