There is no known prevention for BDD.
Some people with BDD function fairly well. Others may be incapacitated by their symptoms. The ability to work, do schoolwork, manage a household, attend school, and function socially can be affected.
Many people with BDD become depressed, and some may consider suicide. A person with this disorder is more likely to seek plastic surgery to "correct" the perceived flaw. In more severe cases, he or she may seek many surgeries to alter his or her looks.
Body dysmorphic disorder is not contagious and poses no risk to others. However, relationships with others may be affected.
