Fear of Body Deformity

That distinction carries the whole entry. A person with this condition is not trying to look better than anyone. They are trying to reach the level everyone else is assumed to be at already, and the effort is invisible to observers who read it as vanity.

The consequences are among the worst in this catalogue. Studies have reported up to sixty-nine per cent experiencing suicidal ideation and fifty per cent attempting suicide, and the distress of the condition tends to exceed that of major depressive disorder.

Why body dysmorphic disorder is hidden and overlooked

People with the condition usually hide the preoccupation, and the material names the reason: they fear the stigma of vanity.

That is a closed loop. The condition is defined by not being vanity, is mistaken for vanity by everyone who sees it, and is therefore concealed by the person who has it, which is one reason it is commonly overlooked even by psychiatrists and has been underdiagnosed.

Why body dysmorphia's prevalence estimates differ sixfold

The article carries an estimate of two to three per cent of the population, and then a large systematic review and meta-analysis putting global prevalence at approximately seventeen per cent.

Those differ by a factor of six or more and this entry does not reconcile them. What can be said is what each is attached to. The meta-analysis reports strong regional variation:

• Latin America, thirty-one per cent
• Africa, twenty-three
• Asia, seventeen
• Europe, fourteen
• North America, twelve
• Oceania, ten

Clinical settings give higher rates than community samples, and the three quoted are informative about where the condition presents: twenty-four per cent among patients seeking plastic surgery, eighteen per cent among psychiatric patients and sixteen per cent among dermatological patients.

A quarter of people in a plastic surgeon's waiting room is the figure with the most immediate practical consequence, given what follows.

Why cosmetic surgery does not fix body dysmorphia

Many people with the condition seek dermatological treatment or cosmetic surgery, and it typically does not resolve the distress.

Self-treatment is worse. Skin picking, undertaken as a correction, can create lesions where none previously existed, which converts an imagined flaw into a real one.

How often the appearance belief becomes delusional

The appearance concern is usually non-delusional, an overvalued idea rather than a fixed false belief, and it is delusional in about one case in three.

One finding in that area is genuinely startling and is reported here as the source reports it: in some studies the level of delusionality in people with body dysmorphic disorder is higher than in people with schizophrenia. Some experience delusions that other people are covertly pointing out their flaws.

Cognitive testing and neuroimaging suggest two things together: a bias toward detailed visual analysis, and a tendency toward emotional hyper-arousal. A person examining a face in unusual detail while emotionally over-aroused is a person equipped to find something.

What a day with body dysmorphia consists of

The behaviours the source records fill an ordinary day rather than punctuating it:

• rumination over the perceived defect for several hours daily or longer
• repetitive checking of the appearance, and comparison with other people
• requests for verbal reassurance
• camouflage with cosmetics or clothing, or social avoidance instead
• mirrors sometimes avoided and sometimes consulted repeatedly
• outfits changed repeatedly, grooming taken to excess, eating restricted

The area of focus is commonly the face, skin, stomach, arms and legs, and can be nearly any part of the body, with several areas possible at once. Muscle dysmorphia, also called reverse anorexia or bigorexia, is the subtype in which a muscular and trained body is perceived as too thin, and it affects mostly men.

Severity waxes and wanes, and flare-ups produce absence from school, work or company, sometimes protracted social isolation, and in some cases being housebound for extended periods. Social impairment is usually the greatest impairment, occasionally approaching avoidance of all social activity.

Where body dysmorphic disorder sits and when it starts

DSM-5 places it within the obsessive-compulsive spectrum and distinguishes it from anorexia nervosa. It involves more depression and social avoidance than obsessive-compulsive disorder despite the overlap, and it often associates with social anxiety disorder, which frequently precedes it.

Onset is usually in early adolescence and it affects men and women at roughly similar rates. One twin study estimated heritability at forty-three per cent.

The childhood findings are strong. A 2021 study of childhood maltreatment among adults with the condition found more than seventy-five per cent reporting some form of abuse as children, with emotional neglect leaving people especially vulnerable and physical and sexual abuse also significant risk factors. The mechanism proposed is that as those children reach adulthood they begin to visualise what was done to their bodies, and look for ways to hide, cover or change it so as not to be reminded.

Other named factors are introversion, negative body image, perfectionism and heightened aesthetic sensitivity. Constant social media use and selfie taking are associated with lower self-esteem and dysmorphic tendencies.
