Body Dysmorphic Disorder (BDD) – an anxiety disorder whereby sufferers have a distorted view of how they look – can manifest itself in myriad ways. The constant checking of appearance in a mirror – or the total avoidance of reflective surfaces; compulsive skin picking; seclusion; cosmetic surgery. These behaviours can shut sufferers off from the world and trap them in a cycle of fear and self-loathing. In the most extreme cases, BDD can lead to suicide.
Despite the odd celebrity confession, it's still a "new" condition in terms of understanding and public awareness. It was only recognised as being on the 'obsessive-compulsive spectrum' related to OCD in 2013. One in 100 people in the UK are thought to suffer from the disorder, although it is likely this number is higher. Experts in the field tend to agree that Cognitive Behavioural Therapy (CBT), along with anti-anxiety meds are currently the recommended starting point for therapists and doctors to go about treating it. But there's also a "human problem-solving process" that's been with us a while longer: manifesting and facing our vexations through art.
