It is difficult to say how common factitious disorders are. A review of psychiatric consultations in a tertiary care setting found about 1% of referrals received a diagnosis of factitious disorder. Using an entirely different approach, researchers examined specimens submitted by patients as kidney stones and found that 3.5% were obviously non-physiological.
But whatever the prevalence, the consequences can be serious. They include unnecessary diagnostic procedures or interventions and sometimes self-injury.
