Body Dysmorphic Disorder (BDD) and eating disorders share substantial overlap — both involve preoccupation with body image, both involve compulsive behaviors, both produce significant distress. But they’re different conditions with somewhat different treatment approaches. Distinguishing them matters; recognizing when they coexist matters even more.
This article addresses the clinical considerations of BDD and eating disorder overlap from a psychiatric perspective, with attention to appropriate care coordination.
What BDD Is
BDD criteria require:
- Preoccupation with a perceived defect or flaw in physical appearance that’s not observable or appears slight to others
- Performance of repetitive behaviors or mental acts in response to appearance concerns
- Significant distress or impairment
- Not better explained by an eating disorder
Common BDD preoccupations:
- Skin (perceived blemishes, asymmetry, color)
- Hair (thinning, color, distribution)
- Nose
- Face shape
- Specific body parts (muscle mass, particular features)
- Genitalia
How BDD Differs From Eating Disorders
Focus of preoccupation
BDD: Specific perceived appearance defect — typically focal (a feature, an area).
Eating disorders: Body weight, shape, or size — typically global body concerns. Anorexia involves intense fear of weight gain; bulimia and binge eating disorder involve preoccupation with weight/shape and eating control.
Behavioral patterns
BDD: Mirror checking, camouflaging, skin picking, excessive grooming, comparison with others, seeking reassurance, cosmetic procedure pursuit.
Eating disorders: Restriction, binging, purging, excessive exercise for weight/shape control, weighing rituals, food rituals.
Insight
BDD: Variable — many patients have limited insight that their concerns are exaggerated. Some have delusional-level conviction.
Eating disorders: Variable — anorexia particularly often has limited insight into the seriousness of the condition.
Demographics
BDD: Roughly equal in men and women, though presenting concerns differ (muscle dysmorphia more common in men).
Eating disorders: Substantially more common in women but increasingly recognized in men.
Where They Overlap
- Body image preoccupation as core feature
- Compulsive checking and reassurance-seeking
- Significant distress and functional impairment
- Comorbid depression and anxiety
- OCD-spectrum features
- Significant suicide risk
- Treatment-seeking often delayed or avoided
- Response to SSRIs (particularly at higher doses) and CBT
When They Coexist
BDD and eating disorders can occur together — with one typically being primary and the other secondary. Common patterns:
- Eating disorder with specific body part BDD (e.g., anorexia with focal abdominal preoccupation)
- BDD with disordered eating as one of the compulsions
- Muscle dysmorphia with eating patterns to support muscle gain
- Each condition potentially worsening the other
Treatment Considerations
For BDD primarily
- SSRIs at OCD-spectrum doses (often higher than typical depression dosing)
- CBT specifically for BDD — including ERP
- Address cosmetic procedure-seeking (usually not helpful)
- Sometimes augmentation with antipsychotic for delusional BDD
For eating disorders primarily
- Specialty eating disorder treatment (often higher level of care)
- Medical monitoring essential for restriction or purging
- Nutritional rehabilitation
- Family-based treatment for adolescents
- Specific therapies (CBT-E, FBT, MANTRA)
- Medication varies by eating disorder type
For coexisting conditions
- Specialty eating disorder care for the eating component (often primary)
- BDD-aware treatment for body-part preoccupations
- Coordination of medication management
- Recognition that eating disorder treatment may not address residual BDD
Why This Matters
Patients with BDD whose eating concerns are part of the BDD pattern need BDD-focused treatment — not generic eating disorder treatment that may miss the underlying condition. Patients with eating disorders who also have BDD need both addressed for complete recovery. Misidentifying which condition is primary delays effective treatment.

Wrong primary diagnosis
BDD-eating disorder overlap often gets misidentified — treating one condition when both need attention.
Careful distinction
Dr. Farkas evaluates body image conditions carefully, distinguishing BDD from eating disorders and coordinating with eating disorder specialists when needed.
Comprehensive recovery
Properly identified conditions receive matched treatment — both components addressed for complete recovery.
Common Questions About BDD and Eating Disorders
Can I have both?
Yes — comorbidity is common. Treatment then addresses both components.
How do I know which is primary?
Careful evaluation considers focus of preoccupation, types of compulsive behaviors, weight/shape concerns vs specific feature concerns, and other clinical features.
Will cosmetic surgery help my BDD?
Almost never — typically increases distress or shifts preoccupation to another feature. See our related article on body dysmorphic disorder.
Should I see a psychiatrist or eating disorder specialist?
Often both — particularly for complex presentations. Coordination produces better outcomes.
