It's not known specifically what causes body dysmorphic disorder. Like many other mental illnesses, body dysmorphic disorder may result from a combination of causes, such as:
- Brain differences. Abnormalities in brain structure or neurochemistry may play a role in causing body dysmorphic disorder.
- Genes. Some studies show that body dysmorphic disorder is more common in people whose biological family members also have the condition, indicating that there may be at least one gene associated with this disorder.
- Environment. Your environment, life experiences and culture may contribute to body dysmorphic disorder, especially if they involve negative experiences about your body or self-image.
