Münchausen syndrome is a term for psychiatric disorders known as factitious disorders wherein those affected feign disease, illness, or psychological trauma to draw attention or sympathy to themselves. It is also sometimes known as hospital addiction syndrome or hospital hopper syndrome. Nurses and Doctors sometimes refer to them as frequent flyers, because they return to the hospital just as frequent flyers return to the airport. However, there is discussion to reclassify them as somatoform disorder in the DSM-5 as it is unclear whether or not people are conscious of drawing attention to themselves.[1]
Münchausen syndrome is related to Münchausen syndrome by proxy (MSbP/MSP), which refers to the abuse of another being, typically a child, in order to seek attention or sympathy for the abuser.
