Have you ever spent hours worrying that something is "wrong" with the way part of your body looks, even when others reassure you it's fine? For around 2 in every 100 people, this kind of worry becomes so consuming it takes over their whole life. That's called Body Dysmorphic Disorder (BDD) — a condition closely related to OCD, where the brain keeps sending alarm signals about appearance that simply won't switch off.
Research by Hardardottir and colleagues (2019) reviewed what we know about BDD — who gets it, how common it is, and what actually helps. The findings matter: BDD usually starts in the teenage years, involves hours of daily checking behaviours (like repeatedly looking in mirrors or picking at skin), and often comes packaged with depression or severe anxiety. Many people with BDD seek cosmetic procedures hoping to "fix" the problem — but the research is clear that this rarely helps and can sometimes make things worse.
The good news? Cognitive Behavioural Therapy (CBT) and certain antidepressant medications have solid evidence behind them. CBT helps you identify the thought patterns driving the preoccupation and learn to respond differently, so your life isn't ruled by the mirror. If you find yourself consumed by worries about your appearance, please know that effective, evidence-based help is available — speaking to a psychologist is the right first step.
