Factitious disorders (imposed on self)

Overview


Plain-Language Overview

Factitious disorders (imposed on self) are mental health conditions where a person deliberately produces or fakes symptoms of illness. This behavior primarily affects the skin, gastrointestinal system, or other body systems by causing real physical harm or symptoms. People with this disorder may go to great lengths to appear sick, including injuring themselves or altering medical tests. The main health impact is that it leads to unnecessary medical procedures and prolonged suffering. It is important to understand that this is a psychological condition, not a form of malingering or seeking external rewards. The disorder can be challenging to diagnose because the symptoms are intentionally created. It often requires careful evaluation by healthcare professionals to identify the underlying cause.

Clinical Definition

Factitious disorders (imposed on self) are characterized by the intentional production or feigning of physical or psychological symptoms to assume the sick role without obvious external incentives. The core pathology involves conscious symptom fabrication or self-inflicted injury driven by psychological needs rather than external gain. This disorder is distinct from malingering, where external rewards are the motivation. Patients often present with inconsistent clinical findings, unusual disease courses, or symptoms that do not conform to known medical conditions. The condition can involve multiple organ systems and may lead to repeated hospitalizations and invasive diagnostic procedures. It is considered a type of somatic symptom and related disorder with significant psychiatric comorbidity. Recognition is critical to avoid unnecessary interventions and to address the underlying psychiatric illness.
