The development of BDD is not precisely understood, but certain factors may make individuals more susceptible to it. One potential influence is genetics, as having a family member with BDD, obsessive-compulsive disorder (OCD), or depression might increase the likelihood of developing BDD. Additionally, a chemical imbalance in the brain is thought to play a role in its onset. Moreover, experiencing traumatic events in the past, such as being teased, bullied, or abused during childhood, may also contribute to the development of BDD.   It is worth noting that some individuals with BDD may also have other co-existing mental health conditions, such as OCD, generalized anxiety disorder, or an eating disorder. The interplay of these various factors can make certain individuals more prone to experiencing body dysmorphia, though the exact reasons behind its development still require further research.
