Body Dysmorphic Disorder

Body dysmorphic disorder is a condition that involves obsessions, with how you look on the outside. People with BDD might focus on what they think is a facial flaw, but they can also worry about other body parts, such as short legs, breast size, or body shape. Just as people with eating disorders obsess about their weight, people with BDD become obsessed over an aspect of their appearance.
People with BDD may worry their hair is thin, their face is scarred, their eyes aren't exactly the same size, their nose is too big, or their lips are too thin.
BDD has been called "imagined ugliness" because the appearance issues the person is obsessing about usually are so small that others don't even notice them. Or, if others do notice them, they consider them minor. But for a person with BDD, the concerns feel very real, because the obsessive thoughts distort and magnify any tiny imperfection.
Besides obsessions, BDD also involves compulsions and avoidance behaviors. A compulsion is something a person does to try to relieve the tension caused by the obsessive thoughts.
It's extremely upsetting to be tormented by thoughts about appearance imperfections. These thoughts intrude into a person's awareness throughout the day and are hard to ignore. People with mild to moderate symptoms of BDD usually spend a great deal of time grooming themselves in the morning. Throughout the day, they may frequently check their appearance in mirrors or windows. In addition, they may repeatedly seek reassurance from people around them that they look OK.
