What is typically observed in a patient with body dysmorphic disorder?

In a patient with body dysmorphic disorder, a hallmark characteristic is the preoccupation with an imagined defect or excessive concern about a slight physical flaw. This disorder causes significant distress and impairment in social or occupational functioning due to this fixation on perceived imperfections in appearance. Individuals often spend considerable amounts of time examining themselves in mirrors, seeking reassurance, or attempting to hide their perceived flaws.

The intense focus on specific aspects of their appearance is what distinguishes body dysmorphic disorder from other conditions that may involve concerns about physical appearance. While other options mention related aspects of appearance or emotions, they do not capture the essence of body dysmorphic disorder as effectively as the preoccupation with an image or physical flaw does.
