A<unk>  is a condition in which a person, without a malingering motive, acts as if they have an illness by deliberately producing, feigning, or exaggerating symptoms, purely to attain (for themselves or for another) a patient's role. People with a<unk>  may produce symptoms by contaminating urine samples, taking hallucinogens, injecting fecal material to produce abscesses, and similar behaviour.<unk>  imposed on self (also called Munchausen syndrome) was for some time the umbrella term for all such disorders.<unk>  imposed on another (also called Munchausen syndrome by proxy, Munchausen by proxy, or<unk>  by proxy) is a condition in which a person deliberately produces, feigns, or exaggerates the symptoms of someone in their care. In either case, the perpetrator's motive is to perpetrate<unk> s, either as a patient or by proxy as a caregiver, in order to attain (for themselves or for another) a patient's role. Malingering differs fundamentally from<unk> s in that the malingerer simulates illness intending to obtain a material benefit or avoid an obligation or responsibility. Somatic symptom disorders, though also diagnoses of exclusion, are characterized by physical complaints that are not produced intentionally.
