Body Dysmorphic Disorder: Diagnosis, Treatment and Challenges in the General Practice Abstract. Body dysmorphic disorder (point prevalence: 1.7-2.4 %) is characterized by excessive preoccupation with one or more subjectively perceived blemishes of the appearance, as a result of which those affected show a high burden of disease due to avoidance behavior and time-consuming rituals, and often secondary problems (including depression, suicidal tendencies). The disorder is often accompanied by pronounced shame and is therefore associated with challenges in diagnostics, which is why the indication and specialist treatment (first-line treatment: cognitive-behavioural therapy) are usually only carried out with great latency. Family doctors can play a key role in diagnosis and treatment because of the often long-standing relationship of trust with their patients. Targeted screening, active and at the same time prudent discussion, as well as knowledge of treatment options and special features of the disease pattern (e.g. fluctuating understanding of the disease, desire for plastic surgery measures) are necessary. Against this background, the article provides an overview of the clinic, diagnostics and therapy and concludes with specific challenges and practical recommendations for family practice.
