body dysmorphic disorder (OCD glossary)

Obsessions about a body part being deformed in some way, resulting in repeated rituals involving checking, mirror checking, excessive grooming, inability to dress oneself, and avoidance behaviors. Sometimes individuals with BDD have plastic surgeries relating to their imagined defects, but the relief (if there is any) is short-lived, and soon the individual begins worrying again, or the focus of his/her BDD can change to a different body part.
