Body dysmorphic disorder: understanding this body image disorder

What is dysmorphophobia? The word refers to a psychiatric disorder, not a simple physical insecurity. Clinically known as body dysmorphic disorder (BDD) in the DSM-5-TR, it is defined as an obsessive preoccupation with an imagined flaw or a slight imperfection in physical appearance, perceived as major and repulsive by the person who suffers from it.

Literally, it means "fear of deformity". The term, coined in 1891 by the Italian psychiatrist Enrico Morselli in his publication Sulla Dismorfofobia e Sulla Tafefobia, already laid the foundations of an essential distinction: the suffering is not linked to a real flaw, but to a distorted perception of the body.

What distinguishes BDD from an ordinary insecurity

Everyone has parts of their body they like less. The difference lies in intensity and consequences. In dysmorphophobia, the preoccupation takes up several hours a day, resists attempts at reasoning, and generates psychological distress that impairs daily functioning.

Perception is distorted: even when an objective physical flaw exists, it is experienced in a completely disproportionate way. The way the affected person sees themselves does not match what others can see. This perceptual distortion is at the heart of the diagnosis.

The DSM-5-TR classifies body dysmorphic disorder among the obsessive-compulsive and related disorders, underlining its closeness to OCD in terms of cognitive and behavioral mechanisms. Despite its name, it is therefore not a phobia in the clinical sense.

Confusion between these two terms is common. It deserves a direct clarification.

Dysmorphia refers to an objective, measurable bodily abnormality: a congenital malformation, a documented facial asymmetry, a visible scar. It is a physical finding, not a psychiatric diagnosis.

Dysmorphophobia, on the other hand, is a disorder of perception. The person who suffers from it is convinced they have a serious flaw, when that flaw is either nonexistent or minor in the eyes of others. The abnormality is not in the body, it is in the cognitive processing of body image.

• Dysmorphia: real physical abnormality, objectively identifiable by a doctor, treated medically or surgically depending on the case
• Dysmorphophobia: psychiatric disorder, imagined or disproportionate flaw, treated with psychotherapy and/or medication
• Key criterion: in dysmorphophobia, the distress and the associated behaviors are out of proportion to any real abnormality
• Severity: dysmorphophobia can lead to complete social isolation and a high risk of suicide

A person can have a real dysmorphia and at the same time develop dysmorphophobia if their preoccupation with that flaw goes far beyond what the clinical reality justifies. The two situations are not mutually exclusive, but their care is distinct.

The symptoms of dysmorphophobia vary in intensity but share an excessive preoccupation with physical appearance, accompanied by repetitive behaviors and social avoidance.

The most affected body areas

No part of the body is spared. The most frequently targeted areas often involve the face: the nose, the skin (acne, wrinkles, scars, redness, skin tone), the hair, the eyes, the ears, the mouth, but also the breasts, buttocks, legs and body hair. The area of concern can change over time: a patient who focused on their nose may, months later, focus on their skin or hair.

The central feature remains the focus on tiny or completely nonexistent flaws. A single pimple can take on extraordinary importance and seem monstrous to the point of preventing someone from going out with friends.

Muscle dysmorphia is considered a particular form of the disorder[7]. The preoccupation concerns muscularity and comes with excessive training, rigid diets and repeated body checking. Symptoms are more pronounced in users of anabolic steroids[6].

Repetitive behaviors and rituals

These behaviors resemble the rituals seen in OCD. The most common ones:

• Mirror checking or, conversely, total avoidance of any reflective surface
• Excessive makeup or concealment with accessories (scarf, hat, covering clothes)
• Constant comparison with the appearance of others, on the street, on social media
• Reassurance seeking from relatives or health professionals
• Skin picking or attempts to correct the supposed flaw
• Repeated recourse to cosmetic surgery, often without lasting satisfaction

These behaviors take up a large share of the person's time and energy, reinforcing the disorder rather than relieving it.

Emotional and social impact

The distress is real and intense. Social anxiety leads people to avoid situations where others can see them: school, work, public transport, meals in public. Self-esteem collapses in a spiral of persistent dissatisfaction, often accompanied by depression.

About 80% of people with the disorder have suicidal thoughts during their lifetime, and about a third make a suicide attempt[1]. These figures underline the importance of diagnosis and care. If you have suicidal thoughts, in the US you can call or text 988[9] (988 Suicide & Crisis Lifeline), which is free, confidential and open 24 hours a day. Chat is also available, including in Spanish. In the UK, Samaritans answers on 116 123[10], free, 24 hours a day. If you are in another country, please contact your local services.

An emerging phenomenon: "Zoom dysmorphia"

The term describes a preoccupation with one's face triggered or worsened by frequent video calls: seeing one's own image continuously during meetings increases the attention paid to one's appearance, and this preoccupation can trigger or worsen body dysmorphic disorder[3].

Body dysmorphic disorder is more widespread than people think. National studies estimate it at 2 to 3% of the population[1]. The figure rises in places where people go to correct their appearance: about 11% of dermatology patients, 13 to 19% in plastic surgery and 20% of rhinoplasty requests[1].

