What causes body dysmorphic disorder (BDD)?

The exact cause of body dysmorphic disorder is not known. One theory suggests that there are problems with certain neurotransmitters (chemicals that help nerve cells in the brain send messages to each other). Body dysmorphic disorder often occurs in people with other mental health disorders, such as major depression and anxiety, which helps support this theory.

Other factors that might influence the development of or trigger body dysmorphic disorder include:

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