Munchausen’s syndrome is rare condition where a person fakes symptoms of an illness, or intentionally induces the symptoms. They might lie to other people about their symptoms or intentionally make themselves sick by misusing medication. The behavior is often an attempt to gain sympathy or attention from others. Munchausen’s syndrome by proxy, or factitious disorder imposed on another (FDIA), is a related condition where a person lies about the symptoms of someone under their care, such as a child.
