How Is Body Dysmorphic Disorder Related to OCD?

The short answer: Body dysmorphic disorder (BDD) is a separate diagnosis from OCD, but DSM-5 lists it in the same chapter: obsessive-compulsive and related disorders. Both involve intrusive, repetitive thoughts and repetitive behaviors. A 2015 review found that 27.5% of people with BDD also have OCD at some point in life. BDD differs in its focus on appearance, its poorer insight, and its higher rate of suicidal thoughts.

Is body dysmorphic disorder a type of OCD?

No. BDD is a relative of OCD, not a subtype. With DSM-5, BDD moved into the obsessive-compulsive and related disorders category, as a 2015 review of 53 studies describes. Hoarding disorder sits in the same chapter. Our article on whether hoarding disorder is a type of OCD covers that neighbor.

The grouping is still debated. The authors of that review concluded that comparative studies of BDD and OCD need more evidence to support the classification. They also suggested comparing BDD with social phobia, which is very common in people with BDD.

This matters in practice. The common types of OCD are themes inside one diagnosis. BDD is a different diagnosis with its own risks, and it needs treatment that targets appearance concerns directly.

What do BDD and OCD have in common?

Both conditions pair unwanted, repetitive thoughts with repetitive behaviors. In BDD, the thoughts center on a perceived flaw in appearance that other people see as minor or cannot see at all. The International OCD Foundation lists the common repetitive behaviors:

• Mirror checking, or avoiding mirrors.
• Excessive grooming.
• Asking others for reassurance about appearance.
• Comparing appearance with that of other people.
• Skin picking to remove or fix perceived blemishes.

These behaviors work like OCD compulsions. They bring short relief and then feed the worry. The same loop drives reassurance seeking in OCD.

The overlap goes beyond symptoms. A 2007 comparison study looked at 210 people with OCD, 45 with BDD, and 40 with both. OCD and BDD did not differ significantly in demographic features, age of onset, illness duration, and many other variables.

How is BDD different from OCD?

The same 2007 study found clinically important differences. Three stand out.

• Focus. OCD obsessions cover many themes, such as contamination, harm, or symmetry. BDD preoccupations are about appearance.
• Insight. People with BDD are more likely to be fully convinced that the flaw is real. A 2012 study compared 211 people with OCD and 68 with BDD. Most of the OCD group had excellent or good insight. Most of the BDD group had poor or absent insight.
• Suicide risk and depression. People with BDD were significantly more likely than people with OCD to have lifetime suicidal thoughts, major depressive disorder, and a substance use disorder.

A 2016 meta-analysis of 17 studies measured the suicide link. BDD was associated with about 3.6 times the odds of suicidality overall (OR 3.63, 95% CI 2.62 to 4.63). The odds ratio was 3.30 for suicide attempts and 2.57 for suicidal thoughts. The authors noted that the studies were few and of low quality, so the exact figures are uncertain.

How common is BDD, and how often does it occur with OCD?

BDD is common. A 2016 systematic review estimated the weighted prevalence at 1.9% in adults in the community and 2.2% in adolescents. A United States telephone survey of 2,048 adults found a point prevalence of 2.4% (2.5% in women and 2.2% in men).

Rates are much higher in cosmetic settings. The 2016 review estimated 13.2% in general cosmetic surgery, 20.1% in rhinoplasty patients, and 11.3% in dermatology outpatients. The authors concluded that BDD is poorly identified in these settings.

The two disorders often occur together. The 2015 review found lifetime OCD in 27.5% of people whose main diagnosis was BDD. Lifetime BDD occurred in 10.4% of people whose main diagnosis was OCD. Having both is harder than having one. In the 2007 comparison, the group with both disorders showed greater morbidity than the OCD-only group.

OCD is not the most frequent companion. A study of 293 people with BDD found a mean of more than two other lifetime disorders. Major depression and social phobia were among the most common, along with OCD and substance use disorders. depression.md and anxiety.md cover those conditions.

How is BDD treated?

Treatment for BDD borrows from OCD treatment. The UK NICE guideline CG31 covers both disorders. For adults with BDD, it recommends:

• Mild impairment: a course of cognitive behavioral therapy (CBT), including exposure and response prevention (ERP), that addresses key features of BDD.
• Moderate impairment: the choice of an SSRI or more intensive individual CBT with ERP.
• Severe impairment: combined treatment with an SSRI and CBT with ERP.

The evidence for therapy is good but small. A 2016 meta-analysis of seven randomized trials with 299 participants found CBT superior to waitlist or placebo therapy for BDD symptoms. CBT also improved depression and insight, and gains held at 2 to 4 months. The authors still saw substantial room for improvement. Our guide to ERP therapy for OCD explains how exposure work runs.

The medicine evidence is also limited. In a 12-week placebo-controlled trial of fluoxetine, 18 of 34 people (53%) responded to the drug and 6 of 33 (18%) responded to placebo. People with delusional beliefs responded as often as those without. NICE names fluoxetine as the first drug choice for adults with BDD, because it has more evidence than other SSRIs.

No medicine is FDA-approved for BDD. The International OCD Foundation states this plainly, and NICE labels fluoxetine for BDD as off-label use. Doctors prescribe SSRIs for BDD on the strength of trial data and clinical experience. The foundation notes that benefit can take from 2 to 3 weeks up to about 14 weeks to start. Dose decisions belong to the prescriber. Our article on why SSRI doses for OCD are higher gives the background for OCD.

Do cosmetic procedures help BDD?

Rarely. A study of 200 people with BDD examined surgical and minimally invasive cosmetic treatments. These procedures sometimes reduced worry about the treated body part. Overall BDD severity improved after only 2.3% of them. Rhinoplasty was the procedure most often sought and received.

The authors offered a likely reason. People with BDD usually have several appearance concerns, so fixing one body part leaves the others. Many early improvements did not last.

NICE responds to this risk directly. People with suspected or diagnosed BDD who seek cosmetic surgery or skin treatment should first be assessed by a mental health professional with BDD expertise.

The bottom line

BDD and OCD are related but separate. They share obsessive thoughts, repetitive behaviors, and first-line treatments: CBT with exposure and response prevention, and SSRIs. BDD stands apart in its appearance focus, poorer insight, and higher suicide risk. About 1 in 4 people with BDD also have OCD in their lifetime. No medicine has FDA approval for BDD, and cosmetic procedures rarely improve it. If appearance worries take more than an hour a day or disrupt your life, ask a mental health professional about BDD.
