adjective dys·mor·phic \dis-ˈmȯr-fik\
BDD is a body-image disorder characterized by persistent and intrusive preoccupations with an imagined or slight defect in one’s appearance.
People with BDD can dislike any part of their body, although they often find fault with their hair, skin, nose, chest, or stomach. In reality, a perceived defect may be only a slight imperfection or nonexistent. But for someone with BDD, the flaw is significant and prominent, often causing severe emotional distress and difficulties in daily functioning.
BDD most often develops in adolescents and teens, and research shows that it affects men and women almost equally. About one percent of the U.S. population has BDD.
The causes of BDD are unclear, but certain biological and environmental factors may contribute to its development, including genetic predisposition, neurobiological factors such as malfunctioning of serotonin in the brain, personality traits, and life experiences.