It appears to be more frequent in women, but also affects men[1]. It usually begins in adolescence[1], a period when the construction of body identity is particularly sensitive.

Identified risk factors

The exact causes remain poorly understood. Several avenues are being studied:

• Perfectionism: a meta-analysis of 34 studies and 13,107 participants finds a moderate link with symptoms, without establishing that it is the cause[4]
• Family history: a family history of OCD or anxiety disorders is a frequently mentioned lead
• Environment: social pressure around appearance, exposure to the beauty standards of the media and social networks

Without appropriate treatment, the disorder is generally chronic[1]. Spotting the signs early, especially in adolescence, makes it possible to refer people to care more quickly.

Diagnosis relies on a thorough clinical assessment carried out by a psychiatrist or a psychologist. No laboratory test or imaging can establish the diagnosis: the clinical history is the guide. Screening questionnaires exist, such as the Body Dysmorphic Disorder Questionnaire, used in dermatology in particular[8]. A test is not enough: it points toward an assessment, it does not establish the diagnosis.

DSM-5-TR criteria

For body dysmorphic disorder, the DSM-5-TR retains the following elements[1]:

• A preoccupation with at least one perceived defect in appearance that is nonexistent or slight in the eyes of others
• Repetitive behaviors in response to this preoccupation, such as mirror checking
• Significant distress or impairment in functioning
• A preoccupation that is not better explained by an eating disorder and is not due to gender dysphoria

The level of insight into the disorder is specified, as it is often poor or absent: many people remain convinced that the defect is real[1].

Distinguishing body dysmorphic disorder from other disorders

Several disorders share similar symptoms, which makes differential diagnosis essential. A panic attack produces intense anxiety but without a focus on appearance. PTSD involves an identifiable prior trauma. Hypochondria concerns the fear of having an illness, not an aesthetic defect.

Body dysmorphic disorder is also frequently associated with comorbidities: major depression, OCD, social anxiety disorder. A mental health professional trained in body dysmorphic disorder will be able to untangle these clinical pictures and propose an appropriate therapeutic strategy.

Care relies on CBT adapted to the disorder and on SSRI antidepressants, often combined in severe forms[1]. Surgery and cosmetic procedures are not recommended: they are almost always ineffective for the disorder[1]. If you are considering a procedure, talk to a mental health professional first: even once corrected, the preoccupation can shift to another area of the body.

Cognitive behavioral therapy and gradual exposure

Cognitive behavioral therapy (CBT) is the psychotherapy of choice, provided it is adapted to this disorder: cognitive restructuring, exposure and response prevention[1]. The patient and therapist build together a graded list of appearance-related situations, from the least to the most feared, while also working to reduce mirror checking and camouflaging.

A recent review of 46 studies and 2,227 people finds a large effect of CBT on associated depressive symptoms, comparable to that of SSRIs, while noting that samples are often small and trials heterogeneous[2]. In adolescents, CBT may be useful, but the evidence remains limited. A Swedish trial of internet-delivered CBT in 154 young people aged 12 to 17 is under way[5].

In this context, virtual reality exposure therapy can help the practitioner when other people's gaze and social interactions are in the foreground. With C2Care, the practitioner recreates these situations, such as a crowd, a supermarket or public speaking, in a controlled environment and directs the exposure themselves. The studies cited here do not address virtual reality in this disorder: it is a tool in the service of therapy, not a treatment in itself.

Medication

SSRI antidepressants are preferred as first-line treatment, or failing that clomipramine, often at higher doses than in depression[1].

Medication takes several weeks to take effect. In severe forms, it is generally combined with CBT[1]. Any prescription is a matter for a physician.

Specialized support and follow-up

A therapist trained in the specific features of body dysmorphic disorder makes a real difference. Regular follow-up makes it possible to adapt treatment to the patient's progress, adjust exposures and work on self-assertion. Taking part in social exposure groups can complement individual work.

Body dysmorphic disorder is generally chronic without appropriate treatment, and its most severe forms can be disabling[1]. This is why specialized care matters.

How can you help a loved one with body dysmorphic disorder?

Your instinct will probably be to repeat that the defect cannot be seen. This rarely brings relief, and seeking reassurance is one of the repetitive behaviors of the disorder. Instead, you can acknowledge the suffering without debating appearance, avoid comments about their looks, even flattering ones, and encourage a consultation. If your loved one mentions suicidal thoughts, take them seriously and call 988[9] in the US or Samaritans on 116 123[10] in the UK. In an emergency, call 911[11] in the US or 999[12] in the UK.

Key takeaways on body dysmorphic disorder

Body dysmorphic disorder is a psychiatric disorder, close to OCD, that affects about 2 to 3% of the population and usually begins in adolescence[1]. It is not just an insecurity: it takes up several hours a day and can come with suicidal thoughts. Care relies on adapted CBT and on SSRIs, not on cosmetic surgery[1]. If you recognize yourself in this article, your family doctor can be a first point of contact.
