What is the medical term for an adult who pretends to be ill attention but does not have Munchhausen by proxy?

The medical term for an adult who pretends to be ill to gain attention but does not have Munchausen by proxy is factitious disorder imposed on self. This disorder is characterized by a pattern of repeated, deliberate, and obvious lying about or exaggeration of physical or psychological symptoms in the absence of any organic cause or obvious external reward. People with this disorder may present with a variety of symptoms, including pain, gastrointestinal problems, neurological problems, and mental health problems. They may also engage in self-destructive behaviors, such as cutting or burning themselves, in order to gain attention. Treatment for factitious disorder imposed on self typically involves psychotherapy, which can help the person understand the underlying reasons for their behavior and develop healthier ways to cope with stress and attention seeking.
