Body dysmorphic disorder usually begins during adolescence and may be somewhat more common among women. At any given point in time, about 1.7 to 2.9% of people have the disorder.
Symptoms and Signs of Body Dysmorphic Disorder
Symptoms of body dysmorphic disorder may develop gradually or abruptly. Although intensity may vary, the disorder is thought usually to be chronic unless patients are appropriately treated. Concerns commonly involve the face or head but may involve any body part or any number of parts and may change from one part to another over time. For example, patients may be concerned about thinning hair, acne, wrinkles, scars, vascular markings, color of their complexion, or excessive facial or body hair. Or they may focus on the shape or size of the nose, eyes, ears, mouth, breasts, buttocks, legs, or other body part. Men (and rarely women) may have a form of the disorder called muscle dysmorphia, which involves preoccupation with the idea that their body is not sufficiently lean and muscular. Patients may describe the disliked body parts as looking ugly, unattractive, deformed, hideous, or monstrous.
Patients usually spend many hours a day worrying about their perceived defects and often mistakenly believe that people take special note of or mock them because of these perceived defects. Most check themselves often in mirrors, others avoid mirrors, and still others alternate between the 2 behaviors.
Other common compulsive behaviors include comparing their appearance with that of other people, excessive grooming, skin picking Excoriation (Skin-Picking) Disorder Excoriation disorder is characterized by recurrent picking of one's skin resulting in skin lesions.

Most try to camouflage their perceived defects—eg, by growing a beard to hide perceived scars or by wearing a hat to cover slightly thinning hair. Many undergo dermatologic, dental, surgical, or other cosmetic treatment to correct their perceived defects, but such treatment is usually unsuccessful and may intensify their preoccupation. Men with muscle dysmorphia may use androgen supplements, which can be dangerous.
Because people with body dysmorphic disorder feel self-conscious about their appearance, they may avoid going out in public. For most, social, occupational, academic, and other aspects of functioning are impaired—often substantially—because of their concerns about appearance. Some leave their homes only at night; others, not at all. Social isolation, depression, hospitalization, and suicidal behavior are common. In very severe cases, body dysmorphic disorder is incapacitating.
The degree of insight varies, but it is usually poor or absent. That is, most patients genuinely believe that the disliked body part probably (poor insight) or definitely (absent insight or delusional beliefs) looks abnormal, ugly, or unattractive.
Over their lifetime, about 80% of people with body dysmorphic disorder experience suicidal ideation, and about one quarter to nearly 30% attempt suicide (see Suicidal Behavior Suicidal Behavior Suicide is death caused by an intentional act of self-harm that is designed to be lethal.

Diagnosis of Body Dysmorphic Disorder
Because many patients are too embarrassed and ashamed to reveal their symptoms, body dysmorphic disorder may go undiagnosed for years. It is distinguished from normal concerns about appearance because the preoccupations are time-consuming and cause significant distress, impairment in functioning, or both.
Diagnosis of body dysmorphic disorder is based on history. If the only concern is body shape and weight and eating behavior is abnormal, an eating disorder Anorexia Nervosa Anorexia nervosa is characterized by a relentless pursuit of thinness, a morbid fear of obesity, a distorted body image, and restriction of intake relative to requirements, leading to a significantly... read more may be the more accurate diagnosis; if the only concern is the appearance of physical sex characteristics, a diagnosis of gender dysphoria Gender Dysphoria Sex and gender are not the same thing.

Diagnostic criteria for body dysmorphic disorder include the following:
Preoccupation with one or more perceived defects in appearance that are not observable or appear only slight to others
Performance of repetitive behaviors (eg, mirror checking, excessive grooming) in response to the appearance concerns at some point during the disorder
The preoccupation causes significant distress or impairs social, occupational or other areas of functioning
Treatment of Body Dysmorphic Disorder
Selective serotonin reuptake inhibitors (SSRIs) and clomipramine plus, in some cases, an augmenting medication
SSRIs Selective Serotonin Reuptake Inhibitors (SSRIs) Several drug classes and drugs can be used to treat depression: Selective serotonin reuptake inhibitors (SSRIs) Serotonin modulators (5-HT2 blockers) Serotonin-norepinephrine reuptake inhibitors... read more and clomipramine (a tricyclic antidepressant with potent serotonergic effects), are often very effective in patients with body dysmorphic disorder. Patients often require higher doses than are typically needed for depression and most anxiety disorders. Although data are limited, some patients who do not substantially improve with adequate trials of these drugs may benefit from addition of augmenting medication such as an atypical neuroleptic (eg, aripiprazole), buspirone, or a glutamate modulator (eg, N-acetylcysteine).
Cognitive-behavioral therapy that is tailored to the specific symptoms of body dysmorphic disorder is currently the psychotherapy of choice. Cognitive approaches (eg, cognitive restructuring) and exposure and ritual prevention are essential elements of therapy. Clinicians encourage patients to gradually face situations they fear or avoid while refraining from performing their rituals.
Cognitive-behavioral therapy also includes other elements such as perceptual retraining and habit reversal training for skin picking or hair pulling or plucking if present. Habit reversal training includes the following:
Awareness training (eg, self-monitoring, identification of triggers for the behavior)
Stimulus control (modifying situations—eg, avoiding triggers—to reduce the likelihood of initiating the behavior)
Competing response training (teaching patients to substitute other behaviors, such as clenching their fist, knitting, or sitting on their hands, for the excessive behavior)
Because most patients have poor or absent insight, motivational techniques are often needed to increase their willingness to participate and stay in treatment.
Many experts believe that combining cognitive-behavioral therapy with drug therapy is best for severe cases.
Patients are preoccupied with ≥ 1 perceived defects in their physical appearance that are not apparent or appear only slight to other people.
At some point during the disorder, patients respond to their appearance concerns by performing repetitive behaviors (eg, mirror checking, excessive grooming) and/or taking measures to camouflage or remove the perceived defect.
Patients typically have poor or absent insight and genuinely believe that the disliked body area looks abnormal or unattractive.
Treat using cognitive-behavioral therapy that is tailored specifically to body dysmorphic disorder and/or drug therapy with an SSRI or clomipramine, often at relatively high doses.
