Body Dysmorphic Disorder (BDD) most often begins during early adolescence, and it can occur even in young children. BDD appears to affect slightly more females than males. It occurs around the world, in both Western and non-Western cultures. People with BDD come from a variety of backgrounds, different socioeconomic groups and have varying levels of education. In other words, BDD can affect anyone.
It's important to realize that not all appearance concerns in adolescents are normal or simply a passing "phase"; sometimes they're BDD. If they are BDD, they need to be treated. If BDD isn't treated, normal development can be derailed, and long-term academic, occupational, and social problems can develop.
