Causes of Body Dysmorphic Disorder

One theory suggests BDD involves a problem with the size or functioning of specific brain areas. BDD often occurs in people with other mental disorders, such as major depression and anxiety.

Other factors that trigger BDD include:

• Experience of traumatic events or emotional conflict in childhood.
• Low self-esteem.
• Parents and others who were critical of the person's appearance.
• Pressure from peers and society that equates physical appearance with beauty and value.
