Body Dysmorphic Disorder
Understanding Body Dysmorphic Disorder (BDD)
Most of us have something we don't like about our appearance — a crooked nose, an uneven smile, or eyes that are too large or too small. And though we may fret about our imperfections, they don’t interfere with our daily lives.
But people who have body dysmorphic disorder (BDD) think about their real or perceived flaws for hours each day. They can't control their negative thoughts and don't believe people who tell them that they look fine. Their thoughts may cause severe emotional distress and interfere with their daily functioning. They may miss work or school, avoid social situations and isolate themselves, even from family and friends, because they fear others will notice their flaws.
Characteristics of BDD
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. In the United States, BDD occurs in about 2.5% in males, and in 2.2 % of females. BDD often begins to occur in adolescents 12-13 years of age (American Psychiatric Association, 2013).
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 (e.g. child maltreatment, sexual trauma, peer-abuse).
