Factitious disorder, often referred to as Munchausen’s syndrome, is a condition in which sufferers present to healthcare professionals seeking investigation and treatment for signs and symptoms that they have consciously fabricated for no obvious reason. Factitious presentations have been described all over the world, in every medical specialty and in every age group, yet by its very nature factitious disorder is difficult to study. There is therefore a dearth of evidence in the literature relating to epidemiology, aetiology and therapeutics. The disorder is notoriously difficult to recognise in clinical practice and there are as yet no definitive treatment options available. This article provides a brief overview of the literature before offering guidance on the diagnosis and management of factitious disorder presenting in the general hospital. It also considers fabricated or induced illness, also known as Munchausen’s syndrome by proxy.
